Structural Types & Formats
Hot Rolled (HR) Plates
Thick, heavy-duty plates processed at high temperatures. Essential for heavy load-bearing applications including shipbuilding, bridges, structural framework, and massive storage tanks.
Cold Rolled (CR) Sheets
Processed at room temperature to achieve exact dimensional tolerances and exceptionally smooth surface finishes. Ideal for automotive panels, home appliances, and architectural facades.
Boiler Quality (BQ) Plates
Engineered with exceptional notch toughness and weldability. Specifically manufactured (SA516 Gr 60/70) to contain high-pressure industrial gases and liquids in extreme thermal environments.
Chequered / Tread Plates
Features a raised diamond or tear-drop pattern on one side. Provides vital anti-slip friction for industrial walkways, stair treads, loading docks, and heavy vehicle flooring.
