A large range of sizes, including Doug fir up to 32' long. Download a complete list of stock lumber.

Engineered Wood Products

I-Joists - Engineered floor joist consisting of a web sandwiched by flanges to make the "I" shape. The advantage of I-joists is they will not bow, crown, twist, cup, check, or split as would a dimensional piece of lumber. Also, I-joists are designed to help eliminate squeaky floors by being more dimensionally sound and little to no shrinking.

Laminated Veneer Lumber (LVL) - Consist of multiple layers of thin wood held together with adhesives. It is stronger and stays straighter than conventional lumber. Common uses - Headers and Beams.

Glu-Lam - Multiple pieces of smaller lumber (typically 2x4's or 2x6's) laminated together to form a larger beam used as support beams or vertical columns.
