UNSPSC 31331212: Copper bolted structural assemblies

UNSPSC 31331212 Copper bolted structural assemblies is a Commodity code that captures steel and structural steel components used in bridge and building construction projects, though recent state and local solicitations show primary demand for structural steel shapes, trusses, and bolted assemblies in bridge decks and building frames rather than copper-specific fastening. State and local governments buying under this code are issuing construction RFPs and IFBs for infrastructure projects—pedestrian bridges, roadway improvements, and facility replacements—where structural steel assemblies form the primary load-bearing and connection elements. Sarasota County, the City of San Antonio, and other municipal and county capital-delivery departments represent the typical issuing bodies, each managing bond-funded or general capital projects that incorporate structural-steel work as a major scope component.

Recent activity centers on Florida and Texas. Sarasota County posted IFB 262861MN in July 2026 for the Midnight Pass Road Pedestrian Bridge, a steel truss bridge with prestressed concrete piles and concrete end bents, with bids due July 27, 2026; the City of San Antonio Capital Delivery Department posted two competitive sealed proposals in summer 2026—RFCSP2026025 for the Hays Street Bridge Connections & Eastside Area Streets project (proposals due August 25, 2026) and RFCSP2026071 for Fire Station #33 Facility Replacement (proposals due July 30, 2026), both funded through the 2022 Bond program. These opportunities reflect steady demand for structural-steel procurement in municipal bridge and building construction, typically bundled within larger construction contracts rather than procured separately.
