Welcome to Mill Supply, your number one source for quality parts at discount prices! We've been proud to serve our customers since 1944 when we started in a small shop in downtown Cleveland. Seventy-six years and two buildings later, we're still in the same area and our customers are still our number one priority. It is our goal to ship most orders the same day when ordered before 3pm EDT. Our specialties are parts for stepvans, medium duty trucks, motorhomes, snow plows, and rust repair panels.
