UNSPSC 31231110: Stainless steel machined bar stock

UNSPSC 31231110 Stainless steel machined bar stock, a Commodity code, covers stainless steel and related metal materials that state and local governments procure for infrastructure, operations, and maintenance. Recent solicitations show state and local buyers acquiring stainless steel diaphragm plates, angle and square tube stock, sheet metal, and metal plate materials to support facility operations, water treatment systems, and transportation infrastructure. The issuing bodies include state universities, state departments, city governments, and transit or utility agencies; Texas A&M University System, State of Illinois, Texas Department of Criminal Justice, Texas Water Development Board, and the City of Detroit have solicited under or near this code in the past two months. The work spans both commodity supply (framework agreements and blanket orders for raw materials) and application-specific components (diaphragm plates for machinery, base plates and bolts for traffic engineering operations).

Recent activity concentrates in Texas and Illinois. The Texas A&M University System posted an ITB for stainless steel diaphragm plates due October 28, 2026, via the AggieBid portal with questions directed to Sterling Crowdus at soprocurement@tamus.edu. The State of Illinois solicited a Blanket Order Agreement for stainless steel angle and square tube materials with proposals due September 11, 2026, requiring $1,000,000 per occurrence and $2,000,000 annual aggregate commercial liability insurance and $15 fee for minority contractor initiative vendors on contracts of $1,000 or more. The City of Detroit requested quotes for anchor bolts, post base plates, and drive caps for its Traffic Engineering Division Sign Shop, with the rebid due September 17, 2026; the earlier iteration due August 12, 2026, required Detroit Based Business Certification and a three-year contract term with 50 percent Detroit resident workforce composition. The Texas Department of Criminal Justice posted an IFB for sheet metal and metal plate materials due July 28, 2026. Code activity remains modest and draws primarily from operational supply needs rather than high-volume construction procurement.
