Description
YX 76-344-688 High-rib heavy-duty steel floor deck, commonly known in the industry as 3W-type floor decking, is an internationally classic open-face deck type introduced from Europe and America in the 1980s and still in use today. YX 76-344-688 High-rib heavy-duty steel floor decking is made of 1000mm wide hot-dip galvanized steel sheet, roll-formed and cold-bent, with an effective coverage width of 688mm, a wave height of 76mm (3 inches), and a wave pitch of 344mm, consisting of only two waves.
As a high-rib heavy-duty deck in the open-face floor decking family, YX76-344-688, with its 76mm ultra-high ribs and double-peak design, gives the deck excellent cross-sectional moment of inertia and load-bearing capacity. The YX 76-344-688 high-rib heavy-duty steel floor deck is not only a permanent formwork during the construction phase, but also a structural component that works in conjunction with concrete during the service phase. It is particularly suitable for large-span, heavy-load steel structure building systems.
