When to use: Non-finish structural and utility wood framing and blocking. Covers dimension lumber framing (studs, plates, sills, joists, rafters, headers, ledgers); species, grade, and grade stamps under an ALSC-accredited grading agency and the National Grading Rule; design values per the AWC NDS; moisture content (S-DRY / MC19 / KD); wall, roof, and floor sheathing in plywood (DOC PS 1) and OSB (DOC PS 2) with APA span ratings and Exposure 1 bond classification; wood structural panel attachment and nailing; rooftop blocking, nailers, cant strips, curbs, and concealed wood grounds and furring; pressure-preservative-treated wood per the AWPA Use Category System and the IBC locations that require it; fire-retardant-treated (FRT) wood for interior Type III, IV, and V applications; and corrosion-resistant fasteners and metal framing connectors (joist hangers, framing anchors, post bases) compatible with treated wood and exterior service.
− Not intended for: Finish and architectural millwork ([[syncs/architectural-wood-trim-and-paneling]]); casework ([[syncs/wood-and-laminate-casework]]); shop-fabricated structural glued-laminated timber, cross-laminated timber, and other mass timber and engineered wood products; prefabricated wood trusses; cold-formed steel framing ([[syncs/cold-formed-metal-framing]]); and concrete formwork lumber.
