Application areas

Safety, reliability, cost-effectiveness and aesthetics: For structural applications, many competing requirements must be met.

Ideal for steel structures

Thermoformed structural hollow profiles are frequently used in construction and offer many advantages over other materials.

They are strong and reliable, with first-class cross-sectional properties and bending resistance. They are easy to use and feature unrestricted weldability, even in corner areas of square and rectangular sections.

With their uniform hardness distribution and low residual stress, they provide safe and reliable conditions for the manufacturing process. Glass curtain walls, for example utilizing structural hollow sections with tight corner radii and adapted to specific wall thicknesses, ensure the efficiency of the curtain wall while supporting a given load.

In addition to construction, our range of thermoformed structural hollow steel tubes are suitable for a wide range of applications including:

  • Mechanical Engineering Applications
  • agricultural equipment
  • Construction machinery
  • Naval and Offshore Structures
  • Cranes and belt conveyors
