UNSPSC 31351500: Bolted tube assemblies

UNSPSC 31351500 Bolted tube assemblies, a Class code, does not align with the recent state and local procurement activity tagged under it. The City of Tucson's RFP No. 240080, posted March 26, 2026, seeks comprehensive steel fabrication services including custom doors, steel cages, anti-vandalism boxes and covers, hand railings, and custom protective steel works for city assets — a scope centered on general metal fabrication and welding rather than bolted tube assembly manufacture or assembly. The Tucson opportunity requires capabilities in metal fabrication, machining, metal finishing, mobile welding, and emergency welding across steel, galvanized steel, stainless steel, aluminum, and coated materials, with most work performed at the vendor's own fabrication shop and typical project completion in six weeks. The contract offers a one-year initial term with four optional one-year extensions.

The code shows limited recent state and local activity aligned with its nominal scope. The single recorded opportunity is from the City of Tucson (Facilities and Communications Maintenance department), an Arizona municipal buyer. The procurement includes Section 3 Program requirements (25% of labor hours from Section 3 Workers, 5% from Targeted Section 3 Workers), DBE participation expectations, Buy America compliance, and civil rights standards tied to federal housing assistance funding. A pre-submittal virtual meeting was held November 16, 2023, with proposals due November 30, 2023, at 2:00 P.M. Arizona time. The scope mismatch between the code's definition and the actual work solicited signals that this Class code may not be actively pursued for its intended product category in current state and local markets, or that Tucson's tagging reflects a broader steel fabrication classification rather than bolted tube assembly specificity.
