Carbon Steel Plate – Backbone of Industrial Construction
Carbon steel plate is a flat-rolled steel product manufactured by hot rolling or cold rolling processes. With carbon as the primary alloying element (typically 0.05-0.50%), it offers an excellent balance of strength, ductility, weldability, and cost-effectiveness – making it the most widely used material in construction, machinery manufacturing, and infrastructure projects.
Key characteristics:
High strength – Tensile strength from 400-600+ MPa depending on grade
Excellent weldability – Suitable for arc welding, gas welding, and resistance welding
Good formability – Can be bent, rolled, stamped, and fabricated
Cost-effective – Most economical choice for structural applications
Available in large dimensions – Up to 3000mm width, 12000mm length
