UNSPSC 31341106: Non metallic welded or brazed sheet assemblies

UNSPSC 31341106 Non metallic welded or brazed sheet assemblies is a Commodity code that in practice captures structural steel components and assemblies used in bridge construction and heavy civil infrastructure projects. State and local governments buy fabricated steel deck systems, truss assemblies, connection plates, and related welded or brazed subassemblies as components of larger construction contracts. The issuing bodies soliciting under this code include county governments and municipal capital delivery departments, typically procuring through construction RFPs, RFQs, and IFBs that bundle structural steel fabrication and installation with site work, concrete, and finishing trades. The work is let as part of single general-contractor awards that incorporate the steel components into the full project scope rather than as standalone material-supply contracts.

Recent activity clusters in Texas and Florida. Sarasota County posted an IFB in July 2026 for construction of a steel truss pedestrian bridge on Midnight Pass Road, with bids due July 27, 2026, comprising a steel truss bridge deck, prestressed concrete piles, concrete end bents, approach slabs, and sidewalks. The City of San Antonio Capital Delivery Department has posted multiple construction RFPs funded through the 2022 Bond program, including the Hays Street Bridge Connections & Eastside Area Streets project (due August 25, 2026) encompassing a creek greenway extension with bridge and roadway improvements, and Fire Station #33 Facility Replacement (due July 30, 2026) for a new fire station at 2935 Castroville Road. San Antonio's solicitations identify applicable NIGP categories including structural shapes, concrete beams, and building construction, with pre-submittal conferences, mandatory or optional site visits, and questions cycles structured through the CivCastUSA portal.
