UNSPSC 31350000: Fabricated tube assemblies

UNSPSC 31350000 Fabricated tube assemblies is a Family code that encompasses metal fabrication services and component manufacturing, including structural steel products, welding supplies, custom metal assemblies, and related fabrication work that state and local governments procure for infrastructure maintenance, equipment repair, facility operations, and specialized construction projects. State and local buyers—counties, cities, school districts, correctional facilities, water authorities, and transit agencies—use this code to source structural steel components, metal products for HVAC and welding applications, pipe assemblies, guard rail components, and custom fabricated metal items required for ongoing capital and maintenance operations.

The recent opportunities show sparse activity directly aligned with the code's scope. Of the reviewed opportunities, only a handful represent core fabricated-tube or structural-metal procurement: the Colorado Department of Corrections' metal shop sourcing (structural steel components, square tubes, angle pieces, sheet stock, and plates, Documented Quote due March 27, 2026); the Commonwealth of Kentucky's sheet metal and steel for welding, HVAC, and machining at area technology centers (Request for Bid with March 20, 2026 deadline across fourteen product categories); and the University of Wisconsin-Madison's metals procurement (steel, aluminum, stainless steel, with April 20, 2026 response deadline). Most other opportunities tagged under the code address unrelated scopes—MRO supplies, bridge rail components, guard rails, water filters, and telecommunications infrastructure—indicating inconsistent code application across jurisdictions. Geographic spread shows activity in Colorado, Kentucky, and Wisconsin, with scattered procurement from water districts and transportation authorities in California and Florida. The code shows limited recent-opportunity volume and modest concentration; pursue selectively based on capability in structural steel fabrication, welding-grade materials supply, and custom metal assembly for public works and facility operations.
