Steel Grades
Steel Cage Ladder Options - Q235B & Q345B
Q235B standard or Q345B heavy-duty - steel grade by load. Fully welded, factory made, with MTC and DoC on every order.
- Q235B - Standard (≈A36)
Best-value structural steel for general industrial access
- Q345B - Heavy Duty (≈A572 Gr.50)
Higher strength for tall structures, heavy loads and wind-loaded sites
- Fully Welded Construction
Continuous welded cage hoops and straps, made to order
| Grade | Equivalent | Best For |
|---|---|---|
| Q235B | ≈ A36 | Standard industrial access |
| Q345B | ≈ A572 Gr. 50 | Heavy-duty, tall, wind-loaded |
| Finish | HDG ISO 1461 | 85–100 μm galvanizing |

Field Story — a Cement Plant That Quoted Catalog Prices First
The 7 m Gantry Climb That Cost a Third of the Catalog Number — Same Steel, Same Standard
Steel is where factory-direct pricing shows its widest gap. This is a buyer who priced the same geometry two ways and bought the one with the better paper trail.
A cement plant's conveyor gantry needed a 7 m caged ladder replaced during the winter shutdown. The buyer's first quotes came from US industrial catalog channels, where complete caged ladders ranged $1,325 to $7,400 in August 2026 pricing — for climbs no taller than this one. The specification was nothing exotic: steel stringers, rungs Φ20 at 280 mm, cage from 2.2 m, HDG finish.
Our quote returned in 24 hours: the same 7 m HDG steel caged ladder at the $95/m factory rate — about $665 for the climb itself — with hoops 40×5 at 1500 mm, straps 30×3, and the full compliance file included rather than priced as an extra. Even adding sea freight at the typical $280–550 band, the landed comparison was not close, and the catalog units did not include MTC 3.1 or a DoC naming EN ISO 14122-4 and OSHA 1910.28.
Production ran inside the 15–25 day window, the unit trial-assembled at the factory so the gantry bracket pattern matched first time, and the shutdown crew bolted it in half a shift. The plant kept the trial-assembly photos and material certificates on file — and the buyer kept our quote sheet as the reference price for every climb on the next budget round.
| Quote Line | Catalog Channel | Dengtai Factory-Direct |
|---|---|---|
| 7 m HDG caged ladder | within $1,325–7,400 range, Aug 2026 | ≈ $665 at the $95/m factory rate |
| MTC 3.1 material certificate | extra, when available | included with the order |
| DoC — OSHA 1910.28 / EN ISO 14122-4 | rarely offered | issued with every unit |
| Trial assembly before dispatch | not standard | bench-proven bolt pattern, photographed |

Steel, or the Metal Next to It
HDG Steel Cage Ladder Against Stainless and Aluminium — Deciding by Air, Not by Brochure
The metal decision takes one honest look at what your air does all day. Four situations cover almost every steel-ladder enquiry that reaches our engineering desk.
| Choose | When the Air Around Your Ladder |
|---|---|
| HDG steel at $95/m | is ordinary industrial or outdoor air — dust, rain, humidity — where 85–100 μm of kettle zinc per ISO 1461 holds for decades at the lowest cost per meter |
| SS304 at 1.8× | carries chemical splash or regular washdown chemistry — plating lines, food caustics — where zinc coating is the first casualty |
| SS316 at 2.5× | is salt-heavy — marine, coastal, desalination — where chloride mist pits lesser metals and the 2.5× premium buys decades, not years |
| Aluminium 6063-T5 | belongs to hygiene zones and no-crane installs — no coating system at all and roughly 40% less mass to carry on the day |
Steel-ordering mistakes that surface at inspection
- Accepting “galvanized” without the standard — spray zinc and paint both answer to the word; only ISO 1461 hot-dip at 85–100 μm belongs in your spec
- Buying steel with no material certificate — an MTC 3.1 is your proof of Q235B chemistry; without it the asset is uninsurable in an audit
- Skipping weld records — our welds are certified to ISO 5817 level C; specify the same of any vendor or the cage hoop joints are opinions
- Paying catalog markup for standard geometry — a Φ20 rung, 280 mm spacing climb is our standard build, not a custom engineering project
Steel Specs, Spelled Out
Five Things the Steel in Your Cage Ladder Does for the Next Decade
Each row is a line you can verify on delivery day — and the ten-year result it purchases for the asset owner.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Q235B steel with MTC 3.1 | heat-traceable chemistry on file | insurance and audit questions answered from a drawer |
| Welds to ISO 5817 level C | cage hoop joints certified, not decorative | the cage performs the day someone leans on it hard |
| HDG 85–100 μm per ISO 1461 | kettle-dipped zinc inside and out | no repaint budget line for the first decade |
| 1.5 kN rungs at Φ20 × 280 mm | tool and body loads without flex | climbers trust the ladder with a full parts bag |
| Single-piece builds to 14 m | fewer splices per climb | fewer bolted joints on the annual inspection list |
