Hot Rolled Steel Coil

This product is a hot-rolled steel coil produced by Donghai Steel Southern China using the electric arc furnace (EAF) short-process route. Its main steel grades include carbon structural steel (e.g., Q235B), high-strength low-alloy structural steel (e.g., Q355B), and quality carbon structural steel (e.g., 45#). The production and inspection strictly comply with Chinese national standards (such as GB/T 700, GB/T 1591, GB/T 699) and refer to international standards (including ASTM A36 and EN 10025), ensuring that the chemical composition, mechanical properties, and surface quality meet all specified requirements.The hot-rolled steel coil is widely used in construction, machinery, transportation, and energy sectors. Specifically, carbon structural steel is used for reinforcing bars and lightweight steel structures; high-strength low-alloy steel is suitable for load bearing components in bridges and engineering machinery; quality carbon steel is applied to mechanical parts such as shafts and gears. Additionally, the product range also includes spring steel and electrical steel, used in automotive leaf springs and motor cores, respectively.
