Laminated Wood Manufacturing Step by Step

Setra glulam is made from slats which are joined to the larger beams or pillars using the finger-jointing technology. The principle is simple - wooden slats stapled or glued together to form a structural element. 

Finger-jointing

 

First, the slats are cut to the right dimension and dried to the correct moisture level. The slats are then sorted according to strength and are then finger jointed to specified lengths. After the surface is planed, a transparent glue is applied and several slats are glued together under high pressure. After curing the beam is planed and is then ready for packing and transportation.

Certification and Control

Manufacturing of laminated wood requires considerable care in several ways, for example when cutting the finger joints, during the adhesive preparation and application and the pressing stage.

Setra conducts continuous quality checks to ensure consistent high quality of glulam elements. Tests are regularly taken to check strength and durability. In addition to that, SP, (the Swedish Government’s Testing Laboroatory), which is an independent control, perform unannounced visits to all Swedish glulam manufacturers.
