UNSPSC 30103500: Honeycomb core

UNSPSC 30103500 Honeycomb core is a Class code that in recent state and local procurement activity actually encompasses structural materials and construction components for infrastructure and building projects—specifically steel, concrete, and metal elements in bridge decks, pedestrian structures, and facility construction rather than the narrower aerospace-composite-focused meaning the code name alone suggests. State and local governments are sourcing these materials through city capital delivery departments, county transportation authorities, and university procurement offices issuing RFPs and IFBs for construction contracts. The issuing bodies in recent solicitations include city departments managing bond-funded capital projects, county transportation authorities, and higher-education institutions procuring materials for operational and construction needs.

Recent activity clusters in Texas and Wisconsin. The City of San Antonio Capital Delivery Department posted two major construction RFPs in June and July 2026 for the Hays Street Bridge Connections & Eastside Area Streets project (due August 25, 2026) and Fire Station #33 Facility Replacement (due July 30, 2026), both 2022 Bond-funded projects that reference structural components including concrete beams, concrete piles, and structural shapes. Sarasota County in Florida solicited an IFB for the Midnight Pass Road Pedestrian Bridge (due July 20, 2026) specifying a steel truss deck, prestressed concrete piles, concrete end bents, and approach slabs. The University of Wisconsin-Madison issued an RFB for general metals procurement—steel, aluminum, and stainless steel (due April 20, 2026)—indicating material sourcing for institutional operational needs. The code shows moderate activity across municipal and county infrastructure improvement programs, with some supply-side procurement by educational institutions.
