Rectangular steel tubes combine high load-bearing capacity with a flat profile and are therefore particularly popular where space-saving and functionality are key. They offer an outstanding combination of stability, flexibility and a technical appearance – and are suitable for both load-bearing and structural design applications.
Rectangular tubes are important in many areas of metal construction because they are easy to work with and offer a wide range of fastening and joining options. They can be easily welded, drilled and combined with flange plates or connecting elements. Their design makes them particularly suitable for applications with high structural requirements or where flat profiles are needed.
Typical applications for rectangular tubes include:
- load-bearing frames and substructures
- facade, gate and fence systems
- Machinery and jig construction
- Surface-supporting elements with a defined aesthetic line
At FeNau, you’ll find rectangular tubes in various sizes and thicknesses that are ideal for professional metalwork projects – whether structurally complex or custom-designed.
