Structural steel plates

Our standard structural steels are found in applications in steel construction, bridge building, production facilities, vehicle construction and wind towers.

Our weather-resistant structural steels are frequently used in building bridges and provide benefits such as reduced maintenance costs.

We supply

  • Special plate dimensions, including thicknesses of up to 300 mm and widths of up to 3,950 mm.
  • Our high-quality steels feature narrow analysis limits, low variation in mechanical-technological characteristics, compliance with Z tests and US tests of all classes.
  • Our steels demonstrate the best processing properties during welding, edging and cutting.
