About our company
ALT a.s.
Our company focuses primarily on mechanical engineering and our products are intended mainly for export. The company flexibly reacts, within the limits of its manufacturing capacity, to every demand on the mechanical engineering market.
Modern CNC machines
State-of-the-art machining centres – machining of welded products with lengths up to 8 000 mm, using horizontal CNC boring machines.
Modern material cutting
The material-cutting technology has been subject to significant modernization thanks to the purchase of new machines from the Microstep company.
Transport within the Eurozone – We arrange transport of products within the entire European Union.
Quality control
Quality control and checks of product dimensions and geometrical features are more than a standard for us and that is why we use the state-of-the-art measuring technologies for that purpose.

Within our current manufacturing processes, we use a robotic welding centre to weld steel frame assemblies and so-called tower subsets that are later used to manufacture frames. Two burners are used within welding processes – a standard burner (single) and double burner (tandem). Welding of assemblies is faster thanks to the features of the technological equipment. Weld quality and top finish are guaranteed.

Our employees are highly qualified and skilled and in addition, we offer also favourable prices. We draw on our long-term experience in the area of manufacture of ships and earth-moving and building machines. We have been supplying products to and cooperating as a subcontractor with leading foreign companies in Germany and Austria.
