Diamond Roll-Up Door Inc. began manufacturing doors for the transportation industry in Upper Sandusky, Ohio in 1991. In January 1996 Diamond Roll-Up Door was acquired by AM Group and this led to the introduction of a wide range of aluminum roll-up door products to the US market.
In January 2005 AM Group acquired Dover Roller Shutters Ltd in England, UK. Dover was the original manufacturer of aluminum roll-up doors for use on fire apparatus. A significant proportion of Dover Roller Shutter products were manufactured in England and supplied into the US and Canada to fire departments throughout both countries.
In 2007 Diamond Roll-Up Door began manufacturing and marketing the Dover Roller Shutters products in the US. This ensured high quality product, fast lead times for new doors and spare parts, and an improved ability to communicate and meet the needs of US customers. One of our most popular products, the Nyloy 30 door, is now made in the US to the same exacting standards that made it so popular here in the US. The Nyloy 30 is a heavy duty premium aluminum roll-up door.
All Diamond Roll-Up Door aluminum and architectural roll-up door products are now made under the Dover Roller Shutters banner.
Today Dover Roller Shutters is a designer and manufacturer of custom engineered door products for the following markets:
