Yxb40-185-740 closed floor slab

YXB40-185-740 closed floor bearing plate, referred to as 740 load-bearing plate, 740 closed floor bearing plate, YL40-740 (B) floor cover plate, 740 closed plate, rib height of 40mm, composed of 4 waves, each wave pitch of 185mm, the whole Profiled steel plate The effective width is 740mm. The YX40-185-740(B) has an unfolded width of 1250mm and a usage rate of 59.2%.

YX40-185-740 galvanized profiled steel plate because the original plate is very thin, the quality of anti-corrosion coating directly affects the service life, in order to adapt to the processing and anti-rust requirements, the coated steel plate needs to be inspected according to the relevant regulations. Under normal circumstances, the thin steel plate can also be applied with anti-rust paint after pressing according to the requirements of use, or the original stainless steel plate is used.

When YX40-185-740 galvanized profiled steel plate is used as roof panels and wall panels of industrial plants, the amount of steel used per square meter is about 5~11 kg in the case of general no thermal insulation requirements. When there are thermal insulation requirements, mineral wool board, glass wool, foam plastic, etc. can be used as heating materials. Profiled steel plates are combined with concrete to form composite floor slabs, which can eliminate wooden formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the adhesion between the profiled steel plate and the concrete, it is advisable to pre-weld the bolt or press the two-way stiffener on the steel plate.
