Compound of () ('part; section') and (ざい) ('material; timber'). Refers to individual pieces that are combined to form a structure or product. The word sits between raw materials and finished products — a 部材(ぶざい) has already been shaped or prepared but has not yet been assembled into the final structure.

USAGE:
Common in construction, architecture, and manufacturing contexts. Often appears in technical documents, building regulations, and product catalogs. Can refer to materials of any kind — wood, steel, concrete, plastic — as long as they serve as components of a larger assembly.
