UNSPSC 31121705: Iron centrifugal machined castings

UNSPSC 31121705 Iron centrifugal machined castings is a Commodity code covering the supply of cast-iron utility infrastructure components that state and local governments procure for water, sewer, and stormwater systems. The work under this code centers on manhole castings, frames, covers, and related accessories — standardized products manufactured through centrifugal casting processes and delivered to municipalities for integration into underground utility networks. Issuing bodies are typically counties and municipal utilities managing water and wastewater infrastructure; school districts and special-purpose districts solicit the code less frequently but purchase similar components for campus utility systems.

DeKalb County, Georgia posted an IFB on April 1, 2026 for manhole castings and accessories under a three-year multiyear contract with a response deadline of April 30, 2026 (Solicitation Number PE64400NONST2026000000240). The source provides no additional opportunities under this code, no geographic concentration data across states, and no information about set-asides, incumbent vendors, or award values. Vendors should monitor the DeKalb County procurement portal for the complete solicitation, detailed specifications, and any clarifications issued through addenda.
