GLULAM WOODEN TRUSS
Glued laminated timber, or glulam, is a highly inventive construction material. Pound for pound, glulam is stronger than steel and has better strength and stiffness than comparably sized dimensional lumber. Increased design values, improved product performance, and cost competitiveness make glulam the better choice for projects from simple beams and headers in residential construction to soaring arches for domed roofs spanning more than 500 feet.


Glulam is a stress-rated engineered wood beam composed of wood laminations, or "lams", that are bonded together with strong, moisture-resistant adhesives. 


The granule of the laminations runs parallel with the length of the member. Glulam is flexible, ranging from simple, straight beams to complex, curved members. 


Glulam is obtainable in both custom and stock sizes and one of four exterior classifications: premium, architectural, industrial, or framing.
