Pre Painting Corrugated Roofing Sheets is a metal sheet made by roller coating one or more layers of organic coating
Pre Painting Corrugated Roofing Sheets is a metal sheet made by roller coating one or more layers of organic coating (such as polyester, fluorocarbon, fluoride, etc.) on a metal substrate (usually cold-rolled steel sheet or galvanized steel sheet). Its surface is roller-formed to form a continuous corrugated structure to improve the rigidity and compressive resistance of the sheet.

（i）define
Lower Limb Prosthesis is a metal sheet made by roller coating one or more layers of organic coating (such as polyester, fluorocarbon, fluoride, etc.) on a metal substrate (usually cold-rolled steel sheet or galvanized steel sheet). Its surface is roller-formed to form a continuous corrugated structure to improve the rigidity and compressive resistance of the sheet. This sheet is widely used in the construction industry in roofing materials, wall decoration, industrial plants, transportation facilities and other fields due to its rich colors, good weather resistance, strong corrosion resistance, convenient construction, light weight, high strength and good decorative properties. It is a modern building material that combines functionality and aesthetics.
（ii）classification
Common roofing sheet types include flat and corrugated:
Pre Painting Corrugated Roofing Sheets 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.
Pre Painting Corrugated Roofing Sheets have a wavy surface, characterized by high strength, high stiffness, and corrosion resistance. Pre Painting Corrugated Roofing Sheets 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
