Home > Our Products > Quenched and Tempered Plates > Application > Quenched & Tempered Steel Plates for Bridges and Structural Engineering
When it comes to bridges, flyovers, heavy structures, and load-bearing installations — failure is not an option. That’s why engineers across the world turn to Q&T (Quenched and Tempered) steel plates for critical strength, fatigue resistance, and long-term performance.
At Hindustan Steel Corporation, we supply premium-grade Q&T plates from global mills and Indian brands like:
These plates are engineered for structural integrity in bridges, frames, towers, and high-load modular construction.
Q&T steel plates are ideal for:
Infrastructure Applications
These plates offer high strength-to-weight ratio, making them perfect for long spans, lighter supports, and reduced column load.
Q&T plates used in structural and bridge projects are optimized for strength and fatigue life:
| Property | Typical Range |
| Yield Strength | 690 – 1100 MPa |
| Tensile Strength | 770 – 1350 MPa |
| Elongation | 12–15% |
| Impact Resistance | ≥47J at -20°C / -40°C |
| Thickness | 6 mm – 150 mm |
These mechanical traits allow for slimmer bridge decks, longer unsupported spans, and lighter modular units with superior safety
We help bridge design firms and EPC contractors select steel plates based on:
| Use Case | Recommended Grades |
| Girder and deck components | Dillimax 690T / S690QL / A514 Gr B |
| Cantilever or truss assemblies | S890QL / HITEN 980LE / Strenx 900 |
| Earthquake-resistant structures | S960QL / HIND HARD 600 / A517 F |
| Lightweight bridge segments | Strenx 960 / Dillimax 890T |
| Budget-based heavy structures | HIND HARD 500 / EN 10025-6 S690QL |
All grades are available with cutting, machining, welding guidance, and mill documentation
We supply plates that comply with major global structural steel standards to ensure your project meets design codes
| Standard | Common Grades Supplied | Applications |
| EN 10025-6 | S690QL / S890QL / S960QL | Bridge decks, box girders, arch supports |
| ASTM A514 / A517 | Grade B, F, Q | Trusses, towers, seismic frames |
| JIS G 3128 / G 3140 | HITEN 780LE / 980LE | Column-base structures, bridge plates |
| Dillinger Standards | Dillimax 690T / 890T / 965T | Long-span bridges and modular beams |
| SSAB High Strength | Strenx 700 / 900 / 960 | Prefab bridge modules, light-weight girders |
Plates are provided with MTC (EN 10204 3.1/3.2) for approval in infrastructure projects worldwide.
We stock and cut Q&T plates used in structural and bridge manufacturing:
Common Sizes:

Why project buyers choose us:
Whether it’s a long-span flyover or seismic steel tower — our plates deliver confidence under load.
Sometimes, an equivalent or hybrid grade may offer better economics or faster lead times.
| Use Case | Alternative Grades |
| Long-span bridges (low-weight) | Strenx 960, Dillimax 890T |
| Budget prefab bridges | S690QL / A514 Gr B |
| Seismic or extreme load frames | S960QL, HITEN 980LE, A517 Gr F |
| Weld-heavy girder sections | HITEN 780LE / Dillimax 690T |
| Column bases and truss joints | HIND HARD 550 / 600 (custom spec available) |
Our team supports design alignment, weld compatibility, and documentation needs across public and private infra projects
