In the field of metal coating materials, 55% Al-Zn Coated Steel Coil occupies an important position with its unique composition ratio and excellent performance. It is associated with Galvalume Steel, Galvanized Steel, Aluminum Coil/Pipe/Plate, Stainless Steel, Aluzinc Steel, and Prepainted Steel Together, they form a rich system of metal materials, yet they demonstrate unique advantages in numerous application scenarios. Galvalume Steel is widely used in large outdoor structures such as building roofs due to its excellent weather resistance and heat reflection ability. Galvanized Steel, relying on the protection of galvanized coatings, has a remarkable anti-rust effect and is commonly used in fields such as steel structures and automotive manufacturing. Aluminum Coil/Pipe/Plate, with its light weight and excellent thermal conductivity, plays a significant role in industries such as aerospace and refrigeration equipment. Stainless Steel is indispensable in fields with extremely high re…
