For many buyers and distributors in the piping industry, the terms galvanized cast iron fittings and malleable iron fittings often raise questions. In reality, they refer to the same category of products—more precisely known as galvanized malleable cast iron fittings.

Material and Manufacturing Insights
- Galvanized Surface Treatment
These fittings undergo a hot-dip galvanizing process, which provides a strong layer of corrosion resistance. This makes them highly durable in plumbing, gas, and industrial pipeline systems.
- Malleable Iron Material
The core material is malleable iron, known for its toughness and ductility compared with traditional brittle cast iron. This ensures fittings can withstand mechanical stress during installation and long-term use.
- Cast Iron Manufacturing Process
The term “cast iron” reflects the production process—iron is cast into the desired shapes before further heat treatment and galvanizing.
Why the Different Terms?
Whether you see galvanized cast iron fittings or malleable iron fittings in catalogs, specifications, or purchase orders, both terms point to the same product. The variation mainly comes from differences in industry terminology and buyer familiarity.
