Fixed Ladder Parts, Explained
Fixed Ladder Parts
Every component a fixed ladder is built from, what it does, and the real numbers behind each part.
The fixed ladder parts on every build are the side rails (stiles), the rungs, and the standoff mounting brackets. Fall protection adds a safety cage, well enclosure, or ladder safety device. Optional parts include walk-thru platforms, swing gates and rest platforms — each quoted as its own line item.
Side rails — also called stiles — are the two vertical members that carry the rungs. On our standard build they are formed steel in Q235B, SS304 or SS316, spaced to a 500 mm clear width. The stile section is chosen by height and load so the assembly stays stiff over its full run.
Rungs are the climbing steps — Φ20 mm (0.79″) on our standard build, spaced 280 mm (11″) center-to-center, and rated 1.5 kN each. They are welded to the stiles with anti-slip finish on steel, or knurled/machined on stainless and aluminum.
Standoff brackets are the steel mounts that hold the ladder away from the wall at the designed climbing clearance. Standard is an 8 mm plate bracket, bolted or welded to the structure at 1.5–2 m spacing. They are the part that makes a fixed ladder non-self-supporting — the wall carries the load through them.
A safety cage is built from Φ700 mm hoops and vertical straps, welded to the stiles. It starts at 2.2 m (7–8 ft) above the base and extends 42 in above the top landing. Hoop pitch, diameter and the base bell are set to the applicable standard and included in the structural calcs.
Common additions are a walk-thru platform and swing gate at the top, rest platforms every 50 ft on tall runs, a well enclosure, and a ladder safety device for PFAS-style fall protection. All are fabricated in the same factory and quoted on the same itemized basis as the ladder itself.
Yes. Rungs, standoff brackets, cage hoops, verticals and gates are available as spares to match existing Dengtai ladders. Send the drawing or model number and we quote replacement parts in 24 hours, shipped with the same MTC 3.1 material certificates.

Fixed Ladder Parts — Every Component, Every Spec
A fixed ladder is a small bill of materials — and each part has a real number. Know the parts and you can spec, quote, and inspect any ladder in minutes.
| Part | Standard Spec | Function |
|---|---|---|
| Side rails | Q235B / SS304 / SS316, 500 mm clear width | Carry rungs; transfer load to brackets |
| Rungs | Φ20 mm round steel, 280 mm pitch, 1.5 kN rated | Climbing surface — welded or bolted to rails |
| Standoff brackets | 8 mm plate, ≈200 mm offset | Hold ladder off the wall; give 7″+ toe clearance |
| Cage hoops | 40 × 5 mm flat steel, Φ700 mm ID | Frame of the safety cage around the climber |
| Cage vertical bars | Flat or angle bars on 300 mm centers | Close the cage; prevent fall-out between hoops |
| Rest platform | Per project, max 150 ft spacing | Rest points on long climbs |
| Swing gate / guard | Self-closing, built to opening size | Close landing openings (OSHA 1910.23(a)(2)) |
| Ladder safety device rail | Vertical PFAS rail, full climb length | Fall-arrest for new ladders >24 ft |
| Anchors / lugs | M12–M16 bolts, chemical anchors, welds | Permanent attachment to structure |
Every part is replaceable: spare rungs, hoops, brackets, and gates ship as line items, so a damaged ladder is repaired with matched parts — not rebuilt. Send us the part number or a photo and we quote within 24 hours.
Fixed Ladder Parts — FAQ
Side rails, rungs, standoff brackets, cage hoops and vertical bars, rest platforms, swing gates, anchors — plus a PFAS rail where fall protection is required.
Φ20 mm (0.79″) round steel at 280 mm (11″) pitch, rated 1.5 kN each — above the OSHA 0.75″ minimum diameter.
It fixes the ladder 200 mm off the wall (8 mm plate), keeping at least 7″ of clearance behind the rungs for a secure foothold.
Yes — replacement rungs, hoops, brackets, and gates are quoted as line items with low MOQ, so you repair in place instead of replacing the whole ladder.
40 × 5 mm hoops at Φ700 mm ID plus vertical bars on ~300 mm centers, starting 2.2 m above the base — all welded to ISO 5817 level C.
