What our machines actually do
Every figure on this page is a measured capability from our shop floor in Hung Yen, Vietnam — not a catalogue claim. Where a machine has a limit, we state the limit. You should be able to decide from this page alone whether your drawing fits.

| Press force | 110 tonnes |
| Maximum thickness | 4 mm across the full 3,000 mm |
| Angular tolerance | ±2° |

Plate rolling
1 machine · 3-roll
| Roll diameter | Ø190 mm |
| Roll length | 1,800 mm |
| Minimum rolled diameter | Ø250 mm |
| Maximum thickness | under 6 mm |
| Roundness / taper after rolling | under 2 mm |
Welding
TIG · MIG · MMA
| Quality requirements | ISO 3834 (-2, -3, -4) |
| Weld inspection | VT visual · UT ultrasonic · MT magnetic particle |
| Weld quality level | ISO 5817 (level B, C or D as required) |
| Welded structure tolerance | ISO 13920 |
| Welder qualification | ISO 9606-1 (steel and stainless) |
| Material traceability | MTC per heat lot |
For stainless steel we treat pickling and passivation after welding as part of the process, not as an extra on request. The heat-affected zone loses its passive layer; if it is not restored, the weld is exactly where corrosion starts.
Surface treatment
In house
| Blasting | Shot blasting to Sa 2.5 |
| Painting | Enclosed-booth painting · powder coating |
| Galvanising | Hot-dip galvanising |
Having all four stages — cutting, forming, welding, finishing — inside one factory means you coordinate one supplier, and no tolerance stack-up appears from joining parts made in different places.
Supporting machines
On site · detailed specifications being compiled
- Wire EDMHardened materials and complex profiles a milling cutter cannot reach
- OKK milling machineMilling, drilling, tapping and chamfering where surface finish and tight tolerance matter
- Laser weldingThin parts prone to distortion, and welds with a cosmetic requirement
We would rather list these without numbers than publish numbers we have not verified. Ask us and we will confirm the specification for your part.
What we work in
| Carbon steel | SS400, SCM440 and equivalents |
| Stainless steel | 304, 316 / 316L |
| Aluminium | Sheet and profile |
| Copper alloys | Brass (laser cut) · pure copper (machined or stamped) |
| Traceability | Mill test certificate (MTC) per heat lot, for every project |
The standards we work to
| Standard | Scope |
|---|---|
| ISO 9001:2015 | Quality management system — certified |
| ISO 3834 (-2, -3, -4) | Quality requirements for fusion welding |
| ISO 5817 | Quality levels for fusion-welded joints |
| ISO 13920 | General tolerances for welded constructions |
| ISO 9606-1 / -2 | Welder qualification — steel and stainless / aluminium |
| ISO 286-1 | Tolerance and fit system, IT grades |
| ISO 2768-1 | General tolerances, linear and angular |
| ISO 9013 | Thermal cutting — dimensional tolerance and cut quality |
| EN 1570-1 | Safety requirements for lifting tables |
We have been manufacturing to ISO, DIN and ASME drawings since 2006. European customers do not accept a part — they accept a part with its file. A missing weld inspection report or a missing MTC stops the delivery no matter how good the machining is, so that file is our default process, not an extra.
What we do not do
A supplier whose every page says yes is a supplier you cannot plan around. These are our limits, stated before you send a drawing.
- Pure copper is not laser cutMachined, milled or stamped instead, depending on geometry
- Laser cutting stops at 20 mmCarbon steel above 20 mm goes to the plasma head (25 mm) or the oxy-fuel head (200 mm, steel only); stainless and aluminium above 15 mm we do not cut in house
- Plate bending stops at 4 mmThicker plate becomes a welded construction, or one outsourced operation
- Rolling stops at 6 mm thickness and 1,800 mm roll lengthLonger or thicker shells need a partner operation for the rolling step
- No classification society approvalWe hold no DNV, ABS or Lloyd’s Register approval. We manufacture marine components to customer drawings and specification; the certification scope must be agreed up front
- PED 2014/68/EU scope to be agreedFor pressure equipment entering the EU, the documentation scope is discussed before quoting, not after

Audits and factory visits are welcome. The whole manufacturing capability listed on this page sits on one site, so one visit covers all of it.
Send a drawing
We return a quotation within 24 working hours. We accept PDF, DWG, DXF, STEP and IGES.
Your drawings are used to prepare the quotation only. They are not shared with any third party, and we are ready to sign an NDA before you send anything.
