Hot Rolled Carbon Steel Plate Q235B A36 SS400 S235JR MS Mild Steel Plates
Hot Rolled Carbon Steel Plate — Product Description
Product Overview
Hot rolled carbon steel plates (also known as mild steel plates or MS plates) are general-purpose structural steel plates produced by hot rolling. They are widely used in construction, machinery manufacturing, shipbuilding, and general fabrication. With excellent weldability, formability, and load-bearing capacity, carbon steel plates are one of the most versatile and cost-effective materials in the steel industry.
Available in multiple international grades including Q235B, A36, SS400, S235JR, and Q345B, our carbon steel plates meet the requirements of various global standards and are suitable for a wide range of applications.
