High tensile steel plates are the backbone of modern construction, offering the perfect mix of strength, reliability, and economy. From bridges to buildings, these plates reduce steel consumption, increase load capacity, and improve safety. Hindustan Steel Corporation supplies these plates in E350, E450, S355J2, S420NL, and more — cut-to-size and mill-certified.
What Are High Tensile Steel Plates Used for in Construction?
In large-scale construction projects, weight-saving and strength are key. High tensile plates are used for:
- Heavy-duty building columns and beams
- Bridge girders and expansion joints
- Crane supports and formwork structures
- Machine foundations
- Retaining walls and high-load platforms
These plates help increase structural lifespan, reduce welding joints, and improve fabrication timelines.
Structural Advantages in Heavy Civil Projects
| Benefit | Impact on Construction |
|---|---|
| Higher strength-to-weight ratio | Less steel needed for same load bearing |
| Better weldability | Faster on-site fabrication |
| High impact resistance | Safer for seismic and high-load zones |
| Long product life | Lower maintenance and lifecycle costs |
S355J2 and E450 are often specified in infrastructure tenders for their mechanical reliability and standard compliance.
Grades Commonly Used in Construction
At Hindustan Steel, we supply the following grades tailored for construction:
- IS 2062 E350 / E450 – Indian Standard for civil use
- EN 10025 S355J2 / S420NL – For bridges, load-bearing decks
- ASTM A572 Gr 50 / A573 – For global infra projects
- SAILMA & JFE Hiten – For ultra-strength requirements
We offer these plates in as-rolled, normalized, and Q+T conditions, based on the grade and application.
Which Standards Are Followed for Construction Plates?
Construction projects demand plates that follow:
- IS 2062, EN 10025, ASTM A572, A573
- CE / PED for export
Charpy Impact Testing (for bridges and seismic zones)
We provide 3.1/3.2 mill TC, UT reports, and project-specific heat numbers.
Sizes & Thickness for Construction Site Use
We stock and cut high tensile plates in:
- Thickness: 5mm to 120mm
- Width: Up to 3000mm
- Length: Up to 12,000mm
Custom CNC shapes for base plates, gussets, web plates
We also supply ready-drilled, beveled, or sandblasted plates.
Weldability & Fabrication Properties
Grades like E350 and S355J2 offer excellent weldability using:
- Manual/MIG/TIG welding
- Plasma and oxy-fuel cutting
- CNC drilling and beveling
E450 and higher may require preheat or controlled cooling during fabrication. We support weld procedure qualification records (WPQR) for infra EPCs.
Top 5 Use Cases in Construction (with Buyer Benefits)
| Use Case | Buyer Benefit |
|---|---|
| Bridge Girders & Box Sections | High impact strength + weather resistance |
| Building Columns & Beams | High load support with lower steel usage |
| Heavy Machinery Foundations | Crack resistance under load & vibration |
| Crane Runways & Lifting Bays | High fatigue resistance |
| Retaining Walls & Tunnel Supports | Excellent buckling and pressure control |

- Europe: France, Poland, Germany
Plates are packed in ISPM-certified wooden pallets with custom markings and seaworthy coatings.
How to Choose the Right Grade for Your Project?
- Check drawing load conditions and impact spec
- Consider weldability and preheat restrictions
- Ensure standard compliance for EPC or government contracts
- Ask for equivalent mapping if tender mentions EN or ASTM grades
We help buyers match grades, optimize weight-to-strength ratio, and reduce plate wastage.
Certifications and Mill Reports Available
- EN 10204 3.1 / 3.2
- CE Marking for bridges & EU use
- UT / Charpy at -20°C (J2 grade)
- ISO / IBR / PED on request
- Shot-blasted + primer-coated plates for ready site use
All documentation is digitally traceable and compliant with infra EPC documentation workflows.
FAQs Top 5 Uses of High Tensile Plates in Construction Industry
Are E350 plates used in buildings?
Yes, for columns, bracing, and floor supports in mid-rise and commercial buildings.
What thickness of plates is used for base plates?
Commonly 20mm to 60mm depending on the structure and anchoring system.
Can I get construction steel plates cut to drawing?
Yes — we offer CNC cutting as per your DWG/DXF files.
Are these plates available with UT and impact test?
Yes — we provide UT-tested and Charpy-certified plates for bridge and infra use
Do you supply plates with CE and PED marking?
Yes, for European export orders or EN-standard-compliant tenders.
Can I get primer coating on the plate?
Yes — we offer shot blasting and red-oxide/primer coating for site-readiness.
Do these plates rust?
If untreated, yes. We recommend primer coating or galvanization post-weld
What is the weight of an E350 20mm thick plate?
~157 kg per square meter (20mm × 7850 kg/m³ density)
Which Indian mills produce high tensile plates?
SAIL, JSPL, Essar, and imported plates like JFE Hiten are common.
Can I use S355J2 instead of E350?
Yes, if your project demands EN compliance — it’s equivalent in strength.
What is the lead time for civil-grade plates?
2–5 working days for stock sizes; custom profiles may take 7–10 days.
Do you deliver to construction sites directly?
Yes — pan-India site delivery + full documentation provided
Can high tensile plates be bent?
Yes — E350 and S355J2 have good bendability. E450 may need more care
