S235JR carbon steel coil is produced to EU EN 10025-2 standard via high-temperature hot rolling, continuous casting, pickling, leveling and coiling without complex heat treatment. It features good plasticity, toughness and weldability, easy cutting and forming with stable mechanical properties and low cost. It is widely used for light steel structures, building brackets, guardrails, general stamping & welded parts and civil engineering components under indoor normal temperature conditions.

Compliant with EN 10025-2, S275JR carbon steel coil is manufactured by hot rolling with optimized chemical composition, followed by smelting, continuous rolling, online leveling, pickling and coiling. It delivers higher yield strength than S235JR while retaining good weldability and processability, featuring strong bearing capacity and balanced performance. It is commonly made into steel beams, columns, load-bearing brackets, mechanical frames, agricultural machinery parts and medium-load welded structural parts for factories and bridge auxiliary structures.

S355JR carbon steel coil is produced under EN 10025-2 using controlled hot rolling and cooling technology to refine grain structure after smelting, rolling, inspection and coiling. As a high-strength structural steel, it has high tensile strength, excellent impact resistance and good weldability, which helps reduce material thickness and cut engineering costs. It is suitable for heavy machinery, large steel structures, bridges, crane components, mining equipment and high-rise load-bearing steel parts.

ASTM A36 carbon steel coil is manufactured to ASTM A36/A36M standard through converter or electric furnace smelting, continuous hot rolling, pickling and automatic coiling with strict chemical and mechanical control. It boasts outstanding weldability, ductility and machinability, stable strength and sufficient supply. This versatile steel is widely used for building steel frames, trusses, mechanical housings, pipeline supports, municipal facilities and general civil & industrial structural projects.

A572 Gr50 carbon steel coil is a high-strength low-alloy steel conforming to ASTM A572, produced by adding trace alloy elements plus controlled rolling and accelerated cooling, with smelting, NDT inspection and stress relief. It features high yield strength, light weight, good fatigue resistance and weldability, helping lower structural self-weight. It is ideal for automobile frames, chassis parts, construction machinery, bridge steelwork, high-rise load-bearing components, storage tanks and large-span steel structures.

A1011 CS Type B carbon steel coil is made per ASTM A1011/A1011M from ultra-low carbon steel via fine smelting, low-temperature hot rolling, leveling and surface finishing with tight control of flatness and internal stress. It has superb deep drawing & stamping performance, high ductility and smooth surface, resisting cracking during complex forming. It is widely used for auto sheet metal, home appliance shells, electrical casings, hardware stampings and thin-wall precision formed parts.
