UNSPSC 31331609: Stainless steel welded or brazed structural assemblies

UNSPSC 31331609 Stainless steel welded or brazed structural assemblies is a Commodity code that in recent state and local procurement activity covers steel structural components and assemblies incorporated into infrastructure projects—primarily steel truss bridges and structural steel elements for building construction. The issuing bodies are municipal and county governments, with the City of San Antonio and Sarasota County appearing as active buyers in the recent opportunity set. Work includes fabrication and/or integration of steel structural frames, trusses, and related assemblies as part of larger construction contracts, typically awarded through competitive sealed proposals (RFP/RFQ) or invitations for bids (IFB) for fixed-price construction delivery.

Recent opportunities cluster in Texas and Florida. Sarasota County, Florida issued an IFB (Solicitation 262861MN) for construction of a steel truss pedestrian bridge on Midnight Pass Road with bids due July 20, 2026; the scope explicitly names a steel truss bridge deck as the primary structural element. The City of San Antonio Capital Delivery Department issued an RFP (RFCSP2026025) for the Hays Street Bridge Connections & Eastside Area Streets project with proposals due August 25, 2026, which encompasses bridge and roadway work involving structural shapes and building elements; a second San Antonio RFP (RFCSP2026071) for Fire Station #33 Facility Replacement, due July 30, 2026, includes structural shapes among applicable product categories for new-construction delivery. Pre-submittal conferences and site visits are common—San Antonio required a mandatory site visit and pre-submittal briefing for both active solicitations.
