Structural Types & Formats

Heavy Infrastructure Hot Rolled Steel Plates

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.

Precision & Aesthetics Cold Rolled Metal Sheets

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.

Extreme Pressure Boiler Quality Plates

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.

Safety Flooring Chequered Tread Plates

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.

Performance Features & Applications

Absolute Flatness

Advanced tension-leveling technology ensures sheets and plates are perfectly flat, critical for automated laser cutting and precision fabrication.

Exceptional Weldability

Optimized carbon equivalents in our plates ensure reliable, crack-free welding during the construction of pressure vessels and frameworks.

Internal Soundness

Rigorous ultrasonic testing guarantees our heavy plates are completely free of internal laminations, voids, and impurities.

Primary Industrial Applications

Pressure Vessels & Boilers
Shipbuilding & Marine
Architectural Facades
Oil & Gas Storage Tanks
Food & Dairy Processing
Automotive & Transport
