Plate Size, Thickness & Width Chart – Structural Steel Guide

Table of Contents

When choosing structural steel plates for bridges, industrial buildings, telecom towers, or PEB sheds, accurate size selection is key to cost, strength, and speed. This page offers a complete overview of standard and custom plate sizes, widths, and thickness ranges available with Hindustan Steel Corporation. From 6 mm to 150 mm thick plates, we supply sizes that meet IS 2062, EN 10025, ASTM A36, and S355 specifications — along with profile-cut options and mill-level precision.

Whether you need bulk-sized 2500 x 12000 mm plates or precision-cut structural strips, we deliver to your project specs.

What Are Standard Structural Steel Plate Sizes?

Structural steel plates are commonly supplied in flat rectangular formats with mill edge or sheared edge finishes. Industry-standard dimensions include:

  • 2000 mm x 6000 mm
  • 2500 mm x 12000 mm
  • 1250 mm x 5000 mm
  • 3000 mm x 12000 mm

These plates can also be cut to length or width, depending on project requirements. Longer plates are preferred in bridge and offshore work, while narrower formats suit telecom and fabrication projects.

Common Thickness Range for Structural Plates

At Hindustan Steel Corporation, we offer structural steel plates in thicknesses ranging from 6 mm to 150 mm — suitable for general construction, heavy machinery, industrial floors, and structural loads.

  • 6 mm to 25 mm – Civil structures, bridges, telecom towers
  • 25 mm to 60 mm – Heavy-duty beams, columns, welded structures
  • 60 mm to 100 mm+ – Load-bearing tanks, cranes, offshore platforms

Custom thicknesses up to 200 mm are available on request for special-purpose applications.

Structural Plate Width Options for Bulk Supply

Steel plates are generally stocked in standard widths of 1000 mm, 1250 mm, 1500 mm, 2000 mm, 2500 mm, and 3000 mm, depending on mill rolling capabilities and client preference.

At Hindustan Steel Corporation, we maintain ready inventory of the following width combinations:

  • 1250 mm × 5000/6000 mm
  • 1500 mm × 6000/12000 mm
  • 2500 mm × 12000 mm
  • 3000 mm × 12000 mm (for offshore & infrastructure orders)

Custom-width slits and strips can also be produced with tolerances as per EN 10029 or IS 1852.

Standard Width (mm) Available Length (mm) Common Thickness (mm)
1250 2500 / 5000 / 6000 6 / 8 / 10 / 12 / 16 / 20
1500 3000 / 6000 / 12000 6 / 10 / 16 / 25 / 40
2000 6000 / 12000 8 / 16 / 25 / 40 / 60 / 80
2500 6000 / 12000 10 / 20 / 30 / 50 / 80 / 100
3000 12000 12 / 40 / 50 / 80 / 100 / 120

Note: We also supply intermediate sizes and custom lengths on request. For thickness above 100 mm, lead time applies.

Cut-to-Length Structural Plates – Exact Fit Every Time

We offer cut-to-length services with mill-edge or sheared edge finish for clients looking to optimize material use. You can specify:

  1. Custom lengths (e.g., 3800 mm, 9100 mm, 10200 mm)
  2. Custom widths (e.g., 1400 mm, 2150 mm, 2900 mm)
  3. Tighter tolerances (as per EN 10029 Class B, C, or D)

This helps reduce site cutting, labor, and scrap — increasing your project efficiency.

Width & Thickness Tolerances – EN, ASTM, IS Standard

We comply with EN 10029, IS 1852, and ASTM A6/A20 tolerance norms for flatness, thickness, and width. Typical tolerances include:

  • Width tolerance: ±10 mm (standard), ±5 mm (custom)
  • Length tolerance: ±20 mm
  • Thickness tolerance: +0.3 mm / -0.0 mm up to 40 mm
  • Flatness tolerance: 5 mm/m standard; improved flatness available

Profile-Cut Steel Plates for Fabrication & Pre-Fitment

For structural fabricators, we offer profile cutting (oxyfuel, plasma, laser) as per your drawings. Pre-cut profiles reduce fabrication time and ensure accuracy.

Popular profile services include:

  • Gusset plates
  • Web/flange cutouts
  • Bolt hole patterns
  • Weld-ready edge prep

Drawings can be supplied in DXF, DWG, or PDF formats.

Customization for Bridge, Telecom & Marine Projects

Depending on the project (e.g., telecom towers vs. marine decks), we customize plates to meet load-bearing and corrosion-resistance requirements. Our mill partners provide:

  • Blasted + Primed finish (Sa2.5 / Sa3)
  • Marked drilling for towers
  • CNC marking for bridge components
  • MTCs and NDT testing on demand

Buyer Guide – How to Select the Right Plate Size

When choosing a structural plate size, consider:

  • Project type – bridges need longer, thicker plates; telecom towers need narrower ones
  • Fabrication tools – match width to machine bed capacity
  • Transport limits – optimize for road or container width (e.g., <2500 mm)
  • Weldability & wastage – go for cut-to-length for less scrap

Our team helps you match specs to budgets and delivery timelines.

  • EN 10029: European grades
  • ASTM A6: American standards

Typically ±5 mm per meter is accepted, but plates can be ordered with tighter flatness as per Class A or Class S standards depending on end-use.

Choose a plate width that matches your machine bed or layout requirements. For fabrication shops, 1250 mm to 2500 mm is common for easy handling and transport.

Yes, we offer non-standard widths such as 1400 mm or 1800 mm based on stock availability or cut-to-size from wider plates. MOQ may apply.

Yes, we regularly export wide plates up to 3000 mm to UAE, Saudi Arabia, and Oman. These are ideal for bridge decks, large girders, and offshore platforms.

Our plates are available in as-rolled, shot-blasted, pickled & oiled, or primer-coated finishes depending on application and customer preference.

Yes, we can supply structural plates with red oxide primer or weldable primer coating, especially for export shipments or PEB structures.

Bridge girders typically require 25 mm to 80 mm thick plates in high-strength grades like S355J2 or E350/E450. We supply such sizes regularly.

Yes, all our structural steel plates are delivered with EN 10204 3.1 Mill Test Certificates. 3.2 certification is available on request with third-party inspection.

For in-stock material, cut-to-length or custom size plates can be dispatched within 2–4 working days. For mill-order, delivery is 2–4 weeks based on specs and volume.
