What Thickness Range Is Available in Carbon Steel Plates?
Short Answer:
At Hindustan Steel Corporation, we supply carbon steel plates ranging from 6 mm to 150 mm thickness, covering most structural, fabrication, and pressure vessel needs.
Thin plates: 6 mm to 25 mm
Medium plates: 25 mm to 60 mm
Heavy plates: 60 mm to 150 mm
For special projects, custom thicknesses beyond 150 mm can be supplied on order or from mill stock.

Can You Supply Custom Cut-to-Size Thickness?
Yes, we provide CNC cut-to-size plates as per client’s thickness and dimension requirements, with tight tolerance control.
Impact of Thickness on Plate Weight
Thicker plates naturally mean higher weight per square meter, impacting
- Shipping cost
- Handling at site
- Fabrication methods (cutting, welding)
We provide a thickness-wise weight chart with every order.
Thickness Tolerances We Follow
As per relevant standards (ASTM/IS/EN/JIS)
Typical Thickness Tolerances:
| Plate Thickness | Tolerance |
|---|---|
| 6–20 mm | ±0.5 mm |
| 20–40 mm | ±0.8 mm |
| Above 40 mm | ±1.2 mm |
Custom tighter tolerances available on request.
Export of Various Thicknesses
