Product Description

VIDEO

Q235B hot rolled carbon steel coil is produced by hot rolling process, with good strength, plasticity and welding performance. Q235B is a common low carbon steel, belonging to the carbon structural steel in the Chinese standard GB/T 700. It is widely used in buildings, bridges, vehicles, ships and other structural engineering.

Characteristics of Q235B Steel

Good Plasticity: Easily processed and formed, suitable for complex structural components. Excellent Weldability: Minimizes the risk of cracks during welding, making it ideal for various connection methods. Moderate Strength: Provides adequate tensile and yield strength for construction and engineering needs. Significant Ductility: Can elongate under stress without breaking, ideal for manufacturing structural parts. Versatile Applications: Widely used in construction, bridges, shipbuilding, vehicle manufacturing, and tool making.
