Charter Dura-Bar

What Charter Dura-Bar does

Charter Casting, operating under the Charter Dura-Bar identity, is a U.S.-based industrial manufacturer founded in 1946 and headquartered in Mequon, with 251-500 employees. The company produces DuraBar® continuous cast iron bar stock and large complex iron castings (200 to 2,000 pounds), serving primarily industrial manufacturers and secondarily machining shops through a horizontal segmentation approach. It combines advanced molding capacity with disciplined process control to deliver uniform microstructure, tight tolerances, and structural performance in high-demand applications.

The underlying technology centers on proprietary continuous casting of iron bar stock, which yields uniform microstructure and exceptional machinability relative to steel, conventional castings, and aluminum. Complementing the core products, DuraBar Metal Services delivers value-added precision processing — cutting, drilling, turning, milling, and trepanning — that converts raw bar stock into ready-to-machine components, reducing customer handling and lead times. Large complex iron castings extend the portfolio into heavy structural applications with tight-tolerance requirements.

Charter Casting operates a B2B direct sales model with consultative engineering engagement (e.g., "Talk With Our Engineers"), targeting enterprise industrial buyers via field sales and industry-event participation (including Metalcasting Congress 2026). Pricing is quote-based and dependent on specifications, volume, and service requirements, with revenue generated through one-time product sales for bar stock and castings and per-operation/project pricing for Metal Services. No public pricing, customer logos, or revenue figures are disclosed.
