A Journey of Innovation that began in 1946.

Ternes Steel Company

Dunbarton Door and Entry Systems began its innovative journey over sixty years ago in post-World War II Detroit, Michigan. William A. Ternes established Ternes Steel Company, Dunbarton’s founding company, in 1946 to develop military housing.

Slimfold® Steel Bifold Doors

In 1954 the company began production on the first steel bifold closet door, based on an original design. With the introduction of the Slimfold® door, the small company entered the building products industry — and never looked back.

Location to Dothan, Alabama
In 1972 the company moved to Dothan, Alabama. The move was assisted by key personnel who had seen the company grow into a major U.S. producer of steel closet doors. The location was more convenient for the emerging Southeast and Caribbean markets, and provided excellent transportation and climate advantages. Dunbarton added a new product to its manufacturing processes: the Rediframe® Prefinish Steel Door Frame.

Dunbarton Today
Today, Dunbarton manufactures three building product lines: Rediframe®Prefinished Door Frames, Slimfold® Closet Systems, and Achiever® Entry Systems. Production is located in Dothan, Alabama, and is supported by a nationwide network of distributors and a satellite facility in Camden, Tennessee.
