SGCC is hot-dip galvanized steel sheet, with a bright white surface featuring visible hexagonal patterns due to its hot-dip zinc coating. The coating of SGCC can be distinguished by its designation, such as Z12, indicating a total double-sided coating weight of 120g/mm².
SECC, on the other hand, is electro-galvanized steel sheet, characterized by a uniform gray surface with a zinc coating applied through electrolysis. It is fingerprint-resistant, exhibits excellent corrosion resistance, and retains the workability of cold-rolled steel. Therefore, SECC is commonly used in household appliances, computer case shells, as well as various door panels and faceplates.
SGLD stands for galvanized aluminum-zinc steel sheet, a multi-phase alloy material rich in aluminum and zinc. Due to the properties of aluminum and zinc, SGLD offers superior performance compared to SGCC, including enhanced corrosion resistance, heat resistance, thermal conductivity and reflectivity, formability, and weldability. Consequently, SGLD is primarily utilized in applications requiring high reflectivity, such as reflective panels in ovens and electric cookers.
In summary, SGCC and SECC are mainly used in household appliances and computer cases, while SGLD is more commonly employed in applications demanding high reflectivity.
