Insteel Industries Inc
One of the largest U.S. makers of steel wire reinforcing products for concrete, Insteel supplies the prestressed concrete strand and welded wire mesh that strengthen buildings, bridges, and concrete pipes for nonresidential construction. The company began in 1953 when Howard Woltz Jr. bought a concrete block plant in Mount Airy, North Carolina, and it jumped into wire in 1974 after a steel shortage threatened its own operations. Its name comes from combining "in" and "steel," a nod to the industry it serves.
