Our full grades guide covers the fundamentals. This is the shorter, application-first version for quick reference on-site or while briefing a contractor.
| Application | Typical grade | Note |
|---|---|---|
| Interior railings | 304 | Standard choice for the large majority of indoor work |
| Exterior railings, inland | 304 (316 for premium) | 304 performs well for typical rain exposure |
| Coastal / poolside railings | 316 | Chloride resistance matters here |
| Elevator cladding | 304 | Indoor, low corrosion risk |
| Kitchen counters/surfaces | 304 | Food-grade standard |
| Budget interior fittings | 201 (confirm with fabricator) | Lower cost, lower corrosion margin |
This is a starting reference, not a substitute for confirming your specific project's requirement with a fabricator — environmental factors (proximity to sea, industrial exposure, cleaning chemicals) can shift the recommendation either way.
