Where Your Cat Ladder Is Actually Built

Trade houses quote you a factory's products. We are the factory. Every cat ladder on RoofCatLadder.com is cut, bent, welded and shipped from our own workshop in Jingxing Mining District, Shijiazhuang — so your quote comes from the production floor, not a middleman. Non-compliant access can void insurance cover and trigger regulator citations after any incident.

Integrated Workshop

Cutting, bending, welding and trial assembly under one roof — one quality system, one schedule, one accountable name.

Full Material Matrix

Q235B hot-dip galvanized steel as standard, plus SS304 / SS316 stainless (mill-certified), aluminium and GRP / FRP — all fabricated in-house.

Hot-Dip Galvanizing (ISO 1461)

85–100 µm coating thickness verified on every batch — one-piece runs to 14 m, bolted runs to 25 m.

Equipment & Capability

Cutting, Bending, Welding & HDG to ISO 1461

The machinery to hold tolerances on repeat runs — from a single 2 m roof ladder to a 25 m bolted system — with hot-dip galvanizing to ISO 1461 under our QC.

CNC Plasma / Flame Cutting

Rung and stringer blanks cut from Q235B, SS304 and SS316 plate with repeatable accuracy.

160T Hydraulic Bending

Cold-formed rungs, hoop sections and stiles with consistent angles across an entire run.

MIG / MAG Welding Stations

Cat ladders and cages welded at dedicated MIG/MAG stations with 100% visual inspection against the approved drawing.

Hot-Dip Galvanizing to ISO 1461

Full-immersion HDG to ISO 1461 at 85–100 µm — the coating is measured on every batch.

Production Line — Five Stations, One Building

A cat ladder moves through five fixed stations inside the plant. Each one has a named standard and a paper trail — so an auditor can reconstruct any order, years later, from the QC file alone.

Station	What Happens	Standard / Evidence
1. Incoming material	Steel and plate checked against the order before it enters stock	EN 10204 3.1 mill certificate on file
2. Cutting & forming	CNC plasma and flame cutting; 160T press brakes form stiles, rungs and cage hoops	Dimensional check against the approved drawing
3. Welding & assembly	Cat ladders and cages welded at dedicated MIG / MAG stations	100% visual inspection against the approved drawing
4. Hot-dip galvanizing (ISO 1461, QC-verified)	Full-immersion HDG; coating thickness verified per batch	ISO 1461 — typical 85–100 µm
5. Trial assembly & photo	Every ladder dry-assembled, then export packing and loading photographed	QC file + loading photos, kept on file

Monthly Export Capacity

8–12 Containers of Cat Ladders a Month

Production runs 15–25 working days from drawing approval. A single order or a container volume run down the same lines — your batch never queues behind a bigger customer indefinitely.

25 m single-run builds
One-piece runs to 14 m, bolted runs to 25 m; taller systems get rest platforms per OSHA 1910.28 & EN ISO 14122-4

Factory FAQ

What equipment does the plant run?

CNC plasma and flame cutting, 160-ton hydraulic bending and MIG/MAG welding stations serve a focused cat ladder workshop in Jingxing Mining District, Shijiazhuang — fabrication, welding and trial assembly are in-house; hot-dip galvanizing to ISO 1461 with coating verification on every batch.

Can you build a 25-meter custom cat ladder in one run?

One-piece runs reach 14 m (the galvanizing bath limit); bolted single runs reach 25 m (our fabrication limit); taller systems use multi-runs with rest platforms, fall protection per OSHA 1910.28 & EN ISO 14122-4 — all standard work for our factory.

How long does production take after we approve the drawings?

Fifteen to twenty-five working days from drawing approval to finished, inspected goods. Container booking and export documents then follow your chosen Incoterm, and the compliance file ships with the order.

How do you control hot-dip galvanizing thickness?

Every batch is checked against ISO 1461, with typical coatings of 85–100 µm. Coating results go into the order QC file, and records are retained on file.

Which steel and material grades can we specify?

Q235B hot-dip galvanized steel as standard, with SS304 and SS316 stainless (mill-certified), aluminium and GRP/FRP also fabricated in-house — one factory covering the full cat ladder material matrix.

Does the factory take small orders alongside container runs?

Yes — trial orders start from 1 unit. The same five-station line builds a single 2 m roof ladder or a 25 m bolted system, and a one-off order runs down the same lines as container volume, so it never queues indefinitely behind a bigger customer.

Can the plant keep up with repeat container volumes?

The workshop ships 8–12 containers of cat ladders a month, with production at 15–25 working days from drawing approval. Repeat container programs are scheduled across the five fixed stations, and mixed loads of HDG and stainless builds are quoted per load plan.

Can we audit the factory before ordering?

Yes — audit visits are welcome at the Jingxing Mining District works in Shijiazhuang. Each of the five production stations has a named standard and a paper trail, so an auditor can reconstruct any order from the QC file alone, years later.

Can we order spare parts for ladders already installed?

Yes — spare rungs, brackets and gates are available as parts, which keeps a fleet of installed Dengtai climbs serviceable without full replacements. Quote the item with the original order reference and we confirm availability and pricing within 24 hours.
