What Are Structural Steel Plates Used For?
Structural steel plates are flat-rolled steel sheets specifically engineered to provide high strength, ductility, and weldability for load-bearing, fabricated, and structural applications. These plates are widely used in the construction of buildings, bridges, towers, ships, and industrial plants where structural integrity is critical.
At Hindustan Steel Corporation, we supply IS 2062, ASTM A36, EN 10025 S275/S355, and SAILMA grades in cut-to-size, ready-to-fabricate condition—helping our buyers in civil, mechanical, and offshore industries.
Common Applications of Structural Steel Plates Across Industries
Structural steel plates are used in:
- Building Construction: Columns, beams, trusses, and floor systems
- Bridge Engineering: Girders, decks, stiffeners, and diaphragms
- Warehouses & PEBs: Shed columns, rafters, bracing
- Industrial Fabrication: Machinery frames, pressure components, base plates
- Shipbuilding & Marine: Hulls, decks, bulkheads
- Power Plants: Support structures, turbine platforms
- Telecom & Transmission Towers: Lattice arms, tower legs
- Road & Metro Projects: Retaining walls, formwork, crash barriers
Structural vs Boiler vs High Tensile Plates – What’s the Difference?
| Plate Type | Strength | Usage |
|---|---|---|
| Structural Plate | Medium-High | Buildings, bridges, towers |
| Boiler Plate | Moderate | Pressure vessels, tanks, steam lines |
| High Tensile Plate | Very High | Cranes, trailers, off-road structures |
Structural plates prioritize formability + strength while maintaining cost-efficiency.
Typical Mechanical & Chemical Properties of Structural Steel Plates
| Property | Typical Range |
|---|---|
| Yield Strength | 250–450 MPa (varies by grade) |
| Tensile Strength | 410–700 MPa |
| Elongation | 20–28% |
| Carbon Content | 0.2–0.25% |
| Weldability | Excellent (Low carbon) |
Grades like IS 2062 E250/E350, S355J2, and A36 offer balanced strength and ductility for most steel frameworks.
