UNSPSC 31331709: Stainless steel riveted structural assemblies

UNSPSC 31331709 Stainless steel riveted structural assemblies, a Commodity code, covers fabricated structural steel components and subassemblies used in bridge and building construction projects. State and local procurement under this code centers on steel truss elements, connection assemblies, and integrated structural components that form part of larger infrastructure delivery contracts. Recent solicitations show that cities and counties procure these assemblies as part of competitive general construction contracts for pedestrian bridges, roadway structures, and facility replacements, where the steel fabrication and assembly work is bundled within broader IFB or RFP scopes rather than solicited as standalone component supply. Issuing bodies include county transportation and capital departments, municipal capital delivery offices, and public works authorities in Florida and Texas that manage bond-funded infrastructure programs.

Recent activity concentrates in Florida and Texas. Sarasota County issued an IFB (262861MN) in July 2026 for construction of a steel truss pedestrian bridge on Midnight Pass Road, with bids due July 20, 2026, incorporating steel truss deck elements as part of the overall project scope. The City of San Antonio Capital Delivery Department posted two construction RFPs in June and July 2026 — RFCSP2026071 for Fire Station #33 Facility Replacement (proposals due July 30, 2026) and RFCSP2026025 for the Hays Street Bridge Connections & Eastside Area Streets project (proposals due August 25, 2026, with a pre-submittal conference on July 20, 2026) — both funded through 2022 Bond programs and both listing structural shapes and building construction as applicable material categories. These opportunities indicate that stainless steel riveted structural assemblies are purchased primarily as integrated components within larger construction delivery contracts rather than as discrete procurements.
