Laminated wood beams in high quality

Our DUO/TRIO beams are ideally suited as visible components. They are clearly more stable than solid wood and the static values are also somewhat better. We use Nordic raw materials in the appropriate dimensions where you can see them. For the stronger cross-sections we get specially cut central European material that we have also pre-sorted. As a result, we can offer consistently, high quality.

We also provide the beams for the non-visible area (industrial quality) in all commercially available dimensions.

Made to measure dimensions

We provide laminated wood beams within these ranges:

- Thickness: 60-240 mm
- Width: 80-280 mm
- Length: up to max. 15 m

Safety of the wood components

We achieve the reliable surface bonding with formaldehyde-free PUR-glue in a state-of-the-art in a state-of-the-art processing technology.

Like all of the other structural wood components that we manufacture, the duo and trio beams also meet the current standards. The University of Stuttgart has confirmed the proper gluing of the laminated wood beams through regular tests.
