Duo- and Trio-laminated beams
Duo- and Trio-laminated beams comprise two or three lamellae, pith side out and glued together.
The rigid bonding of the elements means that these beams hardly crack or twist even after very long periods. They are perfect material for exceptionally stable and high quality timber construction.
The classic character of the beam and appearance of solid wood are well preserved. They have excellent characteristics as a building material for exposed ceiling beams and rafters.
Duo and Trio beams are produced in standard cross sections. The advantages of standardisation for trade and the processing industry are obvious: produced as stock, short delivery times, economic planning and construction.
On top of this we are able to produce Duo and Trio beams on your demand: flexible, individual and fast.
- Dimensionally stable timber construction
- Maximum load-bearing capacity – equal to GL24 glulam
- Stability and attractive appearance
- Usage in exposed and concealed areas
