Square steel tubes are characterised by their high dimensional stability, clean lines and robust structure. They are a key component in the long products sector when it comes to load-bearing metal structures – for example, in frames, supporting structures, door and window frames, columns or railings.
The square geometry ensures that square tubes can be assembled with exceptional dimensional accuracy. The symmetrical cross-section results in uniform force distribution, which is particularly advantageous in structurally significant constructions . Furthermore, square tubes are excellent for welding, joining and combining with other components .
Typical applications include:
- load-bearing frame structures in metal construction
- railing and fencing components
- Industrial and machine frames
- structures with high dimensional accuracy requirements
At FeNau, you’ll find a selection of square tubes in various dimensions and wall thicknesses – perfect for projects that rely on stability, precise workmanship and a clear structural form.
