NIGP 40035: Castings, Gray Iron

NIGP 40035 Castings, Gray Iron is an Item code covering gray iron castings and related products that state and local governments source for utility and infrastructure applications. Based on recent solicitation activity, municipalities are purchasing manhole castings and accessories — standardized underground utility access components cast from gray iron that integrate with sewer, water, and stormwater systems. The work is straightforward procurement of manufactured goods rather than fabrication or custom metalworking services; vendors supply finished castings meeting dimensional and material specifications set by the purchasing jurisdiction.

DeKalb County, Georgia posted a three-year multiyear contract solicitation for manhole castings and accessories on April 1, 2026, with a response deadline of April 30, 2026, through its OpenGov procurement portal. The structure of this contract — multiyear, focused on essential utility components, and managed through a county procurement office — reflects how municipal water and wastewater departments use this code to secure steady supply of replacement and new-construction castings. Beyond the DeKalb County opportunity, the source provides no additional recent solicitations, geographic concentration data, or issuing-body patterns across other jurisdictions or states.
