When you place an order, we then order the lumber for your project. Most of the material we glue is nominal 1” or 2” thick Southern Yellow Pine or Douglas Fir lumber (1”x6”, 2”x8”, 2”x12”, etc.), although we do occasionally glue other wood species. As its name suggests the Southern Yellow Pine comes from tree farms in the southern states, mostly in Arkansas, Georgia and Alabama. We source the Douglas Fir from western states such as Oregon and Washington.
We can glue pressure-treated Southern Yellow Pine material for use in outdoor and marine applications. We are also proud to be Forest Stewardship Council® (FSC) Chain-of-Custody certified for purchasing, manufacturing and selling FSC pure and FSC mixed lumber in our custom glulam material. Many of our customers choose to use FSC certified material if they are looking to achieve a Leadership in Energy and Environmental Design (LEED) Green Building Rating on their project.
The material arrives by truck, or very infrequently rail, and each piece must be visually inspected on our grading chain. Here is a photo of the grading chain.
Una-Lam is a member of the American Institute of Timber Construction (AITC) and the employees on the grading chain are trained to inspect and classify the lumber according to AITC standards. Some of the things they are looking for are moisture content, density and any cosmetic defects in the material. All of these characteristics determine how the lumber can be used in our production process.
After we have graded the material, it is sorted and stacked together and transferred to our lumber yard where it will wait until we pull it out for your job. You may see the grade markings on lifts of lumber in our yard, C for clear boards, O for strong outside plies, W for wane (the edge of the tree), etc. Most of the material in our lumber yard, shown in the photo below, was ordered and will be used on a job going through our plant shortly.
