UNSPSC 31321309: Stainless steel riveted bar stock assemblies

UNSPSC 31321309 Stainless steel riveted bar stock assemblies is a Commodity code that encompasses sheet metal, metal plate stock, and fastening hardware components used by state and local agencies for operational needs, maintenance, and construction support. Recent state and local solicitations under this code show procurement of stainless steel diaphragm plates, temperature sensors with mounting hardware, anchor bolts, drive caps, post base plates, and sheet metal and metal plate raw materials. The issuing bodies span higher-education systems, state environmental and criminal justice agencies, municipal departments of public works and transportation, and specialized state commissions. The work typically involves supply of raw or finished metal materials and hardware to support in-house operations—sign shops, water treatment facilities, utility operations, and maintenance divisions—rather than project-specific fabrication or assembly work.

Recent activity concentrates in Texas, Michigan, Illinois, and Georgia. The Texas A&M University System issued an ITB for stainless steel diaphragm plates due October 28, 2026, through the AggieBid procurement portal. The City of Detroit Office of Contracting and Procurement solicited anchor bolts, post base plates, and drive caps for its Traffic Engineering Division Sign Shop through RFQ 547916, due August 12, 2026, with a mandatory Detroit-based business certification requirement and a three-year contract term. The State of Illinois posted a Blanket Order Agreement for stainless steel angle and square tube with proposals due September 11, 2026, enabling flexible as-needed purchasing. The Texas Department of Criminal Justice requested bids for sheet metal and metal plate raw materials under IFB IW258604, due July 28, 2026. The Texas Water Development Board issued an IFB for temperature sensors, cables, and mounting equipment with exact brand and model specifications due August 25, 2026. These recent opportunities reflect routine material supply and inventory replenishment for state and local operational assets rather than large capital infrastructure projects.
