We have three prefabrication plants for steel structures, with a combined production capacity of 18,000 tonnes of structures per year. All plants have been awarded the Factory Production Control certificate issued based on the requirements of the PN-EN 1090-1:2009+A1:2011 standard.

We are specialists in manufacturing, repairing, modernising and assembling various steel structures, ranging from class EXC1 to the most demanding class EXC4, as per the PN-EN 1090-2 standard. The wide range of technologies we use allows us to manufacture structural components from such steel types as 16CrMo (heat-resistant chromium-molybdenum), 16Mo3 (boiler steel with increased molybdenum content), S355J2W (Corten). What sets us apart from our competitors in the Central European region is our in-house large-scale machining, metal spraying and SD stud welding.

Our business includes the manufacture of steel structures:

  •  infrastructure – road and railway bridges, viaducts, footbridges,
  • for general and industrial construction,
  • for the energy industry,
  • for metallurgy,
  • for the mining industry,
  • cylindrical tanks,
  • machine and equipment bodies,
  • environmental protection equipment,
  • dust collection pipes and ducts.

The factories in Krakow and Kleszczów provide a capacity of approximately 1,200 tonnes per month and the ability to produce components of up to 40 tonnes and maximum dimensions of 5m x 30m x 5m.  The “Konstalex” factory specialises in the manufacture of heavy steel structures, with a maximum element weight of up to 70 tonnes and overall dimensions of 5m x35m x 5m. Depending on the type of steel structure, the plant produces approx. 600 ÷ 1,000 tonnes of structures per month.
