UNSPSC 31331301: Aluminum sonic welded structural assemblies

UNSPSC 31331301 Aluminum sonic welded structural assemblies is a Commodity code with minimal recent relevant activity in state and local procurement. The three construction-related opportunities posted since mid-June 2026 (two from San Antonio and one from Sarasota County) involve structural steel, concrete, and general building construction but do not specify aluminum sonic welded assemblies as line items. The University of Wisconsin-Madison RFB for metals procurement (2026-UWMSN-01207-RFB, due April 20, 2026) names aluminum among materials sought but provides no detail on assembly type or sonic welding specifications. State and local governments appear to source structural aluminum components through broader construction contracts and general metals procurement vehicles rather than as discrete aluminum sonic welded assembly products.

Recent opportunities in this code show activity concentrated in Texas (San Antonio's Hays Street Bridge Connections & Eastside Area Streets project, RFCSP2026025, RFP due August 25, 2026; San Antonio Fire Station #33 Facility Replacement, RFCSP2026071, RFP due July 30, 2026) and Florida (Sarasota County's Midnight Pass Road Pedestrian Bridge, IFB 262861MN, due July 20, 2026), with a broader metals-sourcing RFB at University of Wisconsin-Madison. The City of San Antonio Capital Delivery Department appears as a repeat buyer, issuing two major capital-delivery RFPs within weeks of each other. However, none of these solicitations explicitly call out aluminum sonic welded assemblies, suggesting the code does not currently align closely with what state and local agencies are actually procuring under their recent notices.
