About Us

Our Story

Established in 1928 by Clarence Smith, Sr., Diamond Steel has evolved over the years under the leadership of President Dave Collins into a distinguished firm specializing in a wide range of services including steel erection, “in-plant” maintenance, crane and industrial equipment rentals, and industrial hauling. While our primary focus remains in Mahoning, Trumbull, and Columbiana counties in Ohio, Diamond Steel extends its expertise to Western PA, Northern West Virginia, and occasionally serves clients in Cleveland and Toledo.
