Six processes, one roof, one invoice.
Cutting, punching, bending, welding, finishing and assembly happen in the same building. That is what makes a real lead time possible instead of a guess — fastest 15 working days from approved drawing and deposit, transit excluded.
The machines behind the promise.
Replace model names and quantities with your own before publishing. Buyers read this table closely.

What we can hold, and what we cannot.
Honest limits save both of us a rework cycle. If your tolerance is tighter than this table, tell us early.
| Feature | Standard (default, no extra cost) | On request | Notes |
|---|---|---|---|
| Laser-cut profile | ±0.20 mm | ±0.15 mm | Parts up to 1000 mm |
| Laser-cut profile | ±0.30 mm | — | 1000 – 2000 mm |
| Laser-cut profile | ±0.50 mm | — | Over 2000 mm |
| Hole diameter (Ø ≥ 3 mm and ≥ sheet thickness) | ±0.15 mm | — | Smaller holes drift at the pierce point |
| Hole position, in-plane | ±0.20 mm | ±0.15 mm | Measured hole to hole |
| Bend angle | ±1.0° | ±0.5° | First article checked, then every 25th |
| Flange length, ≤ 500 mm | ±0.30 mm | ±0.20 mm | Bend to edge |
| Flange length, > 500 mm | ±0.50 mm | ±0.30 mm | Bend to edge |
| Hole-to-bend distance | ±0.30 mm | — | Keep holes ≥ 2.5 × thickness from the bend line |
| Overall size after forming, ≤ 1000 mm | ±0.50 mm | — | Across all bends |
| Overall size after forming, > 1000 mm | ±1.00 mm | — | Across all bends |
| Cut-edge burr | ≤ 0.10 mm | Deburred or polished edge | Material up to 6 mm |
| Flatness | Not controlled | Stress relief + leveling | Reference value 0.8 mm per 1000 mm |
This table applies to general sheet metal fabrication. It is not equivalent to ISO 2768 or precision machining tolerances unless agreed in writing. Drawings that call ISO 2768-m or tighter, GD&T, or any value tighter than the rows above are reviewed before we quote — and if we cannot hold it, we say so instead of quoting it.
Metric to inch: ±0.10 = ±0.004″ · ±0.15 = ±0.006″ · ±0.20 = ±0.008″ · ±0.30 = ±0.012″ · ±0.50 = ±0.020″ · ±1.00 = ±0.040″
Powder coat, plating and marking.
We pretreat, cure at 180 °C and check adhesion and thickness on every batch. If a finish is wrong for the environment, we will say so before you order it.
What ships with every batch.
Paperwork
Mill certificate, dimensional report, FAI package on new parts, packing list with batch number.
Traceability
Batch number on the carton and the inspection sheet. If something is wrong, we can find the run.
Correction
We rework or remake at our cost when the part does not match the approved drawing or sample.
Packed for a container, not for a shelf.
Export cartons, foam or honeycomb separation, reinforced pallets and clear labels. You get packing photos before the carton is sealed — the same photos we keep on file.
- ✓Flat-pack optionBent and coated but unassembled — roughly half the container space.
- ✓Drop testCarton drop test on request, with a photo record.
- ✓TermsFOB Shenzhen / Yantian standard. CIF and DDP quoted on request.
Not sure if your part is a fit?
Send the drawing and we will tell you honestly — including when the answer is no.
