Hot Rolled Forged Medium & Heavy Steel Plate
Hot rolled heavy plates are widely used in industries requiring high strength, durability, and precision. Thanks to advanced EAF + LF + VD refining and controlled rolling technology, these plates provide superior surface finish, internal purity, and mechanical performance. They are suitable for applications in shipbuilding, bridges, pressure vessels, and construction machinery.
The plates can be delivered in normalized, quenched & tempered, or accelerated cooling condition, depending on customer requirements.
