Product Description Galvanized Sheet
Through electrolytic galvanizing, a uniform and dense zinc layer is finally formed on the surface of the steel, but the mechanical properties of the material are still maintained. Electrogalvanized steel is usually sold in coil or sheet form. EG coil is a kind of material that can be cut, slitted and profiled for other purposes. The steel grade of galvanized steel consists of base metal grade, galvanized (E), galvanized layer type and weight. The electro-galvanized products based on SPCC, SPCD, SPCE, SPCF and SPCG are named SECC, SECD, SECE, SECF and SECG respectively.
Full Cold Galvanizing Process:
Chemical degreasing → hot water washing → water washing → electrolytic degreasing → water washing → acid washing → rust removal → water washing → electrogalvanizing process → water washing → passivation → hot water washing → drying → quality inspection → packaging and sales
