Laser Cutting, Plasma Cutting, Bending and Rolling
Cut and formed parts are the start of most fabrications, and we also supply them as finished kits. Work comes from DXF, STEP or the drawing, nested for material yield and prepared for welding or machining.
Fiber and Tube Laser Cutting
Clean edges and tight tolerances on sheet, plate and profiles.
- Trumpf TruLaser and Durma fiber lasers
- Mild steel, stainless steel and aluminium
- BLM tube laser with 3D and bevel heads
Plasma Cutting of Heavy Plate
Thick plate for frames, flanges and structural parts, plus beam processing.
- CNC plasma cutting of plate up to 180 mm

- 4–120 mm thickness; limits drop for wear plate
Sandblasting, Painting, Galvanizing and Coating
Parts leave blasted and coated to the system on your drawing, ready to assemble. We sandblast, paint, powder coat and galvanize, then take the parts through inspection and packing.
Sandblasting and Painting
Surface preparation and coating for frames, machined parts and large structures.
- Sandblasting and mechanical surface preparation
- Grinding and finishing of welds and edges
- Industrial wet paint and powder coating to your specification
Galvanizing and Protective Coatings
Hot-dip and electro galvanizing for outdoor and structural parts.
- Hot-dip galvanizing and zinc coating to EN ISO 1461
- Parts prepared and fabricated for galvanizing
- Inspected and packed on return
Export Packaging and International Transport from İzmir
A good part can still arrive damaged. We pack each order for its size, weight and route: crates and stillages for machined components, pallets and protective film for painted fabrications, and reinforced frames for heavy or oversized pieces. Machined faces and bores are protected inside the crate.
We coordinate loading and transport from İzmir to your plant, by road within Europe or by container shipment. Incoterms and the destination plant are set on the quotation, so the landed cost is clear before production starts.
Engineering and Manufacturing Consulting
We manufacture to your file, and we read that file the way the people who will build it do. Before any plate is cut we review weld access, machining stock, tolerances and material. If a small change would make the part cheaper, faster or more repeatable to build, we say so on the quotation, and you decide.
This is manufacturing engineering, not a machine-design office. It covers drawing review, material and process selection, fabrication planning and fixture thinking for serial parts. If you only have a concept or a 3D model, we can help turn it into a drawing set that is ready to quote and build.
Inspection, Traceability and Certificates
Parts are checked against the drawing at the stage where a problem is cheapest to fix: dimensions before packing, weld checks after assembly, and material verified against heat numbers from receipt to shipment. Shafts, housings, flanges and welded assemblies are measured by CMM, with height gauges and standard measuring equipment.
When the specification asks for it, we supply EN 10204 3.1 material certificates and coordinate non-destructive testing (UT, MT, PT or RT), including third-party attendance on request. Read more on our quality and inspection page.

Yes. Heavy project fabrication is built one-off or in small numbers. Repeat parts are built in fixtures from a frozen drawing, and can run as call-off orders over time.
Can you weld a frame and machine it after welding?
Yes. We plan machining stock at fit-up so faces, bores and hole patterns can be finished after the weld has cooled.
What is the largest part you can machine?
Vertical turning reaches Ø4,200 mm in diameter and 2,500 mm in height. Boring and milling travel reaches 4,500 × 2,500 × 2,000 mm, and long-bed turning reaches 6,000 mm in length. If your part sits near an edge, send the drawing and we will confirm the machine.
How thick can you cut plate?
CNC plasma cutting handles plate up to 180 mm. Fiber laser cutting covers sheet and thinner plate in mild steel, stainless steel and aluminium, and the tube laser cuts round, square and rectangular profiles with bevel heads.
Do you paint and galvanize the parts?
Yes. We sandblast, paint, powder coat and hot-dip galvanize to your specification, then the parts go through inspection and packing.
Which certificates and documents can you supply?
EN 10204 3.1 material certificates with heat-number traceability, dimensional inspection reports, and CE marking under our EN 1090 EXC3 certification where the product requires it. NDT such as UT, MT, PT or RT is coordinated when the specification requires it.

Contract Manufacturing in Türkiye for European OEMs: Steel Fabrication, CNC Machining and Finishing
Nika Steelworks is a contract manufacturer in İzmir, Türkiye. Since 1972 we have built welded steel fabrications and CNC machined components to customer drawings for machinery builders, engineering companies and industrial buyers across Europe. This page describes the services behind that work, so buyers and engineers can see early what we can make and how an order runs.
Why European OEMs outsource steel fabrication to Türkiye
For many European machinery builders, sourcing welded and machined parts from Türkiye is now a standard part of the supply chain rather than a backup. Freight times to the EU are short compared with Asian sourcing, and labour and overhead costs remain below Western European levels. Delivery on DAP or DDP terms keeps customs and landed cost simple. What decides the choice in practice is documentation, communication and consistency, and these are what we build the service around. Our guide to sourcing steel fabrication from Türkiye covers costs, customs and CBAM.
Steel welding and fabrication: heavy projects and series
Our welding and steel fabrication covers machine frames, bases, containers, enclosures and heavy weldments, as well as repeat parts built in fixtures. Welding is MIG/MAG and TIG in carbon, structural and stainless steel, certified to EN 1090-2 EXC3 and ISO 3834-2. For repeat work, see serial production of welded and machined components, or browse finished examples such as custom welded steel containers and trenchless steel jacking pipes.
Welded and galvanized assemblies, no machining needed
Many parts need only cutting, bending, rolling, welding and a finish. For these we offer welded steel assemblies, hot-dip galvanized up to 12,000 mm long, including galvanized steel structures and frames and steel stillages and galvanized baskets. Structural work is CE marked under EN 1090 EXC2 and EXC3.
Large-part CNC machining in Türkiye
Few suppliers can machine a three-metre flange or a welded machine base. Smaller CNC machining runs on Taksan milling machines with Fanuc or Siemens controls. The machine park lists every machine with its specification, and the large rotary mandrel project shows what our heavy machining can do.
Laser cutting, plasma cutting, bending and rolling
Fiber laser, tube laser and plasma cutting prepare plate, tube and structural sections for welding and machining. Laser and plasma cutting covers sheet and plate in mild steel, stainless steel and aluminium, with plasma cutting up to 180 mm. Cut parts are formed on a CNC press brake or rolled into cylinders and cones, as described on our bending and rolling page.
Surface treatment, galvanizing and coating
Finished fabrications are sandblasted and prepared for coating, as set out under sandblasting and paint. Industrial painting, hot-dip galvanizing and zinc coating are done to your coating specification, and we manage the parts through to inspection and packing. See galvanizing and protective coatings for the options.
Inspection, packaging and delivery
Parts are checked against the drawing before packing: dimensions, weld quality, and machined faces, bores and hole patterns after welding. EN 10204 3.1 certificates and heat-number traceability can be supplied, and NDT is coordinated when the specification asks for it. See quality and inspection. Orders are packed in crates, pallets or stillages for road freight within Europe or container shipment from İzmir, on EXW, FOB, DAP or DDP terms.
