UNSPSC 31361609: Stainless steel sonic welded plate assemblies

UNSPSC 31361609 Stainless steel sonic welded plate assemblies, a Commodity code, describes metal plate materials and fastening components that state and local governments buy for infrastructure, facility operations, and equipment support. Recent opportunities under this code show procurement of stainless steel diaphragm plates, anchor bolts, post base plates, drive caps, and raw sheet metal and metal plate stock. Issuing bodies soliciting under the code span state agencies, municipal departments, and public university systems. The Texas Department of Criminal Justice, Texas Water Development Board, Texas A&M University System, and City of Detroit Department of Public Works have posted activity in the past four months, alongside state-level blanket order agreements and multi-year supply contracts. Work solicited ranges from specific engineered components (diaphragm plates for particular applications, temperature sensor mounting hardware) to commodity-grade raw materials on framework agreements enabling flexible, as-needed procurement.

Geographic activity concentrates in Texas and Michigan, with the State of Illinois also active. Recent representative opportunities include the Texas A&M University System's ITB for stainless steel diaphragm plates due October 28, 2026, submitted via the AggieBid portal; the City of Detroit's RFQ for anchor bolts, post base plates, and drive caps (due August 12, 2026, requiring Detroit-based business certification and a three-year contract term with firm unit pricing); and the State of Illinois' blanket order agreement for stainless steel angle and square tube materials (proposals due September 11, 2026, under the State Prompt Payment Act and prevailing wage compliance where applicable). The Texas Department of Criminal Justice posted an IFB for sheet metal and metal plate materials on July 14, 2026 (due July 28). Opportunities are primarily IFB and RFQ notice types with response windows of one to four weeks. Set-asides and preferences vary by issuing body—Detroit requires local business certification, Illinois imposes a $15 minority contractor initiative fee on contracts of $1,000 or more, and some opportunities reference prevailing wage compliance or workforce composition mandates where federal or state funds apply.
