NIGP 57091: Tubing, Structural Grade

NIGP 57091 Tubing, Structural Grade is an Item code covering the procurement of structural tubing used in construction, fabrication, and infrastructure projects across state and local jurisdictions. State and local governments buy structural tubing—typically carbon steel, stainless steel, or specialized alloys in round, square, rectangular, or other cross-sections—for bridge reinforcement, building frames, equipment supports, signage structures, and public works fabrication. The code draws bids from state departments of transportation, counties, cities, school districts managing capital projects, and special-purpose districts operating water, wastewater, and utility infrastructure. Purchasing vehicles range from individual competitive RFQs and ITBs for specific tonnage or dimensional specifications to cooperative purchasing agreements that bundle recurring tubing demand across multiple jurisdictions.

No recent state and local contract opportunities under this code appear in the current procurement record. Activity under structural tubing codes tends to concentrate in procurement cycles tied to capital budgets and infrastructure renewal timelines rather than continuous or frequent solicitation, and posting patterns vary significantly by jurisdiction and fiscal year.
