| High Light | Q355B hot rolled carbon steel coil ，high strength low alloy steel coil ，carbon steel coil 355MPa yield | ||
The Q355B high strength low alloy hot rolled carbon steel coil is engineered for structural applications that demand a superior strength-to-weight ratio without compromising weldability. With a guaranteed minimum yield strength of 355 MPa, this HSLA coil delivers reliable load-bearing performance for heavy fabrication while allowing designers to reduce section thickness and overall steel tonnage. Each coil is produced on fully automated continuous rolling lines with advanced laminar cooling control, ensuring uniform mechanical properties across the entire strip length and width. Zhengde supplies Q355B coils in thicknesses from 1.5mm to 20mm and widths from 600mm to 2000mm, with tight dimensional tolerances that simplify downstream cutting, bending and welding operations. The material chemistry is carefully balanced with controlled micro-alloying elements such as niobium and vanadium to refine grain structure, delivering consistent impact toughness even at low service temperatures. Every heat is sampled and tested in our nationally recognized laboratory, and complete mill test certificates are issued with each shipment for full material traceability.
