Custom Made Cage Ladder – Built to Your Spec
Non-standard sizes, unusual heights, special materials — a custom made cage ladder starts with your drawing and ends with a unit built to match it exactly.
- Built to Your Drawing
PDF, DWG or a written spec — we fabricate to match
- Any Height & Configuration
Single-run to 25 m; multi-run with rest platforms beyond
- Material of Your Choice
Hot-dip galvanized Q235B, SS304 or SS316, PMI-tested
How Custom Works
Free CAD Drawings & Production Schedule
A transparent, four-step process — send your drawings, get a 24h quote, approve the schedule, and we ship.
1. Send Drawings
Share your PDF or DWG, or describe the height and specification.
2. 24h Quote
Itemized quote with free CAD drawings and a drawing review.
3. Production Schedule
Clear milestones after drawings are approved — typically 15–25 working days.
4. Ship
Fabricated, inspected and shipped with the full compliance file.
The Honest Question First
When Custom Earns Its Premium — and When It Doesn't
Custom costs 10–20% over standard geometry because it buys engineering hours, not mystique. Before you pay it, check which side of this table you're on.
Order custom when…
- climb height falls between catalog sizes
- exit is walk-through, side-step or roof-hatch
- governing standard fixes hoop/clearance geometry (AS 1657, BS 4211)
- anchor base is a tank shell, silo curve or steel frame
- material must match a corrosive zone (SS316, FRP)
Buy standard when…
- dimensions match a standard build (2–20 m steps)
- step-across exit on a flat wall works
- HDG Q235B suits the environment
- schedule beats spec — stock units dispatch now
Standard geometry saves 10–20% with identical compliance docs — see pricing.

Compliance Without Compromise
Fully Welded & OSHA 1910.28 Compliant
Custom does not mean off-spec. Every custom built cage ladder is fully welded, engineered to the standard and ships with its compliance file.
- DoC – OSHA 1910.28 & EN ISO 14122-4
Declaration of Conformity to the relevant standard
- MTC 3.1 Material Certificate
EN 10204 3.1 for Q235B / HDG / SS304

The Honest Economics of Changing Your Mind
Change Cost Table: What a Drawing Change Costs at Each Stage
Custom projects change — sites get re-surveyed, platforms move, standards get named late. The cost of a change depends entirely on when you make it. Here is the real ladder, mapped to the actual nodes of our process.
| Stage of Your Order | What You Can Still Change | Cost to You |
|---|---|---|
| CAD / concept (before approval) | height, width, cage size, exits, material, standard — everything is lines on paper | Free — unlimited revisions on the CAD drawing, with the 1–3 day engineer review |
| Quote stage | quantity, finish tiers (HDG / SS304 / SS316), freight terms, packaging | Free — requote in 24 hours, pricing line by line |
| Production drawing released, before cutting | dimensions, rung count, hoop spacing, platform positions | Free — nothing is ordered to stock; cutting starts only after your release |
| Cutting and jig welding | items not yet cut: cage hoops, gates, accessories | Difference — we re-cut affected parts at material cost difference, no penalty fee |
| After welding, before galvanizing | add-on weldments only (brackets, tabs); geometry is fixed | Difference plus a bench hour — cheapest structural change window left |
| After HDG coating | no structural change — rework means stripping and re-galvanizing | Full rework of affected parts — we will tell you honestly if a new unit is cheaper |
| In the container | labeling and documents only | Free — packing list and DoC updated to the as-built configuration |
The pattern is simple: on paper and before cutting, changes are free by design. Lock your survey numbers before drawing release and the whole table stays on the free side.
Getting the Ladder You Actually Need
Custom Build, Standard Catalog, or Modifying Stock: The Decision Guide
Three ways to get a ladder onto your structure — factory custom, standard catalog, or buying stock and modifying it locally. One of them quietly voids the compliance file. The table and checklists make the right route obvious.
| Criterion | Factory Custom (Dengtai) | Standard Catalog | Modified Stock |
|---|---|---|---|
| Fit to structure | exact — built to your survey, 100 mm steps | nearest catalog size, shimmed on site | approximation after cutting |
| Compliance file | DoC, MTC, calcs match the as-built geometry | matches catalog geometry | voided — nobody certifies a cut-and-rewelded ladder |
| Price | standard + 10–20% engineering line | baseline $95/m HDG | cheap unit, expensive liability |
| Corrosion protection | HDG after final welding, ISO 1461 intact | same | cut edges burn zinc — field repair never matches 85–100 μm |
| Lead time | 1–3 day review + 15–25 days build | 15–25 days | days — until the inspection finds it |
Red flags — you are buying risk
- "Just cut it on site" — modifies protected geometry and voids the DoC
- Custom priced as a multiplier — "double for custom" hides the real engineering line
- No revision window before cutting — free changes on paper are the cheapest insurance in the project
- Approval drawing skipped — no signed drawing means no reference for what "correct" is
Green lights — proceed with confidence
- Free CAD before commitment — you see the exact build before paying
- Changes free before cutting — the schedule protects your survey corrections
- DoC cites your named standard — geometry engineered to OSHA 1910.28 / EN ISO 14122-4 up front
- Trial assembly included — bolt-together proven before it ships

Custom Build Value at a Glance
What a Custom Cage Ladder Buys Your Site
Five features of the custom route, and the outcome each lands on your project.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Free CAD before commitment | exact geometry reviewed by engineers, 1–3 days | you approve what will be built, not a catalog approximation |
| Changes free before cutting | survey corrections cost nothing on paper | re-surveyed heights never become a rework invoice |
| 100 mm height steps, 2–25 m | any climb, bolt-together above 14 m single piece | the ladder lands where the platform actually is |
| As-built compliance file | DoC, MTC and calcs match your geometry | inspection passes on documents, not on hope |
| Custom premium only 10–20% | engineering time, not a price multiplier | exact fit without doubling the budget |
