Open floor decking (steel decking, building profiled steel plate) is made of galvanized steel plate that is rolled and cold-bent. Its cross-section is shaped, square, trapezoidal or similar to these shapes, and is used as a permanent formwork for concrete floor slabs. It is also the lower stress-bearing steel bars of the floor that participate in the stress calculation of the floor and work together with the concrete to form a composite floor. Main features
It adapts to the requirements of rapid construction of the main steel structure, can provide a firm working platform in a short time, and can adopt the flow construction of laying profiled steel plates on multiple floors and pouring concrete slabs in layersbr/> In use The stage floor bearing slab serves as the tensile steel bar for the concrete floor slab, which also improves the stiffness of the floor slab and saves the amount of steel bars and concrete.
The embossing on the surface of the profiled board creates a super strong bonding force between the floor decking and the concrete, making the two form a whole. Together with the stiffening ribs, the floor decking system has a high bearing capacity.br/> On the cantilever Under certain conditions, the open floor decking is only used as a permanent formwork. The length of the overhang can be determined according to the cross-sectional characteristics of the floor deck. In order to prevent the cantilever board from cracking, it is necessary to add negative reinforcement at the support according to the design of the structural engineerbr/> Our company's floor bearing board has passed the fire resistance limit test of the National Fixed Fire Extinguishing System and Fire-Resistant Component Quality Inspection Center. As a composite building The bearing plate does not require fireproof spraying, thus greatly reducing the project cost.
The types of open floor decking supplied by our company are
Product application products are widely used in power plants, electrical equipment companies, automobile showrooms, steel structure workshops, cement warehouses, steel structure offices, airport terminals, sports Steel structure buildings such as venues, concert halls, Olympic venues and stadiums.
