UNSPSC 30101503: Iron angles

UNSPSC 30101503 Iron angles, a Commodity code, covers structural steel components used in construction projects, particularly in bridge work and commercial building frames where angled steel members provide load-bearing or bracing support. State and local governments procure iron angles as part of larger construction projects through their capital delivery, transportation, and facility management departments. The work is embedded in competitive sealed proposals and invitation-for-bids processes for infrastructure and building construction, where angles are specified components within broader structural steel scopes. Issuing bodies include county transportation authorities, municipal capital delivery departments, and city public works offices managing capital-improvement bonds and major facility projects.

Recent activity centers on Texas and Florida infrastructure work. Sarasota County solicited steel truss pedestrian bridge construction (IFB 262861MN, due July 20, 2026) that specified structural shapes and steel members as core components of the project scope. The City of San Antonio Capital Delivery Department has posted two competitive sealed proposals: the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025, due August 25, 2026), which explicitly lists structural shapes among applicable NIGP categories, and Fire Station #33 Facility Replacement (RFCSP2026071, due July 30, 2026), which includes structural shapes as part of the new facility construction scope. Both San Antonio solicitations note pre-submittal conferences, mandatory site visits, and questions-due dates in mid-to-late July 2026, with awards likely to follow late summer 2026 completion of evaluation cycles.
