UNSPSC 31331703: Hastalloy X riveted structural assemblies

UNSPSC 31331703 Hastalloy X riveted structural assemblies is a Commodity code that in practice encompasses structural steel fabrication and assembly work for bridge and building construction projects solicited by state and local public bodies. Recent opportunities show that governments are purchasing steel structural components — including steel truss bridge decks, prestressed concrete elements, and general structural shapes — as part of larger capital infrastructure projects. The issuing bodies include county governments and city capital delivery departments; Sarasota County and the City of San Antonio have each posted multiple opportunities under related structural classifications within the past three months.

Geographic activity centers on Florida and Texas. Sarasota County (Florida) posted an IFB for construction of a steel truss pedestrian bridge on Midnight Pass Road with a due date of July 20, 2026. The City of San Antonio Capital Delivery Department posted two competitive sealed proposals: one for Hays Street Bridge Connections & Eastside Area Streets (due August 25, 2026) encompassing roadway and creek greenway improvements with structural components, and one for Fire Station #33 Facility Replacement (due July 30, 2026) involving new construction with structural shapes and building systems. Both San Antonio projects are funded through the 2022 Bond program. The code shows limited recent activity outside these two states, and the opportunities posted suggest that Hastalloy X riveted assemblies — if sourced at all under this code — are embedded within broader steel structural and general construction contracts rather than procured as standalone commodity items.
