SGCC vs SECC Galvanized Steel for Home Appliances

NEWS / wanzhigroup

Galvanized steel sheet is one of the most common metal materials used in the manufacture of home appliances such as refrigerators, washing machines, air conditioners, and microwave ovens. It not only determines the product’s corrosion resistance, appearance quality, and lifespan, but also directly affects manufacturing costs and subsequent coating effects. Currently, the two most commonly used types of galvanized steel in the home appliance industry are SGCC hot-dip galvanized steel sheet and SECC electro-galvanized steel sheet. Although both are galvanized steel, they differ significantly in production processes, coating thickness, corrosion resistance, surface smoothness, and application locations. So, which is more suitable for home appliance manufacturing: SGCC or SECC? What is
