Glue Laminated Building Columns

Glulam, short for glued laminated timber, is an engineered wood product. Large glulam members are produced from smaller pieces of stress graded and seasoned timber, known as laminates.

Glulam offers many benefits when it comes to structural applications:
Large section sizes and long lengths - glulam can be manufactured curved or straight and is often used a structural beams. Finger jointing allows for long lengths.

Increased strength due to the laminating process - glulam is stronger that solid timber as it has fewer natural defects and a wider distribution. It is also comparable to steel in strength but is much lighter.

A high degree of dimensional stability - glulam is manufactured from seasoned timber and therefore less prone to movement caused by changes in moisture content. Care needs to be taken if they are used externally or in an environment with rapidly changing humidity. Swelling and shrinkage may lead to splitting or, in an extreme event, delamination of the beam.

Reliability - glulam is manufactured to strict quality requirements from stress-graded timber of known structural capacity.

Laminated Veneer Lumber (LVL) LVL is a high-strength engineered wood product. Comparable in strength to solid timber, concrete and steel and is manufactured by bonding together rotary peeled or sliced thin wood veneers under heat and pressure. Used for permanent structural applications including beams, lintel, purlins, truss chords and formwork.
Ponderosa and Sugar Pine Most commonly used of western soft woods. Excellent workability and texture for ease of use. Pine is a favorite wood to choose for a variety of patterns.
Douglas-Fir One of the best western woods. Used in manufacturing of more products than any other wood species. Reliable and workable.
Incense-Cedar Recognized for its resistance to decay. Sweet smelling wood is specially kiln dried to insure dimensional stability. Superb for patterns.
California White Fir One of the most versatile soft woods in America. Non-resinous, fine textured, mills accurately, and remains straight. Widely used in residential and light commercial construction.
Western Hemlock Characteristics similar to White Fir.
