Стандартные размеры листов профнастила: 6 метров, 3 метра

Простота монтажа и стандартные строительные размеры (3м, 6м) делают профнастил очень популярным материалом. Размеры профлиста могут быть разные и напрямую зависят от его назначения.

Длина

Профнастил изготавливается из рулонной стали, поэтому длина листа может быть практически любой и зависит лишь от параметров, предоставленных заказчиком. В отношении длины самыми ходовыми являются оцинкованные профлисты с размерами 3 метра и 6 метров.

Ширина

Когда речь идет о ширине профилированного листа, следует помнить о том, что «габаритная ширина» и «полезная ширина» — это разные размеры. Технология укладки профиля требует перекрытия на длину одной гофры («внахлест»), поэтому полезная ширина меньше габаритной на 40-80 мм.

Толщина

Стандартные размеры толщины оцинкованного листа варьируют от 0,5 до 1 мм. Чем больше толщина листа, тем он прочнее.

Высота

Высотой профлиста считается расстояние между 2-мя смежными гофрами, поэтому размеры высоты зависят от рисунка погиби.

Профлисты стандартных размеров (длиной 3 м и 6м) всегда есть в наличии на складе. Принимаем  заказы на изготовление профнастила любой длины.

You will also want to add an additional 10% to 15% waste beyond normal waste. 90008 90013 90008 90013 .90000 Deck Joist Sizing and Spacing 90001 90002 Enjoying your deck on a beautiful summer day is the perfect way to entertain guests outside or just unwind and relax. And while it’s important to have a deck that’s aesthetically pleasing to you, the most vital part about your deck is making sure it’s structurally sound. That includes knowing the difference between a joist and a beam and what purpose they serve to your deck and its functionality and safety. 90003 90004 What Is a Joist? 90005 90002 Joists are the repeated structural members that are used to build a deck frame.The minimum size joist to be used in deck construction depends on the number of footings and beams that will be installed. 90003 90004 What Is a Beam? 90005 90002 A beam is the main load-bearing element for the structural soundness of your deck’s roof. It’s not only responsible for supporting the weight of the joists, but other building elements, as well. 90003 90004 Deck Joist Spacing 90005 90002 A lot of questions revolve around joists when it comes to building a deck. What is the proper placement? How far apart are floor joists placed? How do I keep them even? 90003 90002 In general terms, joists spaced 16 inches on center can span 1.5 times in feet their depth in inches. A 2×8 up to 12 feet; 2×10 to 15 feet and 2×12 to 18 feet. The larger the deck, the larger the joists. 90003 90002 In typical deck construction, with a ledger on one side of the joist and beam on the other, the size of the joists is driven by the size of the deck and based on the general maximum spans mentioned above. For best results, refer to our wood and composite deck joist span table. 90003 90020 90021 90022 90023 Joist Spacing (o.c.) 90024 90023 90024 90023 12 «90024 90023 16 «90024 90023 24 «90024 90033 90022 90035 Species 90036 90035 Size 90036 90039 Allowable Span 90036 90033 90022 90043 Southern Pine 90036 90035 2×6 90036 90035 9′-11 «90036 90035 9′-0 «90036 90035 7′-7 «90036 90033 90022 90035 2×8 90036 90035 13′-1 «90036 90035 11′-10 «90036 90035 9′-8 «90036 90033 90022 90035 2×10 90036 90035 16′-2 «90036 90035 14′-0 «90036 90035 11′-5 «90036 90033 90022 90035 2×12 90036 90035 18′-0 «90036 90035 16′-6 «90036 90035 13′-6 «90036 90033 90022 90043 90002 Douglas Fir-Larch, 90003 90002 Hem-Fir, 90003 90002 Spruce-Pine-Fir 90003 90036 90035 2×6 90036 90035 9′-8 «90036 90035 8′-4 «90036 90035 6′-10 «90036 90033 90022 90035 2×8 90036 90035 12′-8 «90036 90035 11′-1 «90036 90035 9′-1 «90036 90033 90022 90035 2×10 90036 90035 15′-8 «90036 90035 13′-7 «90036 90035 11′-1 «90036 90033 90022 90035 2×12 90036 90035 18′-0 «90036 90035 15′-9 «90036 90035 12′-10 «90036 90033 90022 90043 90002 Redwood, 90003 90002 Western Cedars, 90003 90002 Poderosa Pine, Red Pine 90003 90036 90035 2×6 90036 90035 8′-10 «90036 90035 8′-0 «90036 90035 6′-10 «90036 90033 90022 90035 2×8 90036 90035 11′-8 «90036 90035 10′-7 «90036 90035 8′-8 «90036 90033 90022 90035 2×10 90036 90035 14′-11 «90036 90035 13′-0 «90036 90035 10′-7 «90036 90033 90022 90035 2×12 90036 90035 17′-5 «90036 90035 15′-1 «90036 90035 12′-4 «90036 90033 90180 90181 90002 90003 90002 For conventional guardrail post installation bolted to the side of the framing, larger framing will provide more strength in the rails.For upper-level decks, 2×10 is recommended as the minimum size to use for strong guard post connections. 