When it comes to high-tensile steel plates, surface quality, flatness, and weld-ready edges can make or break fabrication timelines. Hindustan Steel Corporation supplies plates that are not just high in strength, but also ready for precise cutting, reliable welding, and superior surface appearance—reducing post-processing time and cost.
Different applications demand different finishes and prep conditions:
We tailor surface and edge finishes to industry-specific requirements, including OEM tolerances and international standards.
We offer plates in the following finishes, depending on grade and project need:
| Surface Finish Type | Description | Typical Use |
|---|---|---|
| Hot Rolled (HR) | As-rolled mill finish | Structural & infra |
| Shot Blasted + Primer Coated (SBPC) | Cleaned surface with protective red oxide layer | Offshore, bridges |
| Pickled + Oiled (P&O) | Acid-cleaned to remove scale | Auto, tanks, fabrication |
| Cold Finished (on request) | Improved flatness and tight tolerance | Precision OEM parts |
| Polished / Ground (Custom) | Machined top face | Pressure plate die |
SBPC and P&O are the most popular finishes for export projects and critical welding.
At Hindustan Steel Corporation, we supply:
Ideal for laser/plasma cutting, press brake folding, and flame cut applications.E350 / E450 – Chemical Composition (IS 2062:2022 Standard)
Whether you’re building pressure vessels or trailer chassis, edge prep is crucial for:
We offer:
| Edge Type | Available On | Purpose |
|---|---|---|
| Mill Edge | HR plates | Standard supply |
| Sheared Edge | Thin gauge, stock sizes | Clean cut |
| Bevel Cut Edge | Heavy plates | For welding groove |
| Machined Edge | CNC cut-to-size | Dimensional precision |
Bevel cuts (30° / 45° / custom) available on order for plates >12mm
Every plate is supplied with:
Weld prep plates undergo de-scaling and oil removal before dispatch.
High tensile steel grades like E350 / E450 / S355J2 / SAILMA / Hiten require special attention to HAZ properties.
Our certified plates ensure:
Full welding data available on request (PWHT recommendations, CE values, etc.)
| Grade | Welding Compatibility | Notes |
|---|---|---|
| IS 2062 E250 / E350 | Excellent | Low CE, preheat optional |
| SAILMA 410 / 550 | Very Good | Preheat above 25mm |
| S355J2 / EN10025 | Excellent | Impact tested plates |
| Weldox / NAXTRA | Good | Controlled heat input required |
| ASTM A572 Gr 50 | Excellent | MIG / TIG / SAW ready |
Welding wire / filler metal suggestions available for each grade
We offer SBPC finish plates (Shot Blasted & Primer Coated) with:
Ideal for offshore, wind energy, shipbuilding, and export-ready steel
Third-party inspection (TUV / SGS / Lloyds) is available on request for:
Inspection reports with stamping visuals sent digitally before dispatch.
| Problem | Our Solution |
|---|---|
| Rusting before arrival | Export coating or vacuum film packaging |
| Warping during weld prep | Pre-leveled, stress-relieved plates |
| Fit-up issues in jigs | CNC cut + UT-tested edges |
| Plate not welding cleanly | Mill-cleaned + P&O finished supply |
We work closely with your shop floor to ensure zero wastage and faster fit-up.
We understand how plate prep affects your cost, cycle time, and weld quality.
