Galvanized ductile iron fittings are components used in piping systems, derived from ductile iron—an alloy known for its exceptional strength and flexibility. The term galvanized refers to the process of applying a protective zinc coating to inhibit corrosion. This combination yields fittings that are not only robust but also resistant to rust and deterioration, making them ideal for a wide range of applications, including plumbing, drainage, and heating systems.