2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Similar to guards, if stairs are to be hung from the side of an upper-level deck, 2×10 as a minimum is recommended, as it will exceed the depth of the first step. 90003 90002 Joist hangers are used to attach the ends of joists to the face of a beam or a ledger board. If you identify a crown in the board, you should always install it upwards.The crown will eventually settle after completing construction and should stiffen in the proper position after drying. 90003 90002 The layout term for joists is «On Center,» which is the center-to-center measurement from one joist to the next. Most decks use 16 «on center spacing for joists. Most decking is not strong enough to support longer spans than 16». Some builders reduce joist spacing to 12 «on center to strengthen the deck frame or to increase maximum allowable joist spans. 90003 90004 Joist Spacing for Composite Decking 90005 90002 Before building a composite deck, always read the installation instructions from the manufacturer, paying special attention to the required joist spacing for composite decking.Most composite decking materials, like Trex composite decking, require minimum joist spacing for composite decking at 16 «on center spacing for straight decking and 12» on center joist spacing for 45-degree angle diagonal decking. 90003 90002 Also, many composite decking materials require 12 «or even 10» on center stair stringers spacing to support composite stair treads. If you are installing composite decking over an existing frame, you may need to install new intermediate joists or stair stringers to meet the installation requirements.90003 90002 Since most composite products are not as inflexible as their wood counterparts, they do not hide imperfections in the framing quite as well. This can sometimes cause an uneven surface. That’s why stretching a string across the joist spacing for composite deck boards can help detect spots that may be higher than others. These spots can be addressed with a power hand planer to give you a nicer, smoother surface for the deck of your dreams. 90003 90198 90002 Laying out the first joist position on an angle.90003 90002 Using a scrap piece of wood as a guide to locate the first joist in the situation of an angled corner. 90003 90198 90002 Use a sharpie or construction pencil to mark your joists. 90003 90002 Marking joist locations at 16 «on center spacing on the header with a marker. 90003 90198 90002 Toe nailing a joist to the rim joist.90003 90002 Installing a joist over a beam. Make sure the top of the joist is flush with the header. Toe nailing will fail in 75+ mile per hour winds. Use hurricane clips in high wind areas. 90003 90198 90002 Use a chisel to notch beams to create a level frame. 90003 90002 Notching a joist over a beam. This joist was 1/4 «higher than all the others. You can notch out a section of the joist or add shims to a narrow joist to even out the top of the deck frame.90003 90198 90002 Always fill all the nail holes for deck harware. 90003 90002 Using a palm-nailer or hammer to install a joist hangers with 1-1 / 2 «teco nails to the ledger board. 90003 90198 90002 Inspect the board and trim off the rougher edge. 90003 90002 Measuring the 2×10 pressure treated joist length to prepare for cutting.Use a speed square to square off your joists. 90003 90002 Installing 2×10 pressure treated joists at 16 «on center.

