BS 4211 Cage Ladder Requirements
UK projects are compliance-gated by BS 4211 plus the PUWER/HSE context. We build to the standard and ship the UK documentation that proves it.

|---|---|
| Fixed ladder design | Rung Φ20 mm at 280 mm spacing, 500 mm clear width |
| Cage / hoops | Cage Φ700 mm, hoops 40×5 mm @1500 mm, straps 30×3 mm |
| Cage start height | 2.2 m above access level |
| Load rating | 1.5 kN per rung |
| Galvanizing | HDG 85–100 μm per ISO 1461 |
| Materials | Q235B HDG · SS304 optional |
UK Compliance Docs — Included
British buyers do not have time to chase certificates. Every BS 4211 cage ladder ships with a DoC, a BS 4211:2005 conformity statement and MTC 3.1 material certificates — your handover file is complete from day one.
- BS 4211:2005 conformity statement
Standard-by-standard compliance in writing
- DoC per project
Declaration of Conformity for your records
- MTC 3.1 material certificates
EN 10204 3.1 for Q235B / HDG / SS304
BS 4211 Ladder Cage Options
BS 4211 Ladder Cage Options
Material choice, full-height cages, and engineered parameters built to BS 4211:2005.
Hot-Dip Galvanized
Q235B with HDG 85–100 μm per ISO 1461. Best all-round value for UK outdoor and industrial use.
Stainless SS304
PMI-tested for chemical, coastal and food-grade environments. Acid-pickled and passivated.
Full-Height Cages
Single-run cages up to 25 m (one-piece sections to 14 m), multi-run with rest platforms beyond that. Widths and walk-throughs to your drawing.

Write These Lines Into Your Spec
The BS 4211 Compliance Procurement Checklist
UK works are dual-track — BS 4211 remains the domestic route while EN ISO 14122-4 is the European one — so vague lines like "cage ladder to relevant standards" invite the cheapest interpretation. Copy these clause rows into your RFQ; every supplier must answer against the same numbers, and non-answers eliminate themselves.
| Clause Line for Your Specification | Why the Line Must Be Explicit | Our Answer |
|---|---|---|
| Rungs of circular section 250–300 mm spacing per BS 4211 | "suitable rungs" lets a supplier ship flat bar at 350 mm — rejected at handover | rung Φ20 mm at 280 mm, squarely mid-band |
| Rung load rating 1.5 kN stated with test evidence | the number only counts if it is documented, not claimed on a datasheet | 1.5 kN per rung with the load case in the structural calculation sheet |
| Cage internal width 0.6–0.8 m declared on the drawing | cages under 0.6 m snag shoulders and harnesses; over 0.8 m the cage loses its function | cage Φ700 mm — inside the band with margin for clothing and equipment |
| Standard referenced by name and date: BS 4211:2005+A1 or EN ISO 14122-4:2016 | the two tracks differ in geometry — a DoC to the wrong one fails the CDM file review | DoC issued to the standard you name; dual-track builds quoted on request |
| Hot-dip galvanized to ISO 1461 with coating certificates | painted ladders pass day one and fail year three of a maintenance contract | HDG 85–100 μm, certificate retained 10 years |
| MTC 3.1 to EN 10204 for all structural steel | UK principal designers increasingly require traceability at design-gate | MTC 3.1 for Q235B, HDG batches and SS304 where specified |

Repair or Replace — Decide Before You Buy
UK Ladder Decision Table: Repair, Retrofit or Replace
Most UK sites inherit their ladders. The question at inspection is never abstract — it is whether the asset in front of the inspector can be brought into BS 4211 compliance or must leave. Use the situation rows below, then ask for the matching quote.
| Asset Condition | The Rule of Thumb | Our Supply |
|---|---|---|
| Sound stringers and rungs, coating failing only | geometry still compliant — repair the corrosion budget, not the ladder | strip-and-regalvanize route or replacement HDG ladder at $95 per metre level pricing |
| Rungs corroded through section, spacing drifted | piecemeal rung replacement never restores the 250–300 mm band — replace | new BS 4211 ladder, rung Φ20 at 280 mm, crane-ready sections |
| Sound ladder, cage missing or deformed | retrofit the cage; the ladder geometry survives | cage modules built to the measured stringer geometry, hoops 40×5 at 1500 mm |
| Cage present but under 0.6 m internal width | out of band — opening it up is welding fiction; replace the cage | cage Φ700 mm module set, trial-assembled before dispatch |
| Weld failures at stringer connections | a new weld over an old crack is a documented liability — replace the assembly | complete ladder-cage unit with ISO 5817 grade C weld evidence |
| Whole-site renewal, 10+ ladders | standardized geometry beats one-off repairs at this scale | volume pricing at 10 and 50-plus units, one DoC set, itemized per line |
Photograph the worst three rungs and the cage top — send them with the climb height and we return the repair-or-replace verdict with pricing inside 24 hours.
Feature — Advantage — Your Outcome
What a BS 4211 Build From Us Actually Buys You
Five engineering lines, each traceable to a document your UK file review will ask for.
| Feature | Advantage | Your Outcome |
|---|---|---|
| DoC to your named standard | BS 4211 or EN ISO 14122-4, your choice on the form | CDM file review passes without document chasing |
| Cage internal width Φ700 mm | inside the 0.6–0.8 m band with margin | no snag point for shoulders, harness or tools |
| 1.5 kN rung rating, documented | load case in the engineer-signed calc sheet | inspection answer on paper, not on a datasheet claim |
| Trial assembly before dispatch | bolts proven to align at bench, not at height | install day stays a half-day, not a rework week |
| QC evidence chain kept 10 years | MTC 3.1 to ISO 5817 C to ISO 1461 to photos | liability defence long after the invoice is forgotten |
