NIGP 57091: Tubing, Structural Grade

NIGP 57091 Tubing, Structural Grade is an Item code covering metal tubing and structural components used in fabrication and construction projects by state and local jurisdictions. State and local governments procure structural-grade tubing primarily for custom metal fabrication work—including protective infrastructure such as hand railings, anti-vandalism boxes and covers, steel cages, and security enclosures—as well as for repairs and modifications to facility assets. The work typically involves cutting, welding, finishing, and assembly performed either at vendor fabrication shops or on-site, with materials spanning steel, galvanized steel, stainless steel, and coated variants. Cities are the primary issuing bodies under this code, sourcing these materials and services through their facilities and maintenance departments to address both routine repairs and specialized protective projects driven by vandalism prevention and safety requirements.

The City of Tucson, Arizona posted RFP No. 240080 on March 26, 2026, soliciting steel fabrication services for its Facilities and Communications Maintenance department, with a proposal due date of November 30, 2023, at 2:00 P.M. local time. The procurement requires vendors to demonstrate capabilities in metal fabrication, machining, metal finishing, mobile welding, and emergency welding across multiple materials, with most work performed at the contractor's fabrication shop and a typical project completion timeline of six weeks. The contract includes a one-year initial term with options to extend for up to four additional one-year periods. Section 3 Program requirements mandate that 25% of total labor hours be performed by Section 3 Workers, with 5% specifically by Targeted Section 3 Workers, and compliance with disadvantaged business enterprise participation and Buy America provisions applies.
