What Surface Finishes Are Available for Carbon Steel Plates?

When sourcing carbon steel plates for structural fabrication, pressure vessels, or OEM components, surface finish and machining condition can impact:
Weldability
Corrosion protection
Paint adhesion
Dimensional tolerance

At Hindustan Steel Corporation, we offer multiple surface finish and machining options as per client need and project specs.

Types of Surface Finishes Offered

Finish Type Description
Mill Finish (As-Rolled) Standard finish from rolling mill
Shot Blasted Removes scale and rust, improves surface cleanliness
Shot Blasted + Primer Coated Anti-corrosion primer applied post-blasting
Polished / Ground For special OEM applications
Pickled For surface oxide removal (on request)

Finish choice depends on your fabrication and corrosion protection needs.

Why Surface Finish Matters in Carbon Steel Plates

  • Better weld prep
  • Easier surface coating (primer, paint, epoxy)
  • Required for offshore/marine applications
  • Reduces site preparation time

We can customize finish based on project type: Structural, Boiler, Oil & Gas, or Shipbuilding.

Applications Requiring Special Surface Finishes

  • Bridges & Structural Steel Fabrication
  • Boiler Shells & Pressure Vessels
  • Shipbuilding & Marine Projects
  • OEM Machine Frames
  • Oil & Gas Fabrication Yards

Surface Finish Standards Followed

Standard Surface Finish Description
SA 2.5 (ISO 8501-1) Shot Blasted surface
Mill Tolerances As per ASTM/EN/IS standards
