Sigma beams

SIGMA BEAMS

The Weland Sigma beam is a support beam with low weight and high strength. A suitable application, for example, is for mezzanine structures.


The Weland Sigma beam is a profile with low weight and high strength. The Sigma beam is very well suited to e.g. mezzanine constructions.

Sigma beams

The Sigma beams are manufactured with a yield stress of 350 N/mm2, with hot dip galvanised finish, in a number of different standard heights, material thicknesses and lengths, and they can be used both indoors and outdoors without any further surface treatment.

The beams have punched holes with a separation of 50 mm, which match our assembly fittings and railing systems. This means that assembly can be performed quickly and easily, with no need for welding. The Sigma beams are so light that they usually do not require lifting assistance. There are also large holes in the centre of the beam for routing electrical cables and pipes.

Fittings

We stock a number of different fittings for the easy and stable assembly of Sigma beams into the desired structures. Everything is based on screwing them together using existing holes in the Sigma beams and fittings.

Fittings

Used for right-angled corners and other right-angle joins of Sigma beams at the same height. Corner joints for all Sigma beam heights are kept in stock.

Surface treatment

Our Sigma beam is hot dip galvanised as standard. In our own plant, the Sigma beams are surface treated to withstand great stress. The method provides a very robust protection against corrosion. For more information, please visit our page for surface treatment.
