Corrugated board, corrugated aluminum plate and corrugated aluminum plate are suitable for the roof, wall and inner and outer wall decoration of industrial and civil buildings, warehouses, special buildings and large-span steel structure houses. Corrugated aluminum plate (corrugated aluminum plate) has the characteristics of light weight, high strength, rich color, convenient construction, earthquake resistance, fire prevention, rain proof, long service life and maintenance free, which has been widely applied. There are many corrugated boards, corrugated aluminum plates and corrugated aluminum plates formed by plastic extrusion, including transparent, opaque and colored ones, and multilayer composite hollow ones. Because of its good plasticity, it can better adapt to the requirements of various architectural forms, but compared with the performance of service life, aesthetic degree and durability, color steel corrugated board is better.
