Iron Foundries

Overview

This U.S. industry comprises establishments primarily engaged in pouring molten pig iron or iron alloys into molds to manufacture castings (e.g., cast iron manhole covers, cast iron pipe, cast iron skillets). Establishments in this industry purchase iron made in other establishments.

The immediate parent of national industry 331511 is international industry 33151: Ferrous Metal Foundries
