Duo-trio beams are manufactured from spruce lamellas. Duo/trio beams consist of two (duo) or three (trio) timber lamellas glued together. Moisture content is %12-/+ %3 and with this moisture the swelling of the duo-trio beams are prevented. Due to the Finger Jointing system longer parts for every type of construction plansa re easily manufactured.

The high structural stability of massive laminated beams give the chance to be calculated easily and also give perfect results in optical view. It’s a high quality product and is easy to maintain.

Laminated Beams can be used as roof and ceiling beams, roof purlins and in all areas of private and industrial buildings.

1) Visible quality products with less knot surface view are used at visible and inner parts of the buildings.

2) Invisible quality are more knotty products on the surface. It’s generally used among the roof. The difference between Glulam and DuoTrio beams is tha the Glulam Beams have 40 mm lamella thickness. Duo-Trio beams may have lamella’s with different thicknesses.
