By laminating several smaller pieces of wood, a single large, strong, structural member is manufactured from smaller pieces. These structural members are used as vertical colums or horizontal beams, as well as curved, arched shapes. In fact, glulam is the only engineered wood product that can be produced in curved shapes, offering unlimited design flexibility. It is available in a range of appearance characteristics to meet end-use requirements.
Connections are usually made with bolts or plain steel dowels and steel plates.
Glulam Products.
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.
What Is Glulam?
Glulam is composed of individual wood laminations, or “lams”, specifically selected and positioned in the timber, based on their performance characteristics, and bonded together with durable, moisture-resistant adhesives. Glulam is available in depths from 6 to 72 inches or greater and in lengths up to 100 feet and longer.
Laminated products are a proven technology where graded pieces of timber, either finger jointed or solid, are bonded together with structural glue whilst being held under pressure until cured.
These beams are manufactured from H3.2 CCA Service Class 3 timber treated prior to laminating. This technique ensures 100% penetration of the wood preservative. These beams are manufactured to recognised standards.
Designed for Long Life
Being H3.2 CCA Service Class 3 treated, the beams are certified for exposure to the weather above ground, or protected from the weather in a situation at risk of moisture entrapment.
Flexible Construction Options
In circumstances, where treatment is required Protim Osmose wood preservative is usedTthere is no limitation on cutting or slotting of the beam to complete construction as long as Osmose end grain concentrate is used.
In addition, there is no requirement to use time consuming and expensive stirrups or other isolating devices.
Uses
Often used for the construction of verandas, pergolas and light roofs.
Laminated Beams are ideal where superior construction properties are required combined with “Peace Of Mind” durability.
