After that, there was the option of #1 select fir joists.

Prior to 2019, the only option for a deck that is as flat as the floors inside your home was steel frame deck construction. This offers the professional deck builder the ability to eliminate the waviness that can occur in traditional lumber framed decks. With LVL now being offered with pressure treatment, it is approved for outdoor decks. ![]() Laminated veneered lumber provides uniform widths and strength, as well as the elimination of shrinkage and twisting typically found in traditionally milled, forest-grown wood lumber. The beauty of LVL is it is built to engineered specifications in a factory. LVL is not new, it has been a staple of indoor and unexposed building construction for years specifically for headers, beams, rim boards, and columns. And then the introduction of 2nd generation capped composites have we seen a game-changer such as this: pressure-treated Laminated Veneered Lumber or LVL joists for outdoor deck construction.

It’s not too often that an industry such as deck building can say with all confidence that a newly introduced product will truly be a game-changer.
