Glulam Beams & Columns

Glued laminated timber, or glulam, is a highly innovative and versatile construction material engineered for a host of residential and commercial construction applications. Increased design values and improved product performance make this cost competitive material the natural choice for every project from simple beams and headers in residential construction to soaring glulam arches for domed stadium roofs spanning more than 500 feet.

Glued laminated timber (glulam) is made up of wood laminations, or "lams," that are bonded together with adhesives. The grain of all laminations runs parallel with the length of thte member. Individual lams typically are 1-3/8 inches thick for southern pine and 1-1/2 inches thick for Western species, although other thicknesses may also be used. Glulam products typically range in net widths from 2-1/2 to 10-3/4 inches, although virtually any width can be custom produced.
