Cold Rolled Coil is high‑precision flat steel produced by multi‑pass cold rolling, annealing and skin‑pass rolling using pickled hot‑rolled coil as raw material at room temperature. Featuring precise dimensional tolerance, smooth flat surface and excellent deep‑drawing performance, Cold Rolled Coil delivers much better surface quality than hot‑rolled substrate, serving as core precision raw material for home‑appliance shells, auto spare parts, hardware products and coating substrates. Cold Rolled Coil is mainly divided into Cold Rolled Steel Coil and Cold Rolled Steel Plate. Different materials and specifications of Cold Rolled Coil adapt to home‑appliance housings, auto interior‑exterior parts, precision stamping parts, spraying substrates and cabinet enclosures. With complete material grades and sufficient stock,Cold Rolled Coil supports deep‑processing customization including leveling & shearing, slitting, oiling, film laminating and fixed‑length cutting. As coil form for convenient subsequent slitting and leveling processing with high processing flexibility, Cold Rolled Steel Coil is the most versatile Cold Rolled Coil. Produced by leveling cold‑rolled coils, Cold Rolled Steel Plate owns smooth and flat surface for direct blanking, widely used for precision sheet‑metal, cabinet chassis and decorative panels. Conventional thickness of Cold Rolled Coil ranges 0.3‑3.0mm, width 600‑1800mm, coil weight 3‑25 tons, inner diameter 508/610mm. Main grades include SPCC, SPCD, SPCE, DC01, DC03, DC04, Q195. Delivery states: annealed soft state, full‑hard state. Every coil passes mechanical property test and full dimension inspection. All Cold Rolled Coil comply with GB/T5213 national standards as well as EN10130, ASTM A1008, JIS G3141 foreign‑trade standards. Enterprises for home‑appliance, auto‑parts and hardware sheet‑metal can select Cold Rolled Steel Coil and Cold Rolled Steel Plate according to stamping grade, surface requirement and processing technology, giving full play to advantages of high precision, smooth surface and good deep‑drawing performance of Cold Rolled Coil to guarantee stable appearance and forming quality of finished products.
