Welded Steel Assemblies, Galvanized and Ready to Install
Laser cutting, bending, rolling and welding to your drawing, finished with hot-dip galvanizing or paint
We make welded steel assemblies from sheet, plate, tube and rectangular hollow section: cut on fiber and tube lasers, bent, rolled, welded and then hot-dip galvanized or painted. Frames, structures, racks, brackets, supports and baskets, built to your drawing and delivered ready to install.
Galvanized parts up to 12,000 mm long, 5,000 mm wide and 5,000 mm high. No minimum order weight: one prototype, a small batch or serial production.

Request a quoteFrom Flat Steel to a Finished, Galvanized Assembly
Most welded steel parts follow the same route: cut, form, weld, finish. We run that whole chain for you, so you send one drawing and receive one finished part, with no separate suppliers for cutting, welding and galvanizing to manage. We build welded steel assemblies for machine builders, solar and energy projects, storage and logistics, agriculture and construction, from one-off prototypes to serial batches.
Our Process
- Cutting. Sheet and plate are cut on Trumpf and Durma fiber lasers, heavy plate on the CNC plasma table. Round tube, square tube and rectangular hollow section are cut on a BLM 3D tube laser, including bevels for weld preparation and slots for tab-and-slot assembly.
- Bending and rolling. Brackets, channels and covers are formed on CNC press brakes. Shells, rings and curved plates are rolled from Ø300 mm up to Ø8,000 mm.
- Welding. Assemblies are fitted in jigs and welded by qualified welders, or by KUKA robots when the batch justifies it. Welding is certified to EN 1090-2 EXC2 and EXC3 and ISO 3834-2.
- Finishing. Parts are hot-dip galvanized to EN ISO 1461, sandblasted and painted, powder coated, or both galvanized and painted (duplex) for harsh outdoor use.
- Inspection and packing. Dimensions and welds are checked against the drawing, then parts are packed on pallets or in crates for truck or container shipment.
Hot-Dip Galvanizing for Large Parts
Galvanizing protects steel for decades outdoors, but it also sets limits: the part has to fit the bath and the design has to let zinc flow in and out. Our galvanizing takes parts up to 12,000 mm long, 5,000 mm wide and 5,000 mm high, enough for long frames, beams, posts and complete welded structures in one dip. Coating thickness follows EN ISO 1461 for the steel thickness, unless your specification asks for more.
Before production we check your drawing for vent and drain holes, closed hollow sections and overlapping plates, so the parts come out of the bath clean and undistorted. If a detail needs changing for galvanizing, we tell you before we cut.
Typical Parts
- Welded frames and base frames from rectangular hollow section
- Steel structures, supports and mounting frames for solar and energy projects
- Storage and transport racks, stillages and baskets
- Brackets, consoles, cable and pipe supports
- Platforms, guards and machine enclosures
- Rolled rings, shells and curved parts welded into assemblies
Simple Parts, Quoted Fast
When an assembly needs no machining, cost is driven by steel weight, cutting, welding length and finish, so we can quote it quickly and build it efficiently. Send your drawing with the quantity and the finish you need, and you will have our quotation within 2–3 working days. Machining is available too when a part needs it, on our own boring and milling machines.

Frequently Asked Questions
What is the largest part you can galvanize?
Up to 12,000 mm long, 5,000 mm wide and 5,000 mm high.
Is there a minimum order?
No minimum weight. We make prototypes, small batches and serial production.
Which materials do you use?
Sheet, plate, round tube, square and rectangular hollow section and structural profiles, mainly in S235, S275 and S355. Stainless steel on request.
Can you paint over galvanizing?
Yes. Duplex coating, galvanizing plus paint or powder coating, is available for harsh environments or a specific colour.
Do you work to EN 1090?
Yes. We are certified to EN 1090-2 for execution classes EXC2 and EXC3. See EN 1090 certified fabrication.
