NIGP 28578: Structural Supports and Racks, Mechanical Type: Angles, Braces, Brackets, Channels, Clips, Fittings, Spring-Nuts, etc.

NIGP 28578 Structural Supports and Racks, Mechanical Type (Item) encompasses angles, braces, brackets, channels, clips, fittings, and spring-nuts that state and local governments procure as components for infrastructure, fleet, and facility systems. Recent solicitations show demand for structural and mechanical fastening elements embedded in larger rail, electrical, power distribution, and construction projects. Charlotte Area Transit System sought S70 light rail vehicle conical spring spare parts to support operations; the City of College Park Power Department solicited decorative lighting poles, crossarms, and related structural materials for electrical distribution; and the Florida Department of Agriculture and Consumer Services requested steel structures for a 115 kilovolt substation, including deadend line terminals, bus supports, and breaker disconnect switch supports. Issuing bodies span transit authorities, municipal utilities and power departments, state agencies, and school districts. The code draws activity from engineering-heavy operations that require structural components as line items within broader infrastructure, maintenance, and construction contracts.

Geographic activity concentrates in the Southeast and Texas, with recent opportunities posted from Charlotte, North Carolina (transit); College Park and Athens, Georgia (municipal power and school district); Long Beach, Mississippi (harbor construction); and Florida (state substation work). The mix reflects mid-size to large jurisdictions with capital-intensive electrical, transportation, and facility infrastructure. Representative recent solicitations include Charlotte Area Transit System's RFQ for S70 LRV conical spring inventory spare parts (response due November 2, 2026), the City of College Park Power Department's ITB for power distribution materials including 75 fiberglass dead-end crossarms and 60 decorative lighting poles (bids due August 10, 2026), and the Florida Department of Agriculture and Consumer Services' IFB for 115 kilovolt substation steel structures comprising eight structural assemblies (proposals due July 21, 2026). These opportunities suggest steady demand for discrete structural components as consumables and replacements within public-sector infrastructure operations.
