Concrete Lumber is a patented stress-reinforced structural cementitious composite that is strong, chemical free and low maintenance. It is an affordable outdoor alternative to wood, steel, composites, LVL and glulams. Concrete Lumber requires basic woodworking skills for installation and can be cut, drilled and screwed using a circular saw with masonry blades and a power drill using masonry bits. When joistloaded, (1.5" thick) Concrete Lumber spans 10% to 20% greater than the same size wood joist. When plank loaded, the same size (1.5" thick) Concrete Lumber plank can span 3 times greater than the same size wood plank and 4 times greater than same size composite plank. Whenplank loaded, the next thickness (3.5" thick) Concrete Lumber plank spans 5 times greater than a (1.5" thick) wood plank and 7 times greater than a (1.5" thick) composite plank. Click Here to see a (3.5") thick Concrete Lumber plank with a one-ton uniform load having clear span of 10 feet and only 0.25" deflection. Concrete Lumber is splinter free and fire resistant, will not warp, burn, delaminate, rot or be attacked by insects. Concrete Lumber joists, posts, beams and planks are made in dimensional lumber sizes for easy assembly using galvanized or stainless steel fasteners and connectors.

Concrete Lumber uses are endless including timbers, lintels, louvers, baffles, stair treads and trusses, and when properly installed Concrete Lumber will outlast other construction materials. Concrete Lumber can be coated or stained in virtually any color or surface. Click Here for coatings.