InterNACHI estimates that of the 45 million existing decks, only 40% are completely safe. 90003 90002 Because decks appear to be simple to build, many people do not realize that decks are, in fact, structures that need to be designed to adequately resist certain stresses.Like any other house or building, a deck must be designed to support the weight of people, snow loads, and objects. A deck must be able to resist lateral and uplift loads that can act on the deck as a result of wind or seismic activity. Deck stairs must be safe and handrails graspable. And, finally, deck rails should be safe for children by having proper infill spacing. 90003 90002 A deck failure is any failure of a deck that could lead to injury, including rail failure, or total deck collapse.There is no international system that tracks deck failures, and each is treated as an isolated event, rather than a systemic problem. Very few municipalities perform investigations into the cause of the failure, and the media are generally more concerned with injuries rather than on the causes of collapses. Rail failure occurs much more frequently than total deck collapses; however, because rail failures are less dramatic than total collapses and normally do not result in death, injuries from rail failures are rarely reported.90009 90003 90002 This document does not address specific building codes, balconies, lumber species, grade marks, decks made of plastics or composites, mold, or wood-destroying insects. 90003 90013 90014 90003 90002 The image above depicts an evenly distributed deck load. Building codes require decks to be designed to carry a uniformly distributed load over the entire deck. If evenly distributed, half of the load is carried by the deck-to-house connection, and the other half is carried by the posts.90003 90018 90002 The image above depicts a typical deck load distribution. People tend to gather near the railings of a deck, and so more load is likely carried by the posts. 90003 90002 90003 90002 Hot tubs filled with water and people are heavy and can weigh a couple of tons. Most decks are designed for loads of 40 to 60 pounds per square foot. Hot tubs require framing that can support over 100 pounds per square foot. 90003 90002 90003 90002 Footings and Posts: 90003 90002 90003 90002 Required footing depths vary based on local building codes.The depth is normally below the frost line, or 12 inches (where frost lines are not applicable). 90003 90013 90034 90003 90002 The above image depicts the 90037 7-Foot Rule. 90038 On steep properties, the slope of the ground around the footing could affect the footing’s stability. The 90037 7-Foot Rule 90038 states that there should be a least 7 feet between the bottom of a footing and daylight. 90003 90002 90003 90002 Posts in contact with soil should be pressure-treated and oriented so the cut end is above grade.90003 90046 90002 The image above depicts a free-standing deck (not attached to the home or building). A footing near a home must be on undisturbed soil. Some codes consider soil to be «undisturbed» if it has not been disturbed in more than five years. It may be difficult to find undisturbed soil near the foundation of a new home. 90003 90049 90002 The image above depicts a post base that is not attached to its footing. Posts should be connected to their footings so that the posts do not lift or slip off.90003 90013 90053 90003 90002 The image above depicts a pre-cast concrete pier. Posts can lift out of pre-cast concrete piers, and piers can slide. Posts should be connected to their footings so that the posts do not lift or slip off. 90003 90013 90058 90003 90002 The image above depicts a proper post-to-footing connection. Posts should be connected to their footings so that the posts do not lift or slip off their footings. 90003 90062 90002 The image above depicts an adjustable post-to-footing connection.Posts should be connected to their footings so that the posts do not lift or slip off their footings. 90003 90013 90066 90003 90002 The above image depicts a lawn sprinkler keeping a deck post wet. Lawn sprinkler systems that regularly keep the deck wet contribute to decay. 90003 90070 90002 The image above depicts a downspout contributing to post decay. Downspouts should not discharge near deck posts. 90003 90073 90002 The image above depicts the indentation left over from the footing hole, causing a puddle.Puddles contribute to post decay. 90003 90002 90003 90002 Wood can decay and degrade over time with exposure to the elements. Decay is a problem that worsens with time. Members within the deck frame that have decayed may no longer be able to perform the function for which they were installed. Paint can hide decay from an inspector and so should be noted in the report. 