About us.

We do doors… period.

Simply put, we specialize in manufacturing bi-fold doors. This means that we concentrate our efforts on designing the best bi-fold on the market. And we think you’ll agree. From our innovative locking systems, to our patented insulated style door, we continue finding new ways to make our product work better for you.

Diamond Doors is a family run business specializing in the production of bi-fold doors. Owner Dick Suderman, a commercial pilot and aerial applicator, began building custom bi-fold doors in the off season in the mid 1980’s for local shops and aviation hangars. By 1992, the demand for more and more doors prompted him to start manufacturing them on a full time basis. In 1998, Diamond Doors began operations as a full scale manufacturing facility in Southern Manitoba. With the help of his sons, the company has steadily grown to compete as an innovative industry leader.
