Fixed Ladder Guards
Fixed ladder guards protect the climber where a ladder breaks through a floor or meets a landing. We build them as add-ons to a new ladder or as upgrades to an existing one — always matched to your rail width.
Cage Hoop Guards
40 × 5 mm flat hoop bands welded to the rungs at Φ700 mm (≈29 in) inside diameter — the same 29-inch ID used by Cotterman, so spec for spec your guards line up with industry-standard caging.
Exit Guards
Top-of-ladder exit protection per DIN 18799-3 — a full-width guard that guides the climber onto the landing and stops falls at the exit point.
Walk-Through & Gate Guards
Guards with an integrated opening and a self-closing swing gate, with a lockable option — A-Mezz style lockable doors, built to your opening size.
Fixed Ladder Guards Specifications & Dimensions
| Guard Component | Standard Spec | Custom |
|---|---|---|
| Hoop band | 40 × 5 mm flat steel | 50 × 5 mm heavy duty |
| Hoop inside diameter | Φ700 mm (≈29 in) | Up to Φ900 mm |
| Hoop vertical spacing | 350 mm centers | Per project |
| Bottom bell mouth | Flared entry at base | Flare width per spec |
| Exit guard (top) | DIN 18799-3 pattern | Walk-through option |
| Gate-integrated guard | Self-closing swing gate | Lockable option |
| Material | Q235B / SS304 / SS316 | Per environment |
| Finish | HDG 85 – 100 μm | Pickled / painted / electropolish |
Cage hoop dimensions share the Φ700 mm (≈29 in ID) industry convention — same number as the product cage spec, so guards retrofit to Dengtai ladders and standard caged systems.

Common questions
Both — we build guards into new ladders at the factory or supply them as upgrades for an existing ladder, always matched to your rail width.
Cage hoops are spaced at 350 mm centers, welded with 40 × 5 mm flat bands at Φ700 mm (≈29 in) inside diameter.
Every guard order includes the DoC and structural calculations; guards built to OSHA 1910.23 or DIN 18799-3 exit-guard specs ship with the relevant certificate.
Yes — walk-through and gate guards come with a self-closing swing gate and a lockable option, built to your opening size.
Yes — Φ700 mm (≈29 in ID) follows the industry convention used by brands such as Cotterman, so replacement guards line up with existing caging.

Fixed Ladder Guards — Sizes, Materials & Standards
Guards close the gaps around a ladder — the cage around the climb, the exit guard at the landing, and the opening guard at floor level. Each one has a size and a standard behind it.
| Guard type | Standard size / material | Standard |
|---|---|---|
| Cage hoops (cage guard) | Φ700 mm ID, 40 × 5 mm flat steel, Q235B / SS304 / SS316 | ANSI A14.3 / BS 4211 |
| Cage vertical bars | On ≈300 mm centers, full cage height from 2.2 m | ANSI A14.3 / BS 4211 |
| Exit guard hoop | Hoop at landing level, same Φ700 mm cage line | DIN 18799-3 / OSHA 1910.23 |
| Landing opening guard | Guardrail 42″ high + self-closing gate at the opening | OSHA 1910.23 / 1910.28(b)(3) |
| Swing gate | Self-closing, built to opening width (standard 600–900 mm) | OSHA 1910.23(a)(2) / ANSI A1264.1 |
| Lockable access door | Per opening size, with slam latch or padlock hasp | Site security spec |
| Finish | HDG 85–100 µm, pickled, painted, or electropolished SS | ISO 1461 |
Guards are built with the ladder so the fit is exact — same material, same finish, same weld class (ISO 5817 C). They can also be retrofitted: send the opening or cage dimensions and we fabricate a matched guard.
Fixed Ladder Guards — FAQ
Guards are the protective elements around a ladder — cage hoops and bars, exit guard hoops, landing opening guards, and swing gates — sized to the ladder geometry.
Φ700 mm inside diameter (≈29″ ID), made from 40 × 5 mm flat steel, with vertical bars on ~300 mm centers — matching the cage standard used industry-wide.
Q235B carbon steel with HDG 85–100 µm, or stainless SS304/SS316 for corrosive environments — same material as the ladder for a matched finish.
OSHA 1910.23 and 1910.28 for openings and cages, ANSI A14.3 and BS 4211 for cage geometry, DIN 18799-3 for exit guards, ANSI A1264.1 for gates.
Yes — retrofit hoops, exit guards, and swing gates are fabricated to your measured opening and welded or bolted to the existing ladder with the same finish.
