UNSPSC 31331201: Aluminum bolted structural assemblies

UNSPSC 31331201 Aluminum bolted structural assemblies is a Commodity code that captures structural steel and aluminum framing components used in infrastructure construction, though recent state and local solicitations under this code predominantly feature steel truss bridges and structural shapes for building construction rather than aluminum assemblies specifically. State and local governments buy structural components through this code as part of larger infrastructure and facility projects—typically procured as design-build or full-scope construction contracts where structural framing is one line item among many. The issuing bodies soliciting under the code include county governments and municipal capital delivery departments, particularly in Texas and Florida based on recent activity, with the City of San Antonio appearing as a repeat buyer across multiple bond-funded construction initiatives.

Sarasota County, Florida posted an IFB in July 2026 for a steel truss pedestrian bridge on Midnight Pass Road with bids due July 27, 2026, covering steel truss bridge deck, prestressed concrete piles, concrete end bents, and approach slabs. The City of San Antonio Capital Delivery Department has posted two competitive sealed proposals for construction services: the Hays Street Bridge Connections & Eastside Area Streets project (RFP due August 25, 2026) encompassing roadway and creek greenway improvements with structural shapes and concrete beams, and Fire Station #33 Facility Replacement (RFP due July 30, 2026) involving a new facility at 2935 Castroville Road with structural components as part of the full construction scope. Structural aluminum and steel bolted assemblies appear in these solicitations as components of larger infrastructure projects rather than standalone procurements, with Florida and Texas showing the most recent competitive activity in this commodity space.
