C.H.I. continues to make advancements to the Commercial Garage Doors product line. The new C.H.I. super-imposed rolling steel door is actually two doors sharing a single pair of head plates and wall angles. The door is designed for applications that require maximum security and an environmental barrier some of the time and allow air flow and security at other times. Some typical super-imposed doors are a service door and grille or an insulated door and a service door with a perforated curtain, which allows air flow and provides an insect barrier. A number of different door and grille combinations are possible. These super-imposed door designs are preferred in many commercial, industrial, defense, and food service applications.
