High Tensile Steel Plates for Bridges & Infrastructure Projects

High Tensile Steel Plates for Bridges & Infrastructure

At Hindustan Steel Corporation, we supply structural-grade high tensile steel plates used in building India’s and the world’s most critical bridge, highway, metro, flyover, and infrastructure megaprojects. These plates are engineered for long-span load-bearing, corrosion resistance, weldability, and fatigue performance.

We stock globally approved grades from EN 10025-6, ASTM, SAILMA, and more — all suited for civil, rail, and highway engineering sectors.

Applications in Bridge & Infrastructure Projects

These plates are used in:

  • Suspension & cable-stayed bridge decks
  • Railway & road overbridges
  • Metro station roof structures and foot-over bridges (FOBs)
  • Girders, beams, columns, arches, cantilevers
  • Flyovers, underpasses, trusses, and viaducts
  • Flood barrier walls, noise barriers, retaining walls

Also preferred in airport hangars, stadium structures, tower pylons, and telecom infrastructure.

Mechanical Properties for Structural Use

  • Yield Strength: 275 MPa to 690 MPa
  • Tensile Strength: 410 MPa to 890 MPa
  • Elongation: ≥ 14–20%
  • Impact Resistance: 27J – 50J at -20°C / -40°C
  • Weldability: Excellent across all grades
  • Low Temperature Performance: Required for hilly, sub-zero zones

Chemical Composition – Structural Bridge Grades

Typical alloy elements include:

  • Carbon (C): 0.14–0.22%
  • Manganese (Mn): 1.0–1.6%
  • Silicon (Si): 0.2–0.5%
  • Niobium / Vanadium / Titanium – for grain refinement and strength
  • Low S/P: For clean welds and high toughness

Plates comply with CE (Carbon Equivalent) limits for easy fabrication.

Structural Plate Grades & Global Standards

We supply:

  • EN 10025-2 S275JR / S355J2 / S420NL / S460N
  • EN 10025-6 S690QL / S890QL (for heavy-load bridge girders)
  • IS 2062 E250BR / E350BR / E450BR
  • SAILMA 350 / 410 / 450 / 550
  • ASTM A572 Gr. 50 / 60 / 65
  • JIS / DIN / BS / NFA equivalents for global tenders

All grades come with UT test reports, low temperature guarantees, and structural weld test compliance.

Sizes & Profiles for Bridge Construction

  1. Thickness: 6 mm – 120 mm
  2. Width: Up to 3000 mm
  3. Length: Up to 12 meters
  4. Shapes: Rectangular, taper-cut, cambered, profile-cut beams
  5. Tolerances: As per EN 10029 Class A/B/C

Plates can be custom-cut for box girders, I-beams, truss panels, or cantilever assemblies.

Heat Treatment & Service Life Expectations

  • Normalized, Q&T, or TMCP plates available based on bridge design load
  • Resistance to:
    • Cyclic fatigue
    • Saltwater corrosion
    • Expansion & contraction under thermal loads
  • Service life expectancy: 25–100 years depending on coating + maintenance

Fabrication, Bending & Welding Guidelines

  • Welding: CE < 0.45% for preheat-free welding (thin plates)
  • Bending: S355/S420 allow cold bending for curved designs
  • Bolting & Machining: Good dimensional stability and hardness
  • Galvanizing / Shot-blasting / Painting: Available as value-added services

All grades are bridge-fabricator certified with full weld traceability.

  • All deliveries with numbered plates, side stamping, export wrapping, and BOL-compliant documents

Buyer Tips – How to Choose Structural Plate Grade

Structure Type Recommended Plate
Road/Flyover Bridge S355J2 / E350BR / A572-50
Railway Overbridge (ROB) S420NL / SAILMA 410
Cable-Stayed Bridge Deck S460NL / S690QL
Trusses & Beams EN 10025-2 / TMCP grades
Girders Weldox 700 / Dillimax

Ask us to match bridge design drawings with equivalent grades based on load, fatigue, and seismic criteria.
