Material Grades You Can Specify
Custom Stainless Steel Cage Ladder
SS304, SS316 or aluminium — full-size custom caged ladders with the material grade, finish and certificates you need.
Stainless SS304
ASTM A276/A240, acid-pickled and passivated. The default for chemical, food and general corrosive-duty plants.
Stainless SS316
Marine-grade with molybdenum for high-chloride coastal and offshore environments. PMI-tested on request.
Custom Aluminium Cage Ladder
Lightweight, corrosion-resistant option where stainless is over-specified — full-size custom available.
The Grade Decides the Decade
Stainless Grade Selection by Service Environment
Stainless fails when the grade is wrong for the atmosphere — pitted 304 in a pool hall costs more than 316 ever would. This is the table our engineers select from, with PMI proof on every batch.
| Service Environment | Grade | Finish | Watch Out For |
|---|---|---|---|
| Indoor washdown / food / pharma | SS304 | pickled, electropolish optional | chloride cleaners — go 316 if bleaching is routine |
| Coastal within ~1 km of surf | SS316 | pickled & passivated | crevice corrosion at fasteners — sealed joints spec |
| Pools / water treatment | SS316 | pickled | chloramine atmospheres above water line |
| Chemical mist / offshore-adjacent | SS316 / 316L | pickled, heavier sections | weld zones — 316L where welding is heavy |
| Architectural / visible installs | SS304 | brushed or glass-bead | teaching stains — specify finish direction |
Every batch is PMI-tested with results on the EN 10204 3.1 MTC (TISCO mill) — the paper proves the grade. Cage hoops, straps and gates fabricated from the same grade as the ladder.

Grade Changes, Priced by Stage
Change Cost Table: What a Grade or Finish Change Costs at Each Stage
On stainless builds the expensive change is the grade swap — 304 to 316 changes the material cost basis (1.8x to 2.5x over HDG). When you make that call decides whether it is a free redraw or a second mill order. The table maps the real nodes.
| Stage | Change You Bring | Cost to You |
|---|---|---|
| Environment brief and CAD (1–3 days) | any re-spec: 304 to 316 to 316L, finish class, geometry — full pivot | Free — the drawing restarts on the correct grade |
| Quote stage (24h) | grade multiplier visibility, quantity, packaging | Free — requote shows the 1.8x / 2.5x deltas line by line |
| Approved, before mill order | grade swap, section sizes, finish (pickled / brushed / electropolish) | Free — material is bought to your release, nothing stocked |
| Bars and plate cut | finish changes, uncut accessories | Difference only — no penalty on affected parts |
| Welded (TIG, pre-passivation) | add-on weldments only; grade is locked in the welds | New parts at difference plus bench hours |
| Passivated and inspected | documents only — PMI results follow the built unit | Free — cert set matches the as-built grade |
The pattern: a grade decision is free until the mill order. Bring the service environment — chloride, washdown, hygiene rules — to the first conversation and the whole table stays free.
Choosing the Material Honestly
Stainless, HDG Steel, or Aluminium: The Decision Guide
The wrong material choice is the most expensive mistake on a caged ladder — it either corrodes early or corrodes your budget. One table plus two checklists settle it by service environment, not by brochure shine.
| Service Environment | HDG Steel ($95/m) | SS304 (1.8x) | SS316 (2.5x) |
|---|---|---|---|
| Inland industrial, dry | correct choice, decades of life | over-spend | over-spend |
| Food, pharma, washdown | paint hygiene issues | correct choice | for heavy chemicals |
| Coastal, surf zone, pool | zinc consumed early | tea-staining risk | correct choice |
| Heavy weldment design | fine | fine | specify 316L |
| Repaint access over live plant | maintenance cost hidden | justify on lifecycle | justify on lifecycle |
Red flags — the material spec is wrong
- "316-grade" without PMI — unverifiable grade claims are how 304 arrives at a surf zone
- Stainless with carbon-steel cage hoops — bimetallic corrosion at every hoop joint
- Welded without passivation — un-passivated welds are the first rust site on every stainless climb
- Grade chosen by budget alone — a cheap grade at a chloride site is a full replacement in 5 years
Green lights — the spec is right
- PMI-tested batches with EN 10204 3.1 MTC — the paper proves the grade you paid for
- Whole ladder one grade — hoops, straps and rungs from the same certified material
- Pickled and passivated as standard — chromium oxide layer restored after welding
- Grade justified by environment — selection mapped to chloride, washdown or hygiene duty

Custom Stainless Value at a Glance
What a Stainless Build Buys a Corrosive Site
Five features of the custom stainless route, and the outcome each lands on your plant.
| Feature | Advantage | Your Outcome |
|---|---|---|
| PMI-tested every batch | grade proven on your EN 10204 3.1 MTC | the 316 you paid for is the 316 that arrives |
| One grade throughout | hoops, straps and rungs from the same mill lot | no bimetallic joints corroding at the cage |
| Pickled and passivated standard | weld zones restored to full corrosion resistance | rust does not start at the seams |
| Hygiene finishes available | glass-bead, brushed or electropolish | audit-clean surfaces in food and pharma zones |
| 24h quote with grade deltas | 1.8x and 2.5x tiers priced line by line | 304-vs-316 decided on figures, in a day |
