UNSPSC 31331701: Aluminum riveted structural assemblies

UNSPSC 31331701 Aluminum riveted structural assemblies is a Commodity code that in state and local procurement covers structural metal components and assemblies used in infrastructure and building projects. The recent opportunities show that state and local buyers are soliciting structural steel and aluminum materials and components primarily for bridge construction, roadway improvements, and facility construction. Issuing bodies include city capital delivery departments, county governments, and universities. The City of San Antonio Capital Delivery Department appears as a repeat buyer, posting proposals for the Hays Street Bridge Connections & Eastside Area Streets project and Fire Station #33 Facility Replacement in June and July 2026, both funded through the 2022 Bond. Sarasota County has posted a steel truss pedestrian bridge construction IFB, and the University of Wisconsin-Madison issued an RFB for metals procurement including aluminum and steel materials in March 2026.

Recent activity concentrates in Texas and Florida. The San Antonio proposals (RFCSP2026025 due August 25, 2026, and RFCSP2026071 due July 30, 2026) represent municipal infrastructure and facility work encompassing structural shapes and components. Sarasota County's Midnight Pass Road Pedestrian Bridge IFB (solicitation 262861MN, due July 20, 2026) specifies a steel truss bridge deck and concrete construction with associated structural work. The University of Wisconsin-Madison RFB (2026-UWMSN-01207-RFB, due April 20, 2026) sought direct metal supply rather than assembled components. The code shows moderate but meaningful activity in construction-related procurement across municipal and regional buyers in the Southwest and Southeast.
