Glulam Beams

Glue laminated timber or glulam consists of a number of strength timber laminations glued together. This results in a structural unit of great strength and dimensional stability. Glulam can be used in many structural applications such as beams, columns and purlins. Glulam is more sustainable than its steel or concrete beam alternative.
