UNSPSC 31331211: Waspalloy bolted structural assemblies

UNSPSC 31331211 Waspalloy bolted structural assemblies is a Commodity code that in recent state and local solicitations covers structural steel components for bridge and building construction projects—specifically steel truss members, connection assemblies, and related structural shapes used in pedestrian bridges and facility construction. The recent opportunities tagged under this code show structural steel as a component product line within larger construction contracts rather than as a standalone fastener or specialty-alloy procurement. Issuing bodies include municipal government (City of San Antonio Capital Delivery Department) and county government (Sarasota County), both soliciting construction contracts that incorporate structural steel as a major scope element. These are general-jurisdiction construction buyers, not specialized procurement offices targeting metallurgical or aviation-grade alloy suppliers.

Activity concentrates in Florida and Texas. Sarasota County posted an Invitation for Bids (IFB) on July 29, 2026 for the Midnight Pass Road Pedestrian Bridge, a steel truss bridge project with a response deadline of July 27, 2026, scope including deck, piles, end bents, and approach slabs. The City of San Antonio Capital Delivery Department issued two competitive sealed proposal requests: RFCSP2026025 for Hays Street Bridge Connections & Eastside Area Streets (posted July 8, 2026; proposals due August 25, 2026 at 2:00 p.m. Central Time, with a pre-submittal conference July 20, 2026), and RFCSP2026071 for Fire Station #33 Facility Replacement (posted June 15, 2026; proposals due July 30, 2026 at 2:00 p.m. Central Time, with mandatory site visit June 29, 2026). Both San Antonio projects are funded through the 2022 Bond program and include structural shapes and building construction materials. The code shows limited recent activity; the three opportunities represent construction contracts in which structural steel is a component rather than a primary procurement focus.
