SS304 Cat Ladder vs SS316 Cat Ladder
SS304 Cat Ladder vs SS316 Cat Ladder — Choose the Right Grade
The right stainless grade is a function of the atmosphere it will live in. We build SS304 cat ladders as standard and upgrade to SS316 wherever chlorides, salt or chemicals are present — both mill-certified so the grade on the certificate matches the ladder in your plant. A material mismatch near coastal or chemical exposure turns a capital asset into a maintenance line item.
- SS304 (1.4301) — 18% chromium, 8% nickel
Roof access, industrial atmospheres, food & beverage and cleanroom duty
- SS316 (1.4401) — adds ~2% molybdenum
Marine, coastal, chemical and chlorine-exposed environments
- HDG Q235B for budget interiors
Hot-dip galvanized steel, ISO 1461, where stainless is not required
- Traceable to heat
MTC 3.1 material certificate (EN 10204) ships with every stainless order
| Grade | Corrosion Resistance | Best-Fit Environments | Typical Use |
|---|---|---|---|
| SS304 (1.4301) | Excellent for normal atmospheres; resists oxidation up to 870 °C | Urban roofs, industrial plants, food & beverage | Standard SS304 cat ladder with or without cage |
| SS316 (1.4401) | Superior pitting resistance from molybdenum; chloride-resistant | Coastal, marine, chemical, chlorine & brine exposure | SS316 cat ladder, safety gate and cage upgrade |
| HDG Q235B | Sacrificial zinc layer 85–100 µm per ISO 1461 | Interior roof rooms and sheltered steel structures | Economy steel cat ladders where stainless is not needed |

Custom Cat Ladders, Built to Your Heights
Tell us the top landing height and stile spacing — we produce the SS304 cat ladder in one continuous run up to 25 m, with rest platforms and offset brackets as the layout requires.
Stainless With Cage & Gate
Add a stainless safety cage and a self-closing safety gate — all welds passivated in the same grade, so there is no galvanic mismatch between ladder and cage.
SS316 Upgrade for Marine Duty
For offshore, coastal and chemical sites we switch the complete assembly — rungs, stiles, cage and gate — to SS316 verification.
Grade-Matched Fixings
SS304 anchor bolts and standoff brackets shipped with the ladder, trial-assembled at the factory so nothing needs rework on site.
