UNSPSC 31341609: Stainless steel bonded sheet assemblies

UNSPSC 31341609 Stainless steel bonded sheet assemblies (Commodity) encompasses flat metal stock and fabricated plate materials that state and local governments procure for water treatment infrastructure, traffic safety systems, and facility operations. Recent solicitations under this code show a mix of raw sheet metal and plate stock purchases alongside finished metal components—including stainless steel angle and square tube stock, sheet metal plate materials, and precision-machined metal assemblies such as diaphragm plates, post base plates, and anchor fasteners. The issuing bodies are concentrated among state agencies, municipal departments, and educational institutions: the Texas A&M University System, City of Detroit Department of Public Works, State of Illinois, Texas Water Development Board, and Texas Department of Criminal Justice have all posted opportunities in the past three months. The scope reflects both procurement frameworks (blanket order agreements and master supply agreements) and direct purchase orders for specific fabricated or raw components needed for ongoing operations.

Activity is distributed across Texas, Illinois, and Michigan, with Texas showing the heaviest recent concentration. The Texas A&M University System posted an ITB for stainless steel diaphragm plates due October 28, 2026 (TAMUSITB270547), requiring electronic submission through AggieBid. The City of Detroit Office of Contracting and Procurement issued an RFQ for anchor bolts, post base plates, and drive caps due August 12, 2026 (RFQ 547916), with a mandatory Detroit-based business certification and a three-year contract term; the City reposted a rebid version of this solicitation in September 2026 after the initial close. The State of Illinois solicited proposals for a blanket order agreement covering stainless steel angle and square tube materials, due September 11, 2026, with standard liability insurance and recordkeeping requirements. The Texas Department of Criminal Justice issued an IFB for sheet metal and metal plate materials due July 28, 2026, posted on the Bonfire procurement portal. These solicitations indicate sustained procurement demand for both raw metal stock and finished metal assemblies across infrastructure, safety, and facility maintenance categories.
