UNSPSC 40181800: Welded steel tubes

Tubes made of welded steel

UNSPSC 40181800 Welded steel tubes is a Class code covering pipe and tubular products for infrastructure and utility applications. State and local governments procure welded steel tubes primarily as components within broader construction and water resource projects, though the code shows limited recent direct solicitations. The code appears most relevant to water and stormwater infrastructure procurement, where counties and municipalities source pipe materials including reinforced concrete pipe, high-density polyethylene pipe, and corrugated metal pipe for distribution systems and drainage projects. Issuing bodies soliciting under this code span county departments of water resources, county transportation agencies, and county engineering divisions managing capital infrastructure projects.

Activity under the code concentrates in the Southeast and California. Gwinnett County Board of Commissioners (Georgia) issued ITB BL079-26 on April 16, 2026, due May 19, 2026, for stormwater pipe on an annual contract covering reinforced circular concrete pipe, HDPE pipe, and corrugated metal pipe with delivery within fourteen days of order; the County awarded a four-year initial term with optional renewal periods. Santa Clara County (California) posted ITB ITBRDAFY260694 on April 29, 2026, due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project, which included removal and replacement of inductive traffic loops and guardrail systems but primarily focused on asphalt overlay and concrete curb work rather than welded steel tubing. The Gwinnett opportunity represents the clearer fit to the code's scope; the Santa Clara solicitation shows cross-tagging that does not align closely with welded steel tube procurement.
