SPCC, SPCD, SPCE, and SPCG galvanized coils (compliant with JIS G3141 standard, representing cold-rolled galvanized steel grades with graded formability) are widely used across multiple industries. In the home appliance sector, they are applied to manufacture outer casings and internal structural parts of refrigerators, washing machines, and air conditioners—with SPCC for basic components, SPCD/SPCE for parts requiring bending/forming, and SPCG for high-precision parts. In the automotive industry, they serve as materials for non-load-bearing components like car body trim, door inner panels, and instrument panel brackets, where higher-formability SPCD/SPCE meet complex shaping needs. In furniture manufacturing, they are used to produce metal cabinet frames, drawer slides, and office furniture supports, leveraging their corrosion resistance and easy machining. In the light industrial and packaging fields, they are adopted for making metal packaging boxes, small household hardware, and decorative metal panels. Additionally, they find use in municipal infrastructure for small decorative parts of public facilities and in electronic equipment for chassis brackets, with the specific grade selected based on requirements for formability, surface finish, and precision.
