SPCC/SPCD/SPCE/SPCG galvanized sheets (cold-rolled galvanized steel grades compliant with JIS G3141, with graded formability) are widely used in home appliance sector for refrigerators/washing machines casings and internal parts—SPCC for basic components, SPCD/SPCE for bendable/formed parts, SPCG for high-precision parts; applied in automotive industry for non-load-bearing parts like car body trim and door inner panels, with SPCD/SPCE meeting complex shaping needs; used in furniture manufacturing for metal cabinet frames and drawer slides, leveraging corrosion resistance and machinability; adopted in light industry/packaging for metal boxes, small hardware and decorative panels; and applied in municipal infrastructure for public facility decorative parts and electronic equipment for chassis brackets, with specific grades selected based on formability, surface finish and precision requirements.