90009 90003 90002 90003 90013 90084 90003 90002 The image above depicts a «pick test.»The pick test uses an ice pick, awl or screwdriver to penetrate the wood surface. After penetrating the wood, the tool is leveraged to pry up a splinter, parallel to the grain, away from the surface. The appearance and sound of the action is used to detect decay. The inspector should first try the pick test in an area where the wood is known to be sound to determine a «control» for the rest of the inspection. Decayed wood will break directly over the tool with very few splinters , and less or almost no audible noise compared to sound wood.The pick test can not detect decay far from the surface of the wood. 90003 90088 The image above depicts a pick test on a deck post. Although deck inspections are visual-only inspections, inspectors may want to dig down around posts and perform pick tests just below grade level to look for decay. 90009 90090 90091 90092 90002 The image above depicts a high deck being supported with 4 «x 4» posts. Tall 4 «x 4» posts twist under load and 4 «x 4» posts, even when treated, decay below grade too quickly.In all but the lowest of decks, deck posts should be at least 6 «x 6», and be no higher than 12 feet; 14 feet is acceptable if cross-bracing is used. 90003 90002 90003 90002 Often, the bottoms of the stringer boards for deck stairs have been found to rest on soil, concrete block or rock, as opposed to resting on posts installed below the frost line. Posts set on soil are subject to rot due to moisture. Posts that are set in unsound footings may cause movement and make the deck above unstable.90003 90002 90003 90002 Girders and Beams: 90009 90003 90104 90002 The image above depicts the minimum distance of untreated support members from grade. Untreated joists should be at least 18 inches away from the ground. Girders should be 12 inches away from the ground. However, in many situations, exceptions are made where the elevation of the home does not provide for these minimum distances and the climate is very dry. 90003 90009 90108 90002 The image above depicts a girder improperly relying on the sheer strength of lag bolts.Girders should bear directly on posts. 90003 90111 90002 The image above depicts a girder properly resting on a notched post. Girders should bear directly on posts. 90003 90114 90002 The image above depicts a girder properly resting on a post. Girders should bear directly on posts. 90003 90002 90003 90002 Girders supporting joist should not be supported by deck ledgers or band joists. 90003 90121 90002 The image above depicts a butt joint improperly located within a girder span. Butt joints in a girder span are generally not permitted unless specially engineered.Butt joints typically must be located above posts. 90003 90124 90009 The image above depicts notches in a supporting beam. Notches must be less than one-quarter the depth of the member. On the tension and compression faces, the notch depth must be less than one-sixth of the member’s depth, and the notch length must be less than one-third of the member’s depth. Notches are not permitted in the middle third of spans, or on the tension face of members that are greater than 3½ inches thick. 90126 90002 The image above depicts a level being used to check for beam sag.Even with a carpenter’s level, it can be difficult to see beam sag from the front. 90003 90129 90002 The image above depicts beam sag being eyed-up. Often it is easier to detect beam sag by eye than with a level by looking along the bottom edge of the beam. 90009 90003 90002 90003 90002 Ledger Connection: 90003 90002 90003 90002 The most common cause of deck collapse is when a ledgers pulls away from the band joists of homes and buildings. 90003 90002 90003 90002 The two most common ways to correctly attach a ledger to a structure are with lag screws or through-bolts.The installation of through-bolts requires access to the back-side of the rim joist which, in some cases, is not possible without significant removal of drywall within the structure. 90003 90002 90003 90002 Most building codes state that, where positive connections to the primary building structure can not be verified during inspection, decks shall be self-supporting (free-standing). 90003 90002 90003 90002 Determining the exact required spacing for the ledger fasteners is based on many factors, including: 90003 90153 90154 joist length; 90155 90154 type of fastener; 90155 90154 diameter of fastener; 90155 90154 sheathing thickness; 90155 90154 use of stacked washers; 90155 90154 type of wood species; 90155 90154 moisture content; 90155 90154 band joist integrity; and 90155 90154 deck loads… 90155 90172 90002 … and so is beyond the scope of a visual inspection. However, the spacing of ledger fasteners is primarily determined by the length of the joists. 