UNSPSC 31331401: Aluminum ultra violet welded structural assemblies

UNSPSC 31331401 Aluminum ultra violet welded structural assemblies (Commodity) appears in state and local procurement primarily as a secondary component specification within broader construction and infrastructure projects rather than as a primary procurement category. The recent opportunities show structural aluminum assemblies being requested as part of larger scopes that include site work, concrete, steel, electrical, HVAC, and general building construction. The code shows minimal standalone demand; when aluminum assemblies are specified, they are typically embedded within RFP or IFB packages for complete facility construction or bridge projects. State and local issuing bodies soliciting under this code include municipalities (city capital delivery departments) and counties, with no evidence of school districts, transit authorities, or state departments driving activity in this specific commodity.

The code sees recent activity concentrated in Texas and Florida, driven by capital bond programs and infrastructure improvement initiatives. Representative opportunities include the City of San Antonio Capital Delivery Department's competitive sealed proposal for Fire Station #33 Facility Replacement (RFCSP2026071, RFP, due July 30, 2026), which lists structural shapes and building construction among applicable categories, and Sarasota County's IFB for the Midnight Pass Road Pedestrian Bridge (262861MN, due July 20, 2026), specifying steel truss and concrete components. A third San Antonio solicitation, Hays Street Bridge Connections & Eastside Area Streets (RFCSP2026025, RFP, due August 25, 2026), similarly bundles structural elements with site work and roadway improvements. A University of Wisconsin–Madison RFB for metals procurement (2026-UWMSN-01207-RFB, due April 20, 2026) lists aluminum among steel and stainless steel materials but provides no detail on welded assemblies specifically. The code shows no broad geographic spread beyond these isolated recent instances; activity appears episodic rather than systematic.
