Manufacturers increasingly demand steel coils that withstand high-speed stamping while maintaining surface integrity. TJYCT's carbon steel coils undergo rigorous temper rolling to achieve HRB 50-70 hardness, ideal for deep-drawn components like electrical enclosures. The galvanized variants (GI/GL) provide sacrificial protection for agricultural equipment exposed to fertilizers. For food-grade applications, our tinplate coils meet FDA compliance with chromium-free passivation. By offering JIS/EN/ASTM standard coils alongside custom widths (600-1500mm), we eliminate material waste in coil-fed production lines.
