UNSPSC 40141904: Ferrous alloy ducts or ductwork

UNSPSC 40141904 Ferrous alloy ducts or ductwork is a Commodity code that covers ferrous-based duct materials and components, typically specified in building HVAC and fire-safety system installations and upgrades. Recent state and local solicitations show the code being used for replacement and retrofitting work on smoke control systems, fire dampers, damper position monitoring equipment, and associated ductwork in institutional facilities undergoing building automation system overhauls. County governments and special districts appear to be the primary issuing bodies under this code, with Orange County, Florida recently soliciting sealed bids for ductwork accessories at a corrections facility.

Orange County, Florida, posted sealed-bid opportunity Y26-718 on October 6, 2026 for Corrections Booking and Release Center smoke and fire alarm air duct accessories, with bids due October 20, 2026 and an estimated contract value of $2.89 million; the scope includes retrofitting fire and smoke dampers, terminal boxes, duct heaters, air handling units, and energy recovery units as part of a Johnson Controls Metasys building automation system installation, with a non-mandatory pre-bid meeting and site visit held on September 1, 2026, electronic submission required via OpenGov e-Procurement Platform, a 10% bid bond required, and a 5% Service Disabled Veteran-owned business preference available. The source shows limited recent activity; the other opportunities present in the data (boiler and chiller maintenance for a transit authority, construction manager at-risk services for a school district, and a cooperative law enforcement equipment procurement) fall outside the ferrous ductwork scope and suggest the code sees narrow, project-specific use rather than ongoing market demand.
