composite decking has a very long life span with very little maintenance needed. consumer reports also estimated that the cost for maintaining a wood deck over a 10 year period could cost in upwards of $5000, while the cost for maintaining a composite deck is estimated at less than $50 per year.
capped on three sides seven trust protect advantage decking capped on three sides seven trust protect advantage decking features deep rich tones with subtle streaking and realistic wood grain patterns. with its proven permatech surface protect advantage offers exceptional stain and fade resistance warranted for 25-years.
pair composite metal deck with diversakore, and gain the benefits of: long spans capable of spans exceeding 30 feet 10.7m shallow depths when designers specify a shallow, structural steel-based slab design, with wide-open spaces free of dropped filler beams
when designed with deep-dek composite deck, versa-floor provides the longest spanning composite floor systems available. with span-to-depth ratios equaling those of traditional cast-in-place concrete and hollow-core plank, a versa-floor deep-dek composite system helps make steel frame solutions affordable. patented side-lap connections achieve composite bond. spans up to 36 deep-ribbed steel-deck profile; factory-closed ends speed installation
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. joist spacing for composite decking
most deck joists are centered 16 in. apart, which is the maximum deck joist spacing for most low-maintenance decking. if you plan to install your decking at a 45-degree angle, your joists may need to be 12 in. apart.
versa-dek composite brings aesthetics to long span applications. versa-floor systems featuring versa-dek composite are ideal for use in mid-rise residential structures. this system provides the thinnest total floor depth, reducing story height while maximizing ceiling height, with clear spans up to 28 ft.
actually he was right. depending on what direction the joists run its only a few more. for the 24ft span it would need 25 joists prob need 2x 14ft to make the span and 16' needing 19 joists. if you want to do diagonal pattern with the decking, then 12' spacing is needed.
long-span deep deck. a variety of long-span decks are available for both roof and form applications. the profile depths of 4 ½ in., 6 in., and 7 ½ in. 114 mm, 152 mm et 190 mm allow the deck to span longer distances between supports and achieve additional load capacity.
triple-span decking uses surface material that spans three joists. metal decking plans call for joists to be 24 inches apart, so a double-span deck plank is at least 48 inches long, and a triple-span deck plank is at least 72 inches long.
the deflection load produces l/240 deflection and is based on the positive moment of inertia calculated at a stress level of 24 ksi 20 ksi for cellular deck . for deck spans over 20 feet, a deflection limit of 1 inch controls. load resistance factor design lrfd tables also show strength / deflection loads.
most efficient building solution. spancrete hollowcore is still as effective and efficient as a building solution today as it was when our first plank was cast over 60 years ago. no other building system accommodates creativity and practicality like spancrete hollowcore floor and roof building systems.
unshored concrete pours for spans up to 22-ft. and shored for spans up to 36-ft. spans up to 36 ft. installs directly onto the frame. deep-ribbed steel-deck profile. factory-closed ends speed installation. safer, cost-effective panelized method. unshored pours up to 22-ft. spans.
do not ever go with 24 oc, the decking will will develop a permanent sag in high traffic areas. you can also double up joists in high traffic areas to avoid 12oc. we use 2x10s on any span over 8', this seems to help with the springy feel of composites. the only way we have been able to make a composite deck feel solid is to way over frame it.
a local sawyer suggested 2' think tongue and grove car decking as an alternative -- with the idea that it may need no or minimal joist structure for support. i did find an article about a house that was built with t and g car decking roof across spans 'up to 8 feet.'
joist span. the closer the joists are to each other, the greater the distance they're able to span safely. two-by-twelve douglas fir joists spaced 12 inches apart on center, for example, can span 20 feet, 7 inches, but the same joists spaced 24 inches part can only span 14 feet, 7 inches.
deep-dek composite systems. when designed with deep-dek composite deck, versa-floor provides the longest spanning composite floor systems available. with span-to-depth ratios equaling those of traditional cast-in-place concrete and hollow-core plank, a versa-floor deep-dek composite system helps make steel frame solutions affordable.