90003 90002 90003 90002 InterNACHI’s ledger fastener spacing formula provides inspectors with a rule-of-thumb: 90003 90179 90002 90090 90037 On-center spacing of ledger fasteners in inches = 100 90038 ÷ 90037 joist length in feet. 90038 90092 90003 90188 90002 A deck with substantially fewer ledger fasteners than that recommended by InterNACHI’s formula may be unsafe.90003 90002 90003 90013 90194 90003 90002 The image above shows the minimum distance of fasteners to the edges and ends of a ledger board. Lag screws or bolts should be staggered vertically, placed at least 2 inches from the bottom or top, and 5 inches from the ends of the ledger board. Some codes permit the lag screws or bolts to be as close as 2 inches from the ends of the ledger board; however, avoiding the very ends of the ledger boards minimizes splitting from load stress.90003 90002 Through-bolts should be a minimum of ½-inch in diameter, and have washers at the bolt head and nut. Lag screws should also be a minimum of ½-inch in diameter and have washers. Expansion and adhesive anchors should also have washers. 90003 90002 90003 90002 Deck ledgers should be of at least 2’x 8 ‘pressure-treated wood. 90003 90002 90003 90002 Ledger Board and Band Joist Contact: 90003 90002 90003 90210 90002 The image above depicts washers being used as spacers between the ledger board and band joist, which is incorrect.90003 90002 90003 90002 In some cases, the ledger board and band joist are intentionally kept separated by a stack of washers on the lag screw or bolts to allow water to run between the two boards. In other cases, there is insulation between the two boards. Even worse is when the siding or exterior finish system was not removed prior to the installation of the ledger board. Situations like this, where the ledger board and band joist are not in direct contact, significantly reduce the strength of the ledger connection to the structure and are not recommended by InterNACHI, unless the two members are sandwiching structural sheathing.90003 90002 90003 90219 90002 The image above depicts a ledger board and band joist sandwiching the structural sheathing (correct). 90003 90002 90003 90002 All through-bolts should have washers at the bolt head and nut. 90003 90226 90002 The image above depicts a hold-down tension device. The 90037 2007 IRC Supplement 90038 requires hold-down tension devices at no less than two locations per deck. 90003 90002 90003 90002 Codes in some areas outright forbid attaching a ledger board to an open-web floor truss.90003 90235 90002 The image above depicts a ledger board attached to a concrete wall. Caulking rather than flashing is used. 90003 90238 90002 The image above depicts a ledger board attached to hollow masonry. When the ledger is attached to a hollow masonry wall, the cell should be grouted. 90003 90002 90003 90002 90003 90245 90002 The image above depicts a ledger board improperly supported brick veneer. Ledger boards should not be supported by stone or brick veneer. 90003 90002 90003 90002 Ledger boards should not be attached directly (surface-mounted) to stucco or EIFS, either.Stucco and EIFS have to be cut back so that ledger boards can be attached directly to band joists; however, cut-back stucco and EIFS are difficult to flash and weather-proof. 90003 90252 90009 The image above depicts both over and under ledger board flashing. The ledger board should always be flashed even when the home or building has a protective roof overhang. 90002 90003 90002 Aluminum flashing is commonly available but should not be used. Contact with pressure-treated wood or galvinized fasteners can lead to rapid corrosion of aluminum.90003 90258 90002 The image above depicts a deck ledger attached to an overhang. Decks should not be attached to overhangs. 90003 90261 90002 The image above depicts proper framing around chimneys or bay windows that are up to 6 feet wide. Framing around chimneys or bay windows that are more than 6 feet wide requires additional posts. 90003 90264 90009 The image above depicts a cantilevered deck. Joists should be cantilevered no more than one-quarter of the joist length and three times the joist width (nominal depth).Both conditions must be true. 90266 90009 90002 The image above depicts a joist cantilever in the front of the deck and girder cantilevers on both sides of deck posts. Joists should be cantilevered no more than one-quarter the joist length and three times the joist width (nominal depth). Girders can be cantilevered over their posts no more than on-quarter the girder length. 90003 90002 90003 90002 There are three ways a joist can be attached to a ledger: 90003 90274 90002 The first is by resting the joist on a ledger strip.The image above depicts a joist properly resting on a 2 «x 2» ledger strip. 90003 90277 90002 The second is by notching over a ledger strip. The image above depicts a notched joist properly resting a 2 «x 2» ledger strip. 