UNSPSC 31151615: Roller or plate top chain

A kind of chain comprised of inner and outer --or top-- plates that provide greater loading capacity and permit higher speed with a single power traction unit.

UNSPSC 31151615 Roller or plate top chain is a Commodity code that encompasses industrial and commercial chain products for municipal operational use, including transport-grade chain, alloy steel chain, galvanized proof coil chain, and specialty chain products with specified working load limits and material compositions. State and local governments procure these items as consumable inventory to support various departmental functions — maintenance, public works, law enforcement equipment, and facility operations — typically in modest quantities ordered on an as-needed basis with fast delivery requirements and fixed pricing. Issuing bodies include municipalities such as the City of Tampa, county governments, and state-backed cooperative purchasing entities like Sourcewell, which aggregates demand across multiple jurisdictions and participating public entities to establish framework contracts.

Recent activity concentrates in Florida and the Pacific Northwest, with the City of Tampa and Hillsborough County together responsible for at least two documented solicitations. The City of Tampa issued RFQ 26-P-00328 for Chain for Inventory, posted May 12, 2026 with a June 15, 2026 submission deadline, seeking six line items including 800 feet of 3/8 inch transport grade 70 chain, multiple specifications of proof coil galvanized chain, and alloy steel grade 100 chain with delivery required within five business days FOB Destination and payment terms at approximately 30 days. An earlier City of Tampa RFQ 26-P-00214 issued March 18, 2026 for Hooks and Shackles on behalf of Hillsborough County (due April 15, 2026) included roller chain components among 20 line items of lifting and securing hardware. Sourcewell's RFP #061626 for Law Enforcement Equipment, posted May 12, 2026 with a June 16, 2026 deadline, establishes a multi-jurisdictional cooperative contracting vehicle for law enforcement agencies across Washington, Minnesota, and other states, though the specific relationship between that broad law enforcement equipment code and roller chain products is unclear in the available documentation.
