UNSPSC 11122000: Engineered wood products

A range of derivative wood products which are manufactured by binding together the strands, particles, fibers, or veneers of wood, together with adhesives, to form composite materials. These products are engineered to precise design specifications which are tested to meet national or international standards.

UNSPSC 11122000 Engineered wood products is a Class code representing pressure-treated lumber, dimensional framing materials, roofing components, and structural hardware that state and local governments purchase for building maintenance, site improvements, park infrastructure, and facility rehabilitation projects. Recent solicitations show counties and municipalities sourcing pressure-treated pine lumber in standard dimensions (2"×4" through 8"×8", lengths 8' to 16'), deck screws and structural fasteners, joist tape, deck boards, roofing sheathing (7/16-inch oriented-strand board), architectural asphalt roofing, aluminum gutters and downspouts, treated-wood posts and beams, pergola joists with hardware, and related fastening systems. Work spans routine maintenance (gutter replacement, pergola replacement) and larger capital projects (restroom building construction, facility improvements).
