Cold Rolled Steel Coil Standard Specifications

Cold rolled steel coils come in a wide range of standard specifications to accommodate demands across diverse industries. Key common parameters are listed below:

• Thickness: Normally ranging from 0.2 mm to 4 mm; precision-grade items feature tighter thickness tolerance control, while bespoke ultra-thin variants for special uses can reach as low as 0.015 mm.
• Width: Standard width covers 600–1500 mm, custom slitting widths available upon customer requirement.
• Coil Weight: Standard coil weight spans 3 to 20 metric tons, with 5–15 MT as the most prevalent grade balancing handling operability and production efficiency; custom coil weights from 2 to 25 MT can be processed for dedicated production lines.
• Inner Diameter (ID): Regular inner diameters are 508 mm (20 inch) and 610 mm (24 inch), compatible with most standard decoiling and processing machinery; non-standard ID such as 406 mm can be tailor-made for legacy equipment.
• Applicable Standards: Widely adopted global specifications include Japanese JIS (SPCC, SPCD), European EN (DC01, DC03) and Chinese GB (DC01, SPCC), guaranteeing uniform product quality among worldwide suppliers.
