UNSPSC 31331209: Stainless steel bolted structural assemblies

UNSPSC 31331209 Stainless steel bolted structural assemblies is a Commodity code that encompasses structural steel components and assemblies procured for bridge construction, building frameworks, and similar infrastructure projects. State and local governments buying under this code are primarily acquiring steel truss components, connection assemblies, and related structural elements that form the primary load-bearing systems in public works. The issuing bodies soliciting related work are county transportation authorities and municipal capital delivery departments, which contract for design-build or design-bid-build infrastructure projects where steel structural assemblies are specified components. These buyers issue construction-focused solicitations (typically IFBs and RFPs) that name structural steel and bolted assemblies as line items or integral parts of larger facilities or transportation projects.

Recent activity centers on Florida and Texas. Sarasota County posted IFB 262861MN in July 2026 for construction of a steel truss pedestrian bridge on Midnight Pass Road, with a response date of July 20, 2026 (note: the posted date of July 29, 2026 post-dates the due date, indicating a closed opportunity). The City of San Antonio Capital Delivery Department issued two major RFPs in mid-2026: RFCSP2026025 for the Hays Street Bridge Connections & Eastside Area Streets project (proposals due August 25, 2026, pre-submittal conference July 20, 2026) and RFCSP2026071 for Fire Station #33 Facility Replacement (proposals due July 30, 2026, mandatory site visit June 29, 2026). Both San Antonio projects specify structural shapes and site work as applicable categories and are funded through the 2022 Bond program. Written questions on the Hays Street and Fire Station projects route through Jose Narvaez, Procurement Specialist III, with cutoffs at July 28, 2026 and July 14, 2026 respectively. All three opportunities use digital submission portals (CivCastUSA for San Antonio; details for Sarasota County available in posted solicitation documents).
