Product Overview
SPCC carbon steel coil is a cold-rolled steel coil manufactured to the Japanese Industrial Standard JIS G 3141. The designation “SPCC” stands for Steel Plate Cold Rolled Commercial, indicating a commercial-quality cold-rolled carbon steel with excellent surface finish, precise dimensional tolerances, and good formability. SPCC coils are the foundational material for a wide range of manufacturing applications, including automotive components, home appliances, electrical enclosures, furniture, and general fabrication.
Huaxia-Steel supplies SPCC cold-rolled coils in thicknesses from 0.3 mm to 3.0 mm, widths from 600 mm to 1500 mm, and coil weights up to 25 MT. Our SPCC coils are produced by leading Chinese cold-rolling mills using advanced 6-high and 20-high rolling mills, ensuring superior surface quality (finish BA, FB, or FC), uniform thickness, and consistent mechanical properties across the entire coil length.
