楼承板的材质一般选用镀锌钢板经辊压冷弯成型，其截面成V型、U型、梯形或类似这几种形状的波形，主要用作永久性模板，也可被选为其他用途。

The material of the building bearing plate is generally selected galvanized steel plate formed by roller pressure cold bending, its section into V-shaped, U-shaped, trapezoidal or similar shape of the waveform, mainly used as a permanent template, can also be selected for other purposes.

网架钢结构桁架楼承板楼板整体刚度大，振动小，隔声性能好，楼板下表面平整，易于建筑装修。钢结构桁架楼承板楼板的施工挠度小于传统压型钢板楼板的挠度。网架钢结构桁架楼承板采用镀锌钢板，具有防腐蚀功能，但在使用阶段不考虑镀锌钢板的作用，无需防腐处理。相对于压型钢板组合楼板，钢结构桁架楼层板具有更优越防腐蚀性能。混凝土楼板的自重完全由钢结构承受，不在混凝土内产生拉应力，使用阶段负弯矩区和正弯矩区混凝土拉应力显著降低，裂缝宽度减小，镀锌钢板的存在避免了楼板下面的暴露裂缝，改善了楼板的使用性能和耐久性。

Grid steel structure truss floor floor overall stiffness, small vibration, good sound insulation performance, the floor surface is flat, easy building decoration.The construction deflection of steel structure truss building slab floor is less than that of traditional pressed steel plate floor.The bearing plate of the grid steel structure truss is made of galvanized steel plate, which has the corrosion prevention function, but the function of galvanized steel plate is not considered in the use stage, and no anticorrosion treatment is needed.Compared with the pressed steel plate composite floor board, the steel structure truss floor board has superior corrosion resistance.The weight of the concrete floor is completely borne by the steel structure, which does not produce tensile stress in the concrete, the concrete tensile stress in the negative bending moment area is significantly reduced, the crack width is reduced, the existence of galvanized steel plate avoids the exposed cracks under the floor, and improves the performance and durability of the floor.
