UNSPSC 31361609: Stainless steel sonic welded plate assemblies

UNSPSC 31361609 Stainless steel sonic welded plate assemblies is a Commodity code that reflects state and local procurement of raw stainless steel materials, sheet metal, and plate stock for facility operations and construction projects. Recent solicitations show state and local buyers using this code primarily for raw material procurement tied to maintenance, manufacturing, and infrastructure work rather than finished sonic-welded assemblies; the Texas Department of Criminal Justice has posted multiple IFBs under this code seeking stainless steel sheets conforming to ASTM A240 specifications (14 gauge, Type 304L, 4' x 8' dimensions), along with broader raw metal materials and sheet metal categories. State agencies dominate activity, with the Texas Department of Criminal Justice appearing as a repeat issuer across multiple recent opportunities, supplemented by broader state-level raw materials procurement from the Texas Workforce Commission and Texas Department of Transportation. The code appears to capture commodity-level input materials for state operations and facilities maintenance rather than specialized fabrication services.

Texas dominates recent activity under this code. The Texas Department of Criminal Justice issued IFB IW240459 for stainless steel sheet, 14 gauge, Type 304L conforming to ASTM A240 (bid opening January 29, 2026), with two amendments clarifying dimensions and material type; more recently, TDCJ posted IFB IW258604 for raw materials—sheet metal and metal plate—with bids due July 28, 2026, through the Bonfire procurement portal. State-level procurement under this code appears episodic and driven by discrete operational needs rather than continuous demand. No recent opportunities show award values, volume commitments, or multi-year contracts in the available documentation. Bidders should monitor Texas procurement channels, particularly the TDCJ portal and the Electronic State Business Daily, for amendment activity and specification details; ESBD set-asides appear in some Texas solicitations under related codes, though specific set-aside language is not explicit in the stainless steel sheet opportunities reviewed.
