UNSPSC 31331101: Aluminum bonded structural assemblies

UNSPSC 31331101 Aluminum bonded structural assemblies, a Commodity code, covers structural components and assemblies used in construction projects, though recent state and local solicitations show that the code is being applied primarily to steel truss and concrete structural work rather than aluminum-specific products. State and local governments buying under this code are soliciting construction services for bridges, greenway extensions, and facility replacements that incorporate structural framing, load-bearing assemblies, and bonded connections as components of larger capital projects. Issuing bodies include county governments (Sarasota County) and city capital delivery departments (City of San Antonio), with the latter appearing as a repeat buyer posting multiple bond-funded construction projects in the first half of 2026.

Recent activity concentrates in Florida and Texas. Sarasota County issued an IFB for construction of a steel truss pedestrian bridge on Midnight Pass Road with bids due July 27, 2026, specifying steel truss bridge deck, prestressed concrete piles, and concrete end bents. The City of San Antonio Capital Delivery Department posted two proposals in June and July 2026: RFCSP2026025 for Hays Street Bridge Connections and Eastside Area Streets (roadway and creek greenway improvements, RFP due August 25, 2026) and RFCSP2026071 for Fire Station #33 Facility Replacement (new construction at 2935 Castroville Road, RFP due July 30, 2026), with a mandatory site visit and pre-submittal conference. Both San Antonio solicitations are funded through the 2022 Bond program and required written questions through designated procurement contacts by early July deadlines.