90003 90280 90002 The third is by hanging the joists with joist hangers. The image above depicts joists properly attached to a ledger by way of metal joist hangers. 90003 90283 90002 The image above depicts a joist cut too short. Joists may rest on 2 «x 2» ledgers like the one above (or in joist hangers), but joists must be cut long enough to reach the ledger or band joist that is supporting them.90003 90286 90002 The image above depicts joists that are not fully resting in their joist hangers. Joists should be fully resting in their joist hangers. 90003 90002 90003 90002 Bracing: 90003 90293 90002 The image above depicts a deck with post-to-joist diagonal bracing. Decks greater than 6 feet above grade should have diagonal bracing from posts to girder, and from posts to joists. 90003 90296 90002 The image above depicts a deck with post-to-girder diagonal bracing. Decks greater than 6 feet above grade should have diagonal bracing from posts to girder, and from posts to joists.90003 90002 90003 90002 Free-standing decks (not supported by the home or building) should have diagonal bracing on all sides. 90003 90303 90002 The image above depicts underside diagonal bracing of a deck. Decks greater than 6 feet above grade that do not have diagonal decking should have diagonal bracing across the bottoms of the joists to keep the deck square. A deck that is not held square could permit the outer posts to lean to the right or left, parallel to the ledger board, and thus twist the ledger away from the home or building.90003 90002 90003 90002 Cracks: 90003 90002 90003 90002 As wood ages, it is common for cracks to develop. Large cracks (longer than the depth of the member) or excessive cracking overall can weaken deck framing. Toe-nailed connections are always at risk for splitting. Splitting of lumber near connections should be noted by the inspector. 90003 90002 90003 90002 Connectors and Fasteners: 90003 90002 90003 90002 The inspector should note missing connectors or fasteners. All lag screws and bolts should have washers.90003 90322 90002 The image above depicts a «hammer test.» Depending on how the deck was built, vital connections may have degraded over time due to various factors. Issues such as wobbly railings, loose stairs, and ledgers that appear to be pulling away from the adjacent structure are all causes for concern. The tightness of fasteners should be checked. If it is not possible to reach both sides of a bolt, it may be struck with a hammer. The ring will sound hollow with vibration if the fastener is loose.The ring will sound solid if the connection is tight. The hammer test is subjective, so the inspector should hammer-test bolts that can be confirmed as tight or loose, and compare the sounds of the rings to develop a control. 90003 90002 90003 90002 Corrosion of Connectors and Fasteners: 90003 90002 90003 90002 All screws, bolts and nails should be hot-dipped galvanized, stainless steel, silicon bronze, copper, zinc-coated or corrosion-resistant. Metal connectors and fasteners can corrode over time, especially if a product with insufficient corrosion-resistance was originally installed.Corrosion of a fastener affects both the fastener and the wood. As the fastener corrodes, it causes the wood around it to deteriorate. As the fastener becomes smaller, the void around it becomes larger. Inspectors normally do not remove fasteners to check their quality or size, but if the inspector removes a fastener, s / he should make sure that removal does not result in a safety issue. Fasteners removed should be from areas that have the greatest exposure to weather. Some inspectors carry new fasteners to replace ones they remove at the inspection.90003 90002 90003 90002 Posts and Rails: 90003 90002 90003 90339 90002 The image above shows a guardrail supported solely by balusters. Guardrails should be supported by posts every 6 feet. 90003 90342 90002 The image above depicts a notched-deck guardrail post attachment. This common notched-type of attachment is permitted by most codes, but could become unsafe, especially as the deck ages. Because of leverage, a 200-pound force pushing the deck’s guardrail outward causes a 1,700-pound force at the upper bolt attaching the post.It is difficult to attach deck guardrail posts in a manner that is strong enough without using deck guardrail post brackets. 