Iverson soon emerges as one of the great visionaries and mavericks in American industry.The company opens a second Vulcraft plant in Nebraska to meet increasing demand for steel joists. Based on the success of its first two plants, Vulcraft purchases M&S Steel Company of Fort Payne, Alabama in 1967, which becomes Vulcraft – Alabama, and builds its fourth steel joist plant in Grapeland, Texas the following year. Business booms, and Vulcraft’s growth has continued ever since.Nucor continued to expand into steel-adjacent businesses, welcoming C.H.I. Overhead Doors, Summit Utility Structures, Sovereign Steel Manufacturing and Elite Storage Solutions to the Nucor family.
