Over 80 Years of Metal Fabrication Experience

Our corporate headquarters is located in Ohio at the convergence of two great rivers, the Maumee and the Auglaize, just across the river from the historic site of Fort Defiance. Built on the site of the old Turnbull Wagon Company, Defiance Metal Products has been in the business of producing quality metal parts for over 80 years.
