UNSPSC 31331209: Stainless steel bolted structural assemblies

UNSPSC 31331209 Stainless steel bolted structural assemblies, a Commodity code, encompasses structural steel components and assemblies used in bridge construction, building frameworks, and infrastructure projects by state and local governments. Recent solicitations show state and local agencies buying structural steel materials and components for construction work rather than finished bolted assemblies per se — the code activity reflects how procurement systems tag steel structural work during infrastructure delivery. Issuing bodies include city capital delivery departments, county governments, and public universities, with the City of San Antonio Capital Delivery Department appearing as a repeat buyer. The work involves supplying or integrating structural steel elements into larger construction projects including pedestrian bridges, roadway improvements, and facility replacements funded through municipal bonds and operational budgets.

Recent activity clusters in Texas and Florida, with secondary activity in Wisconsin. The City of San Antonio Capital Delivery Department posted competitive sealed proposals for the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025, due August 25, 2026), covering creek greenway and roadway improvements where structural shapes and site work are applicable categories, with a pre-submittal conference on July 20, 2026. Sarasota County solicited construction bids for the Midnight Pass Road Pedestrian Bridge (262861MN, IFB format, due July 20, 2026), explicitly including steel truss bridge deck and structural components. The City of San Antonio also posted proposals for Fire Station #33 Facility Replacement (RFCSP2026071, due July 30, 2026), where structural shapes appear in the applicable product scope. The University of Wisconsin-Madison issued an RFB for metals procurement including steel and stainless steel (2026-UWMSN-01207-RFB, due April 20, 2026), though this represents materials supply rather than structural assembly services.
