Metalworking Processes

Our metalworking capabilities include a wide range of precision forming and joining techniques.

These include:

  • Stamping – High-speed and accurate shaping of metal components using custom-made dies and presses, ideal for large-volume production.
  • Bending – Controlled deformation of metal sheets to achieve specific angles and shapes, with consistent results even in complex geometries.
  • Straightening – Precision adjustment and correction of metal parts to ensure flatness, dimensional accuracy, and optimal assembly conditions.
  • Riveting – Reliable and durable mechanical joining of components, commonly used in applications requiring strength without welding.

 

These processes are essential in delivering high-quality parts for various industries, ensuring strength, functionality, and exact adherence to customer specifications.

Welding

We use a wide range of welding methods to meet the most demanding requirements of our customers. We hold the ISO EN 3834-2 certificate (welded steel structures) and specialize in welding lightweight steel structures. We have experience and trained personnel in welding projects for the NPP program (Nuclear Power Plants).

Metal Surface Treatments

We offer a comprehensive portfolio of high-quality metal surface treatments — ensuring durability, protection, and a premium finish.

Our technologies include:

  • Chemical degreasing – using advanced Fibrimatic equipment and perchloroethylene.
  • Powder coating – semi-automatic line with C5M corrosion resistance (up to 5000 hours, ISO 12944).
  • Phosphating – chemical passivation for enhanced coating adhesion.
  • Zinc plating – zinc and zinc-chromium coating with high-gloss passivation (blue/yellow).
  • Wet coating – top-tier Wagner technology with C5M corrosion resistance (up to 5000 hours).


Maximum part sizes:

  • Powder coating: 1400 × 2600 × 500 mm
  • Zinc plating: 2400 × 1000 mm
