A heavy, durable iron material cast into pipes and fittings used for plumbing drain systems.
Cast iron is an iron alloy with high carbon content that is cast in molds to produce pipes, fittings, and architectural elements. In construction, cast iron pipe is used for drain, waste, and vent plumbing systems where its weight and sound-dampening properties are valued. Cast iron is durable and corrosion-resistant but brittle and heavier than alternatives like PVC.
