Architectural stainless steel is specified for two reasons: it looks a particular way, and it has to still look that way after years of weather and handling. The finish choice is a maintenance decision as much as a design decision.
Choosing a finish by location
| No.4 | The workhorse. Directional grain, good at hiding minor marks, easy to re-finish on site. |
|---|---|
| Vibration / SB | Best choice for handrails and public-area cladding — the non-directional texture hides fingerprints and scuffs far better than a straight grain. |
| 8K mirror | Feature and interior applications. Exterior mirror cladding shows water spotting and needs a maintenance commitment. |
What to specify before you buy
- Sheet or coil — coil-to-coil gives better consistency on large facade runs
- Maximum panel length, which drives the machine bed length
- Whether panels need protective film applied in-line (strongly recommended)
Recommended machines
- Coil polishing lines for long-run consistency
- Sheet polishing machines for cut-to-length panel work
- Coil grinding lines where the incoming coil needs defect removal first
