（二）classification

Common roofing sheet types include flat and corrugated:

Flat plate color steel tiles have a flat surface, characterized by thin thickness, light weight, and high strength. It is mainly used in the manufacturing of building components such as roofs and wall panels, and has good waterproof and leak proof performance. The advantages of flat color steel tiles are light weight and high strength, which can effectively reduce the weight of the structure and have good waterproof performance.

Corrugated color steel tiles have a wavy surface, characterized by high strength, high stiffness, and corrosion resistance. Corrugated color steel tiles are also used to manufacture large building components such as roofs and wall panels, with good waterproof, leak proof, and corrosion-resistant properties. Its disadvantage is that compared to flat color steel tiles, it is heavier and requires more labor for installation

（三）Usage and advantages
1.Corrugated board is suitable for roofs, walls, and interior and exterior wall decorations of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and fast construction, earthquake resistance, fire resistance, rain resistance, long service life, and maintenance free.

2.Corrugated board has many advantages, such as 1. weight, reducing roof load-bearing capacity, 2. thermal insulation, 3. high strength, can be used as a structural board for load-bearing, strong bending and compression resistance, 4. bright color, no need for decoration, and long service life. 5. Flexible and convenient installation

Corrugated roofing sheet come in various shapes and colors, and corresponding shapes and colors can be customized according to customer needs
