UNSPSC 31331113: Brass bonded structural assemblies

UNSPSC 31331113 Brass bonded structural assemblies is a Commodity code that in practice captures structural metal components and fastening assemblies used in civil infrastructure and building construction — though recent state and local solicitations show limited direct procurement under this specific code designation. The code appears in infrastructure projects involving bridge construction, roadway work, and facility replacement where structural connections and bonding assemblies form part of the broader construction scope. State and local buying under this code flows through capital delivery departments, county engineering offices, and university facilities procurement, typically as line-item components within larger construction or materials RFPs and RFBs rather than as standalone solicitations for brass bonded assemblies alone.

Recent activity clusters in Texas and Florida, with secondary university procurement in Wisconsin. The City of San Antonio Capital Delivery Department posted multiple construction RFPs in mid-2026 — including the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025, due August 25, 2026) and Fire Station #33 Facility Replacement (RFCSP2026071, due July 30, 2026) — both citing structural shapes and building construction components within broader scopes. Sarasota County issued an IFB for the Midnight Pass Road Pedestrian Bridge (IFB 262861MN, due July 20, 2026) specifying steel truss, concrete, and approach slab work. The University of Wisconsin-Madison posted a metals RFB (2026-UWMSN-01207-RFB, closed April 20, 2026) for steel, aluminum, and stainless steel materials. The code shows modest recent activity; brass bonded assemblies are typically specified as subordinate components within larger construction contracts rather than as primary procurement objects.
