DX51d refers to a grade of hot-dip galvanized steel with a specific chemical composition and mechanical properties. It's one of the most commonly used grades for galvanized steel. The "DX" prefix indicates the steel's composition, while "51" refers to the minimum yield strength in megapascals (MPa). In the case of DX51d, the "d" stands for drawing quality, indicating that the steel is suitable for deep drawing and forming processes.
0.2mm cold rolled galvanized steel coils indicate the thickness of the steel and the manufacturing process used. Cold-rolled steel is processed at room temperature, which results in a smoother and more refined surface finish compared to hot-rolled steel. The 0.2mm thickness indicates that the steel has been rolled to a thickness of 0.2 millimeters.
Thin galvanized steel sheets are used for automotive body panels due to their formability, corrosion resistance, and paint adhesion properties.
