When buyers compare stainless steel they usually argue about grade — 202 vs 304 vs 316 — and forget the finish. But the finish decides how the surface looks, how easy it is to keep clean, and a real chunk of the ₹/kg you pay. Here's what the common finishes mean and where each one belongs.
Why finish matters (not just grade)
The grade decides corrosion resistance; the finish decides appearance, hygiene and processing cost. The same 304 sheet can leave the mill as a dull 2B or be polished up to a mirror — same steel, very different look and price. Pick the finish for the job, then make sure the grade suits the environment.
The common finishes, mill to mirror
| Finish | What it is | Look | Typical use | Cost |
|---|---|---|---|---|
| 2B (mill) | Cold-rolled, annealed, pickled, skin-passed | Smooth, low-gloss grey | Tanks, general fabrication, base for further polishing | ₹ |
| BA | Bright annealed | Bright, reflective | Appliances, trim, mild decorative | ₹₹ |
| No.4 brushed | Abrasive-belt brushed (~150–180 grit) | Uniform fine satin lines | Kitchens, lifts, façades, railings | ₹₹ |
| Hairline | Long, fine continuous brush lines | Subtle premium satin | Architecture, interiors, signage | ₹₹ |
| No.8 mirror | Progressively polished to fully reflective | Mirror, near-chrome | Decorative panels, lobbies, temples | ₹₹₹ |
| PVD coated | Vacuum-deposited colour over a polished base | Gold, rose gold, black, bronze | Hospitality, retail, luxury interiors | ₹₹₹+ |
Choosing a finish for the job
- Kitchen, dairy, hygiene — No.4 brushed: easy to clean, hides minor scratches.
- Architecture & interiors — hairline or No.4 for a calm, premium satin look.
- Decorative & luxury — No.8 mirror or PVD colour for feature panels and façades.
- Structural or hidden work — 2B is fine and cheapest; don't pay for polish you won't see.
- Outdoor or coastal — choose the grade first (316/316L), then the finish.
How finish affects the ₹/kg price
Every polishing step is processing cost on top of the base 2B rate. BA and No.4 add a moderate premium; No.8 mirror adds more because it is multi-stage polishing; PVD adds the most because it is a coated, vacuum-deposited process. If budget is tight and looks don't matter, 2B is the value choice.
Finish and grade go together
A finish does not change corrosion resistance — that is the grade's job. A mirror-polished 202 panel will still corrode outdoors near the coast; a 2B 316 sheet will outlast it. Decide the grade for the environment and the finish for the look, and don't let a shiny surface talk you into the wrong grade.

Quick answers
What is the difference between 2B and No.4 finish?
2B is the standard smooth, low-gloss mill finish — cold-rolled, annealed and skin-passed. No.4 is a brushed satin finish made by belt-grinding the surface to fine uniform lines; it looks more premium and is common on kitchens, lifts and façades, at a higher ₹/kg than 2B.
Is a No.8 mirror finish more corrosion resistant?
Only marginally — a smoother surface holds less dirt and moisture, which helps a little, but corrosion resistance is set by the grade (304 vs 316), not the polish. For corrosive or coastal use, upgrade the grade, not just the finish.
What is PVD coated stainless steel?
PVD (physical vapour deposition) bonds a thin, hard coloured layer — gold, rose gold, black or bronze — onto a polished stainless sheet in a vacuum chamber. It is used for hospitality, retail and luxury interiors and carries the highest processing cost of the common finishes.
