binderholz is a full-range supplier for glulam products. Its core competence lies in the production of straight as well as special shaped beams. Glulam consists of at least 3 timber lamellas glued parallel to the grain. Through grading by strength and homogenization of the timber lamellas, a high level of load-bearing capacity is achieved in comparison to common construction timber. High load-bearing capacity, dimensional stability, product variety and excellent surface quality allow for a broad range of application options in the area of construction.
