UNSPSC 31331409: Stainless steel ultra violet welded structural assemblies

UNSPSC 31331409 Stainless steel ultra violet welded structural assemblies is a Commodity code that in recent state and local procurement activity covers structural steel and metal materials for construction projects, including steel truss bridges, structural shapes for building and infrastructure work, and general metals procurement. State and local issuing bodies soliciting under this code include municipal capital delivery departments, county engineering offices, and universities. The City of San Antonio Capital Delivery Department appears as a repeat buyer, posting multiple construction RFPs in 2026 that reference structural shapes and site work applicable to the code's scope.

Recent activity appears concentrated in Texas and Florida, with the City of San Antonio posting two major RFPs—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)—and Sarasota County soliciting construction bids for the Midnight Pass Road Pedestrian Bridge under IFB format (due July 20, 2026). The University of Wisconsin-Madison posted a broader metals procurement RFB (2026-UWMSN-01207-RFB, due April 20, 2026) for steel, aluminum, and stainless steel materials. The San Antonio projects emphasize site work and structural components for capital improvements funded through the 2022 Bond; the Sarasota County project focuses on steel truss bridge deck construction with concrete foundations; the University of Wisconsin solicitation targets materials supply rather than fabricated assemblies.
