SGCC is a hot-dip galvanized steel sheet, whose surface is treated with a hot-dip galvanized layer, showing a bright white color, and obvious hexagonal flower blocks can be seen. The coating of SGCC galvanized sheet can be distinguished by its coating, for example, Z12 means that the total amount of double-sided coating is 120g/mm².
SECC is an electro-galvanized steel sheet, which has an electro-galvanized zinc layer on its surface, presents a uniform gray color, is fingerprint-resistant, has excellent corrosion resistance, and maintains the processability of cold-rolled sheet. Therefore, it is often used in home appliances, computer case shells, and some door panels and panels.
SGLD is a galvanized steel sheet, which is a multi-phase alloy material containing rich aluminum and rich zinc. Due to the characteristics of aluminum and zinc, SGLD has better performance than SGCC, including corrosion resistance, heat resistance, thermal conductivity and heat reflectivity, formability and weldability. Therefore, SGLD is mainly used in places that require good reflectivity, such as the reflective plate inside the oven and the reflective plate of the electric cooker.
In summary, SGCC and SECC are mainly used in home appliances and computer cases, while SGLD is more used in places that require good reflectivity.
