Welding

When it comes to precise work, performed neatly and accurately, you need someone who knows what they're doing.

In other words, a reliable professional. From robot welding to assembly and riveting, and all the way to manual welding: our 70 qualified metal workers and welders guarantee consistent quality in everything that they do. They can even handle heavyweights, e.g. modules up to 50 tons a piece. No problem.
