Since 1928, Diamond Steel has been the Valley's first choice for steel erection, in-plant maintenance support, specialized industrial hauling and rental services. Serving Northeast Ohio and Western PA, Diamond Steel has the qualified people with the right equipment to handle your job properly. Due to a recent change in rules by the Ohio department of transportation, there has been an increase in Ohio permit fees.

Unfortunately due to the large increase in cost, these costs must be passed on. Have any questions or want to rent from us, please visit our contact us page to learn how.
Services
Diamond Steel was founded in 1928 by Clarence Smith, Sr. Today, 70 years later, president Dave Collins leads a firm specializing in steel erection, "in-plant" maintenance, crane and industrial equipment rentals, and industrial hauling.
