Hot Rolled Coil is a basic carbon‑steel coil produced from continuous‑casting slab, rolled continuously above metal recrystallization temperature through rough rolling & finish rolling, laminar‑cooled and coiled. Hot Rolled Coil features good plasticity, stable weldability, strong stamping & cold‑bending capacity and economical overall cost with uniform mechanical properties. It serves as the most important basic steel raw material for steel‑structure manufacturing, mechanical processing, welded pipe production, cold rolling deep processing and infrastructure components. Hot Rolled Coil is mainly divided intoHot Rolled Steel Coil and Pickled Hot Rolled Coil. Different grades and processes of Hot Rolled Coil adapt to steel‑structure workshops, guardrail supports, welded steel pipes, mechanical stamping parts, cold‑rolling raw materials, engineering‑machinery accessories, bridge auxiliary components and other working conditions. With complete grades & specifications and full original‑mill quality certificates available, Hot Rolled Coil supports flattening & shearing, slitting, pickling & oiling, surface grinding and fixed‑length plate deep‑processing services. As‑rolled black‑scale Hot Rolled Steel Coil delivers prominent cost‑performance, being the most widely‑used Hot Rolled Coil in market, widely adopted in steel‑structure, welded‑pipe and ordinary stamping projects. Treated by pickling to remove scale and oil‑protected, Pickled Hot Rolled Coil owns clean surface, suitable for mechanical processing and stamping parts requiring decent appearance. Conventional thickness of Hot Rolled Coil ranges 1.5‑25mm, width 600‑2000mm, coil weight 3‑25 tons. Main grades include Q235B, Q355B, SS400, S235JR, S355JR, SPHC, A36. Delivered in as‑rolled black or pickled‑oiled condition. Every coil passes full inspection of mechanical property, surface appearance and dimensional tolerance. AllHot Rolled Coil comply with GB/T3274, GB/T709 national standards as well as EN10025, ASTM A36, JIS G3101 foreign‑trade standards. Enterprises for steel‑structure, machinery manufacturing and pipe processing can select Hot Rolled Steel Coil and Pickled Hot Rolled Coil according to processing method, service condition and surface requirement, giving full play to advantages of good plasticity, easy processing, large‑volume supply and controllable cost of Hot Rolled Coil and ensuring stable production of various manufacturing projects.
