Parallam Plus PSL

Trus Joist Parallam Plus PSL, with Wolmanized preservative protection, addresses multiple exposed structural lumber applications. Our strong and longer engineered lumber components enable greater design flexibility and deliver long-term durability even in the harshest conditions.

Decay – and insect-resistant Parallam Plus PSL headers, beams, columns, and posts in a variety of standard dimensions are perfect for framing decks, retaining walls, carports, pool enclosures, and outdoor shelters, among other structural framing applications where the wood comes in direct contact with the ground or moisture.
