Mar-Span: your supplier for all Floor & Roof Applications.

LPI Joists are engineered to be straighter, stiffer and provide more consistent performance than solid sawn lumber joists. In essence, we've taken the tree apart and, with sophisticated manufacturing, put it back together to outperform traditional lumber products. LPI Joists reduce the problems that occur as solid sawn lumber joists dry. They are less likely to shrink, split, twist, warp or crown, resulting in high quality floors and ceilings that are solid and uniform.

ENGINEERED FOR STRENGTH
Mechanically graded, finger-jointed, kiln dried lumber make up the top and bottom flanges of the LPI 20 20X and 32 series I-joists. Every flange is proof tested to ensure strength and quality. The webs, which allow plumbing and wiring to pass through without extra framing, are made of strong. Stable oriented strand board. Pound for Pound, LPI Joists have more load-bearing capacity than dimensional lumber, so floors and ceilings can be designed with fewer pieces, saving installation and material costs.

AN ENVIRONMENTALLY SOUND CHOICE
In addition to excellent performance, LPI Joists are a smart choice for building because they are made from a renewable resource: trees. In addition, their increased load-bearing capacity can result in wider spacing between joists, further maximizing the use of a valuable natural resource.
