UNSPSC 31331212: Copper bolted structural assemblies

UNSPSC 31331212 Copper bolted structural assemblies is a Commodity code that in recent state and local solicitations encompasses structural metal components for infrastructure and construction projects, including steel structural elements, truss systems, and related bolted assemblies used in bridge construction, roadway improvements, and building projects. State and local issuing bodies soliciting under this code include municipalities (City of San Antonio), counties (Sarasota County), and public universities (University of Wisconsin-Madison). The scope of work reflects broad structural steel and metal procurement across transportation, facilities, and infrastructure capital projects, with applications ranging from pedestrian bridge trusses to building construction framing and site work components.

Recent activity concentrates in Texas and Florida, with representation from Wisconsin. The City of San Antonio Capital Delivery Department has posted multiple large construction RFPs including the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025, proposals due August 25, 2026) and Fire Station #33 Facility Replacement (RFCSP2026071, proposals due July 30, 2026), both funded through the 2022 Bond program and encompassing structural shapes and building construction components. Sarasota County solicited construction of a steel truss pedestrian bridge on Midnight Pass Road through an IFB (262861MN, bids due July 20, 2026), specifying a steel truss bridge deck and related structural elements. The University of Wisconsin-Madison posted an RFB for metals including steel, aluminum, and stainless steel (2026-UWMSN-01207-RFB, bids due April 20, 2026) with responses submitted through ShopUW+ procurement portal. The code shows mixed issuing-body activity across municipal construction, county transportation infrastructure, and higher-education facilities procurement.
