WQ beams

The WQ beam is intended to speed up the construction of multi-storey buildings. The WQ-beam system can be used in any multi-storey buildings, such as offices, hospitals, hotels and in residential construction.

CWQ beams

Similar to WQ beam, the CWQ composite beam is intended to speed up the construction of multi-storey buildings. The CWQ beam consists of a traditional WQ box beam and dowels combined with it. They form the composite beam structure together with hollow-core slabs and screed. CWQ-composite beam system can be used in any multi-storey buildings, such as offices, hospitals, hotels and in residential construction.

Welded girders

Welded girders can be designed and optimized for different purposes. Welded girders and beams are designed and optimized per project in order to achieve the best possible solution. Welded girders are most commonly fabricated into I-girders (IG) and box girders (BG). Our automated welding lines and advanced production methods ensure fast, high-quality and reliable deliveries. We fabricate and complete each girder ready for installation as required by the client. We take care of the transport of the girders to the construction site and promise to deliver the product in the right place at the right time.

Composite columns

Our composite column consists of a hollow steel section with a rebar cage placed inside. The column is filled with concrete on-site. The combination of steel and concrete provides superior load-bearing capability in normal and fire situations. On-site assembly is fast and the surface of the column is smooth and ready for final coating. Composite columns are designed according to EN-1994-1-1 or local regulations.


Our wide range of trusses are suitable for a variety of uses, the main use being a roof support. The size and shape of a truss vary according to geometrical and loading requirements. Trusses are usually constructed of hollow sections, but other profiles can be utilised if needed. Trusses can be installed on any type of column.