90003 90345 90002 The image above depicts a notched-deck guardrail post attachment. This notched-around-decking type of attachment is permitted by most codes, but could become unsafe, especially as the deck ages. Because of leverage, a 200-pound force pushing the deck’s guardrail outward causes a 1,700-pound force at the upper bolt attaching the post. It is difficult to attach deck guardrail posts in a manner that is strong enough without using deck guardrail post brackets.90003 90348 90002 The image above depicts a deck guardrail post properly attached with brackets. Because of leverage, a 200-pound force pushing the deck’s guardrail outward causes a 1,700-pound force at the upper bolt attaching the post. It is difficult to attach deck guardrail posts in a manner that is strong enough without using deck guardrail post brackets. 90003 90351 90002 The image above depicts a post and balusters cut level and not shedding water. The end-grain of vertical posts and balusters should not be cut level.90003 90354 90002 The image above depicts a post and balusters properly cut at angles to shed water. The end-grain of vertical posts and balusters should be cut at an angle. 90003 90002 90003 90002 Missing Guardrails: 90003 90002 90003 90002 Decks that are greater than 12 inches above adjacent areas should have guardrails around the edges. Some codes require guardrails only around the edges of decks 30 inches or higher. 90003 90002 90003 90002 Improper Guardrail Height: 90003 90002 90003 90002 Most residential codes require the top of the guardrail to be at least 36 inches from the deck surface.Most commercial code height is 42 inches. 90003 90373 90009 90002 The image above depicts child-unsafe guardrail infill. Infill should not permit a 4-inch sphere to pass through. 90003 90377 90002 The image above depicts horizontal balustrades. Ladder-type guardrail infill on high decks is prohibited by some local codes because they are easy for children to climb over. 90003 90002 90003 90002 Decking: 90009 90003 90385 90009 90002 The image above depicts deck framing near a chimney or bay window.The ends of decking boards near the chimney or bay window can extend unsupported up to 6 inches. 90003 90389 The above image depicts decking that is laid too tight. Decking should have 1/8-inch gaps between boards so that puddles do not form. 90009 90391 90009 90002 The above image depicts decking that is properly spaced. Decking should have 1/8-inch gaps between boards so that puddles do not form. 90003 90395 90002 The image above depicts decking that is not staggered properly. Decking should be staggered so that butt joints do not land on the same joist side by side.90003 90398 90002 The image above depicts decking lengths. Some are too short. Each segment of decking should bear on a minimum of four joists. 90003 90002 90003 90002 Decking should be attached to the floor joists and rim joist, especially in high-wind areas. 90003 90002 90003 90002 Decking Nail Pull-Out: 90003 90002 90003 90002 Inspectors should look for splitting in decking and nail pull-out. Aside from the structural issue, nails that have pulled out or screws that are not driven into the decking fully can cause injury to bare feet.90003 90002 90003 90002 Stairs: 90003 90417 90002 The image above depicts a deck stair stringer. Stair stringers shall be made of 2 «x 12» lumber at a minimum, and no less than 5 inches wide at any point. 90003 90420 90009 90002 The image above depicts deck stair stringers. Stringers should be no more than 36 inches apart. 90003 90424 90002 The image above depicts ledger strips properly located under stair treads. Where solid stringers are used, stair treads should be supported with ledger strips (as depicted), mortised, or supported with metal brackets.90003 90427 90002 The image above depicts a set of stairs with open risers. Most deck stairs have open risers and are not safe for children. Risers may be open but should not allow the passage of a 4-inch diameter sphere. 90003 90430 90002 The image above depicts stair riser height. To minimize tripping, the maximum variation amongst riser heights (difference between the tallest and shortest risers) should be no more than 3/8-inch. 90003 90002 90003 90002 The bottom step of a stairway leading up to a deck is typically at a different height than the rest of the steps.This can present a trip hazard. 90003 90002 90003 90002 Steps with open risers can present a tripping hazard if a user catches his foot by stepping too far into the tread. To mitigate this hazard, the risers can be closed or the treads can be made deeper. 90003 90002 90003 90002 Deck Lighting: 90003 90002 90003 90002 Decks rarely have light sources that cover the entire stairways. Any unlit stairway is a safety issue. 90003 90002 90003 90002 Stair Handrails: 90003 90002 90003 90002 Stairs with four or more risers should have a handrail on at least one side.According to the 90037 International Standards of Practice for Inspecting Commercial Properties, 90038 ramps longer than 6 feet should have handrails on both sides. 90003 90459 90002 The image above depicts proper stair handrail height. Handrail height should be between 34 and 38 inches measured vertically from the sloped plane adjoining the tread nosing. 