Architectural Glulam Beams
Glulam Beams are 2x4 or 2x6 Douglas Fir dimensional lumber layered and laminated together with durable, moisture-resistant structural adhesives. By laminating a number of smaller pieces of timber, a single large, strong, structural member is manufactured from smaller pieces.
