UNSPSC 31331101: Aluminum bonded structural assemblies

UNSPSC 31331101 Aluminum bonded structural assemblies is a Commodity code that in recent state and local procurement primarily covers structural steel and aluminum components for construction projects, including bridge decks, trusses, concrete piles, and end bents. The code appears in solicitations issued by municipalities and counties for infrastructure work, alongside broader materials procurement by educational institutions. The scope spans fabricated structural elements and bonded assemblies used in bridge construction, pedestrian infrastructure, and building projects rather than raw metals alone.

Recent activity comes from Texas and Florida jurisdictions. The City of San Antonio Capital Delivery Department posted two major RFP opportunities in June and July 2026: RFCSP2026071 for Fire Station #33 Facility Replacement (due July 30, 2026) and RFCSP2026025 for the Hays Street Bridge Connections & Eastside Area Streets project (due August 25, 2026), both funded through the 2022 Bond and encompassing structural shapes, concrete elements, and building construction components. Sarasota County issued an IFB in June 2026 (solicitation 262861MN) for construction of a steel truss pedestrian bridge on Midnight Pass Road with a July 20, 2026 deadline, specifying steel truss bridge deck, prestressed concrete piles, concrete end bents, and approach slabs. The University of Wisconsin-Madison posted an RFB in March 2026 (2026UWMSN-01207-RFB) for metals procurement including steel and aluminum materials, due April 20, 2026. Texas municipalities and counties currently drive the highest-profile activity under this code, with infrastructure bond-funded projects dominating the pipeline.
