由于建筑中采用压型钢板支撑楼板永久模板，与钢筋混凝土协同工作，不仅要求其具有机械和防腐性能，还要求其具备必要的耐火性能，以满足设计和规范的要求。
建筑工程用压型钢板的尺寸、形状、厚度的允许偏差应符合《建筑用压型钢板》（GB/t12755）的要求；压型钢板的几何尺寸应在出厂前取样，每卷轧制钢板至少抽样3张；压型钢板基材无裂纹，镀锌钢板无锈斑；压型钢板尺寸允许偏差：
A、 板厚极限偏差符合相应的原材料标准；
B波高小于75mm时，波高允许偏差为±1.5mm；波高大于75mm时，波高允许偏差为±2.0mm；
Because the profiled steel plate is used in the building to support the permanent formwork of the floor slab and work together with the reinforced concrete, it not only requires its mechanical and anti-corrosion performance, but also requires the necessary
fire resistance to meet the requirements of the design and specifications.
The allowable deviation of the size, form and thickness of the profiled steel sheet used in the construction engineering shall meet the requirements of profiled steel sheet for building (GB / t12755); the geometric dimension of profiled steel sheet shall
be sampled before leaving the factory, and each roll of the rolled steel sheet shall be sampled for at least 3 pieces; the base material of the profiled steel sheet shall be free of cracks, and the galvanized steel sheet shall be free of rust
spots; the allowable deviation of the profiled steel sheet size:
A. the plate thickness limit deviation conforms to the corresponding standards of raw materials;
B when the wave height is less than 75mm, the allowable deviation of wave height is ± 1.5mm; when the wave height is more than 75mm, the allowable deviation of wave height is ± 2.0mm;
The allowable deviation of C wave distance is ± 2mm; d when the plate length is less than 10m, the allowable deviation of plate length is + 5,0mm, and the lateral bending value is less than 8mm; when the plate length is more than 10m, the allowable
deviation of plate length is + 10,0mm. The requirements of profiled steel plate in building materials industry are very standard, which also greatly improves the quality of construction industry.
