Glued laminated framework
G-L Industries

Glulam has been called the grandfather of engineering wood, because the first glulam engineered timber was produced over a century ago....log before I Joists of LVL.
Today, glulam is still a fresh choice for designers because of its strength, economy and ambiance. Straight, tapered or curved, it can be ordered in a range of sizes for all types of applications. Its strength for long spans can provide unobstructed view with minimal need for columns or posts.
Glued laminated wood arches, beams and trusses are also a renewable resource, because US foresters plant 5 million trees each day to insure a future supply of wood. this contrasts with steel and concrete, which deplete natural resources.
The combination of high strength and large sizes makes glulam timbers ideal as main load carrying members which can span over 100 feet. In residential construction, glulam beams are commonly used for headers and beams supporting large portions of floor and roof systems.
When glulam materials arrive at the jobsite prefinished or pre-drilled , the delivered product is the finished product. this makes glulam unique as a structural component for many kinds of buildings. other types of framing members arrive on site in raw form, and require additional cladding to create the final production.
Glulam timbers are available in four appearance grades; premium, architectural, industrial and framing.