90003 90462 90002 The image above depicts a stair handrail that is not graspable. Many deck handrails improperly consist of 2 «x 6» lumber or decking.Handrails should be graspable, continuous and smooth. 90003 90002 90003 90467 90009 90002 90003 90002 The images above show that handrail ends should be returned or terminate in newel posts. 90003 90002 90003 90002 The next three images depict graspable handrails: 90003 90477 90478 90002 90003 90002 90003 90013 90484 90003 90002 The three images directly above depict graspable handrails. Many deck handrails improperly consist of 2 «x 6» lumber or decking. Handrails should be graspable, continuous and smooth.90003 90488 90002 The image above depicts the minimum distance between stair handrail posts. Stair handrails should have posts at least every 5 feet. 90003 90491 90002 The image above depicts permitted spacing at stairs. Larger spacing presents a child-safety issue. 90003 90002 90003 90002 Electrical Receptacle: 90003 90498 90002 The image above depicts a deck with an electrical receptacle, but the receptacle does not have a weatherproof cover. As of 2008, the National Electric Code requires at least one receptacle outlet on decks that are 20 square foot or larger.90003 90501 90002 The image above depicts a weatherproof receptacle cover. The deck receptacle should have a weatherproof cover. 90003 90002 90003 90002 Deck Location: 90003 90508 90002 The image above depicts a deck located above a septic tank access. Decks should not be located where they might obstruct septic tank accesses, underground fuel storage tanks, well heads, or buried power lines. 90003 90511 90002 The image above depicts a deck obstructing a basement bedroom’s emergency egress window.Egress openings under decks and porches are acceptable, provided the escape path is at least 36 inches (914 mm) in height, and the path of egress is not obstructed by infill or lattice. 90003 90002 90003 90179 90179 90179 90002 Are you planning on entertaining on your deck? 90009 Have your neighborhood InterNACHI member 90009 inspect it first! 90003 90188 90188 90188 90179 90527 90002 90003 90188 90531 90009 90002 90003 90002 90003 90002 90009 90003 90002 / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ 90003 90002 90003 90179 90002 90037 July 22 2009 90009 90038 90003 90002 90037 90038 90003 90002 90037 Nick, 90038 90003 90002 90037 90038 90003 90037 This is a very worthwhile and important message that needs to be heard by as many people as possible.When we look at the work we all do, consumer safety and awareness would have to be the most lasting impression we can provide. At the end of the day, you want to believe you are making a difference. I can not think of a better way to do this than making homes (decks) safer. This is a task that will take the efforts of many to reach all consumers. I believe we all need to reach out and create relationships to help spread the word. Thank you for opening the door and I hope we can all step through and make a difference.90002 Have a great day and I am looking forward to working with you all. 90003 90038 90009 90037 Shawn 90038 90002 Shawn Miller, President 90009 North American Deck and Rail Association 90009 www.nadra.org 90009 [email protected] 90003 90188.90000 Choosing a Longboard Skateboard Deck 90001 1-877-791-9795 FREE SHIPPING! orders over $ 89 Promo Code 90002 90003 Gift Cards 90004 90003 Wish List 90004 90003 Buying Guides 90004 90003 Help 90004 90003 Cart (0) 90004 90013 90002 90003 Skateboards 90002 90003 Completes 90002 90003 Build Your Own 90004 90003 Warehouse Completes 90004 90003 Complete Skateboards 90004 90003 Assembly Option 90004 90013 90004 90003 Decks 90002 90003 Skateboard Decks 90004 90003 Longboards 90004 90003 Old School 90004 90003 Grip Option 90004 90013 90004 90003 Trucks 90002 90003 Skateboard Trucks 90004 90003 Reverse Kingpin 90004 90003 Truck Combos 90004 90013 90004 90003 Wheels 90002 90003 Skateboard Wheels 90004 90003 Longboard & Cruiser 90004 90013 90004 90003 Components 90002 90003 Bearings 90004 90003 Grip Tape 90004 90003 Hardware 90004 90003 Risers 90004 90003 Board Rails 90004 90013 90004 90013 90004 90003 Accessories 90002 90003 Skateboard 90002 90003 Skate Tools 90004 90003 Skate Wax 90004 90003 Bushings 90004 90003 Pivot Cups 90004 90003 Bearing Lubes 90004 90003 Skateboard Displays 90004 90013 90004 90003 Glove Box 90002 90003 Sunglasses 90004 90003 Pins & Buttons 90004 90003 Patches 90004 90003 Shoe Repair 90004 90003 Air Fresheners 90004 90003 Health & Beauty 90004 90013 90004 90003 Junk Drawer 90002 90003 Stickers 90004 90003 Toys & Games 90004 90003 Home & Living 90004 90003 Drinkware 90004 90003 Candles 90004 90003 DVDs 90004 90013 90004 90003 Ramps & Rails 90002 90127 90013 90004 90013 90004 90013.
