UNSPSC 11172000: Aluminum based alloys

Aluminium-based alloys have aluminium as their main metal contained

UNSPSC 11172000 Aluminum based alloys (Class) encompasses raw and semi-finished aluminum materials that state and local agencies source for operational and production purposes. Recent opportunities under this code reveal a narrow but concrete scope: coiled aluminum stock for high-volume manufacturing, and welding consumables and repairs on heavy equipment. The Colorado Department of Corrections has solicited multiple awards of coiled 3105H21 aluminum alloy in 21-gauge thickness for license plate production at its Tag Plant in Canon City, specifying precise metallurgical properties (ultimate tensile strength 17,500–20,500 PSI, minimum yield strength 13,000–18,000 PSI, 16% elongation), Bonderite pretreatment, and conversion coating per ASTM B-449-Class 2. Hillsborough County, Florida, has also posted an ITB for mobile welding and fabrication services ($207,429.10 estimated value over three years) covering on-site repairs and minor fabrication on roll-off containers, loaders, backhoes, excavators, and stationary cranes at its Solid Waste Management Department South County Facility locations, with pricing structured around journeyman and apprentice labor, steel plates, channels, angle iron, tubing, and related consumables. The issuing bodies are split between a state correctional department with recurring procurement volumes and a county solid waste management operation with periodic service demand.

Activity concentrates in Colorado and Florida. The Colorado Department of Corrections issued at least three separate IFBs and one follow-on bid request between May and August 2026 for coiled aluminum to supply continuous production runs (ranging from 21,000 to 350,000 pounds per solicitation), with monthly delivery schedules to Canon City and FOB Destination, freight prepaid. Bids were due May 18 and May 23, 2026, with May 22 and May 26 public bid openings specified and award announcements anticipated by May 27, 2026. Hillsborough County's welding services ITB 2600389 closed September 16, 2026, with a four-hour response time requirement for standard business hours and 24-hour emergency repair completion. Service Disabled Veteran-Owned Small Business (SDVOSB) firms received a 5% preference on Colorado pricing. The code shows limited and specialized activity — suppliers compete on material specifications and delivery compliance in a small set of repeat buyers rather than across a broad municipal or school district base.
