UNSPSC 31331501: Aluminum solvent welded structural assemblies

UNSPSC 31331501 Aluminum solvent welded structural assemblies, a Commodity code, encompasses structural metal components and fabricated aluminum assemblies used in state and local construction and infrastructure projects. Recent solicitations reveal that government buyers under this code procure structural steel and aluminum components for bridge construction, building facilities, and roadway infrastructure, though the code captures only a portion of broader metal-procurement activity. The issuing bodies include municipal capital delivery departments, county engineering offices, and higher-education institutions. The City of San Antonio's Capital Delivery Department appears as a repeat buyer, soliciting structural components for multiple 2022 Bond-funded projects including bridge connections, pedestrian infrastructure, and facility replacement.

Recent activity concentrates in Texas and Florida. The City of San Antonio issued two major infrastructure RFPs in mid-2026 — RFCSP2026025 for the Hays Street Bridge Connections & Eastside Area Streets project (due August 25, 2026) and RFCSP2026071 for Fire Station #33 Facility Replacement (due July 30, 2026), both incorporating structural-shape and building-construction components. Sarasota County issued an IFB in June 2026 for a Midnight Pass Road Pedestrian Bridge (due July 20, 2026) specifying a steel truss bridge deck and concrete structural elements. The University of Wisconsin-Madison posted an RFB for steel, aluminum, and stainless steel metals in March 2026 (closed April 20, 2026), indicating broader educational and research facility demand. Pre-submittal conferences and mandatory site visits feature in San Antonio solicitations, and written question windows typically close one to two weeks before proposal deadlines.
