UNSPSC 30103508: Copper honeycomb core

UNSPSC 30103508 Copper honeycomb core is a Commodity code that describes specialized structural materials used in advanced composite construction, though recent state and local opportunities show limited direct procurement activity under this specific code. The three most recent opportunities posted—a pedestrian bridge construction in Sarasota County, Florida; street and greenway improvements in San Antonio; and a fire station facility replacement also in San Antonio—are primarily general construction solicitations that span multiple material categories including concrete, steel, structural shapes, and building systems, rather than copper honeycomb core materials specifically. State and local procurement under this code appears concentrated among municipal and county construction departments executing capital improvement and facility projects, with competitive sealed proposals and invitations for bids as the typical notice formats.

Geographic activity centers on Florida and Texas, based on recent postings. Sarasota County issued an IFB for the Midnight Pass Road Pedestrian Bridge (Solicitation 262861MN), due July 27, 2026, covering steel truss bridge construction with prestressed concrete piles and approach work. The City of San Antonio Capital Delivery Department posted two RFP-format solicitations in the second and third quarters of 2026: Hays Street Bridge Connections & Eastside Area Streets (RFCSP2026025, due August 25, 2026), encompassing linear creek greenway and roadway improvements across multiple eastside streets funded through the 2022 Bond; and Fire Station #33 Facility Replacement (RFCSP2026071, due July 30, 2026), a new-construction project at 2935 Castroville Road with a mandatory June 29, 2026 site visit. The copper honeycomb core code itself does not surface as a primary procurement driver in these opportunities, suggesting the code may represent a narrow material specification within broader construction scopes rather than a standalone purchasing category in state and local government.
