Rectangular and Square Tubes

We manufacture a variety of laser welded square and rectangular hollow sections. We supply tubing mostly in stainless (304/L and 316/L) and carbon steel grades (S235, S355). That said, we can also accommodate less common materials, such as high strength steel (ex. S690, FineXcell 690, Dillmax 690, Weldox 700,…).
Profiles can be delivered in traditional lengths of 6 and 12 meters, or cut to size with a length tolerance of -0/+3 mm and a maximum bar length of 15 meters.
Please contact us or send us a drawing of the square or rectangular tube that you need, and we’d be glad to provide you with a quote!

Dimensional Ranges

  • Size ranges for square hollow sections: from 40×40 to 400×400 mm
  • Size ranges for rectangular hollow sections: from 50×30 to 400×200 mm
  • Wall thickness from 3 to 15 mm

Should your required dimensions differ from this range, please fill out the inquiry form anyways.

    What differentiares Montanstahl’s rectangular hollow sections from traditional MAG-welded tubes widely available on the market?

    Custom sizes

    We can deliver tubes with special geometries and with different wall thicknesses. We are also able to manufacture slated and bent hollow sections. We manufacture tubes from laser-welded metal strips, which means that the only limitations lie in the raw material availability of the desired wall thicknesses.

    Sharp-corners and edges

    Our tubes have the distinctive feature of having sharp-corners, which is highly appreciated by architects as it allows for elegant and modern constructions. Minimal radii is also often preferred for functional purposes in structural and mechanical applications.

    Tighter tolerances and better surface

    Thanks to the significantly lower distortion during welding, laser-welded profiles can achieve much tighter tolerances on the overall geometry, torsion and straightness compared to conventionally welded profiles.

    Standard Rectangular Steel Tubes in Carbon Steel

    Thanks to the significantly lower distortion during welding, laser-welded profiles can achieve much tighter tolerances on the overall geometry, torsion and straightness compared to conventionally welded profiles.

    SR-Profiles are a more cost-efficient alternative to laser welded hollow sections. We hold on stock and supply the following SR tubes:

    • Mild steel (S235)
    • 60mm width
    • 6mm wall thickness
    • Bar length of 8m or 10m
