Wen he color steel profiled board is used as the house panel and wall panel of the industrial plant, the steel consumption per square meter is about 5-11kg without the requirement of heat preservation. When insulation requirements are available, mineral wool boards, glass wool and foam plastics can be used as insulation materials. The combination of profiled slab and concrete can save wood formwork and be used as load-bearing structure. At the same time, in order to strengthen the binding force between profiled plate and concrete, it is advisable to pre weld stud or press two-way stiffener on steel plate. The common thickness of roof and wall is 0.4-1.6mm; when it is used for bearing floor or silo, the thickness is 2-3mm or more. The wave height generally varies from 10 to 200 mm. When there is no stiffening, the height thickness ratio should be controlled within 200. When the full-length roof slab is used, the slope can be 2-5%, and the deflection shall not exceed L / 300 (L is the calculated span length).Due to the thin original plate, the quality of anti-corrosion coating directly affects the service life of the color steel profiled plate. In order to meet the requirements of processing and rust prevention, the coated steel plate shall be inspected in accordance with the relevant regulations. In general, the steel sheet can also be painted with antirust paint after pressing according to the use requirements, or the original stainless steel sheet can be used.
