Production Line
Five Stations, One Building, Zero Handoffs to Strangers
A cage 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 stringers, rungs and hoops | Dimensional check against the approved drawing |
| 3. Welding & assembly | Cages and stringers welded at 14 dedicated stations | ISO 5817 Level C acceptance criteria |
| 4. Hot-dip galvanizing | 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 10 years |

You Do Not Need a Flight to Audit Us
What a Real Factory Can Produce in 48 Hours — and a Fake One Cannot
Most buyers never visit the plant. The audit still happens — it happens over email. Four things to request that cost a genuine factory nothing to provide.
Ask for these — free, fast, verifiable
- A live video walkthrough — cutting, bending, welding and assembly in one continuous shot, scheduled within days
- Dated station photos — the same five stations, timestamped, with work in progress
- A recent MTC 3.1 sample — EN 10204 certificate with heat numbers you can have verified
- Container loading photos — from this month's shipments, 8–12 × 40' boxes leave monthly, so there are always fresh ones
Answers that end the audit
- Only renders and brochures — no photographs of actual production
- A "factory tour" of an office — trading companies show meeting rooms, not welders
- Refusal to name the galvanizer — HDG is where corner-cutting hides; ISO 1461 at 85–100 μm needs a real kettle

Capacity You Can Walk Through
What Buying From the Plant Floor Gets You
Five structural advantages that exist only when the seller and the welder share a roof.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Five stations under one roof | CNC cutting, bending, welding, HDG finishing, trial assembly | one quality system, one schedule, one accountable name |
| 3,000 m², ~1,500 t/year | single ladder or multi-container batch on the same lines | your order never queues behind a bigger customer indefinitely |
| 8–12 × 40' containers monthly | export packing, bracing and loading plans are weekly routine | goods arrive as documented as they left |
| Factory visits welcome | walk the stations, review the compliance file in person | underwrite the supplier with your own eyes, not their adjectives |
| Direct engineer access | the person who cuts steel answers your technical email | answers in hours that resellers forward for days |
