UNSPSC 31331201: Aluminum bolted structural assemblies

UNSPSC 31331201 Aluminum bolted structural assemblies is a Commodity code that encompasses aluminum structural components and fastening systems used in construction and infrastructure projects. State and local governments procure these materials primarily for bridge construction, pedestrian infrastructure, and facility upgrades where aluminum bolted assemblies serve as primary or secondary structural components. Recent solicitations show demand concentrated in public works departments managing capital bond-funded projects and universities acquiring metals for operational and construction needs. The City of San Antonio Capital Delivery Department and Sarasota County have been active buyers, with Sarasota County's Midnight Pass Road pedestrian bridge project specifically calling for structural steel and concrete work (though tagged to this aluminum code), and San Antonio's infrastructure and facility projects funded through 2022 Bond programs.

Recent activity spans Texas and Florida, with additional procurement sourcing from Wisconsin. The City of San Antonio Capital Delivery Department posted RFCSP2026025 for the Hays Street Bridge Connections & Eastside Area Streets project on July 8, 2026, with a competitive sealed proposal due August 25, 2026 covering roadway improvements and creek greenway extension work; the department also posted RFCSP2026071 for Fire Station #33 Facility Replacement on June 15, 2026, with proposals due July 30, 2026. Sarasota County issued IFB 262861MN for the Midnight Pass Road Pedestrian Bridge on June 17, 2026, with bids due July 20, 2026, covering steel truss bridge deck and concrete pile construction.
