United Doors

The world renowned continuous sheet curtain roller doors – Strong, quiet and reliable.

The advantages of a roller door over the traditional up-and-over are plain to see. They save space inside and outside the garage, are easy to install and are more secure. Our doors are popular with major builders and householders because of the consistent quality and superior design characteristics.

The Garage doors are available in two options. An easy to operate manual version or with the complete luxury of “touch-of-a-button” automatic operation. The doors are manufactured with galvanized steel profile curtain and come complete with a maintenance-free Plastisol coating running through steel guide rails on either side of the door.

The doors are safe, secure and help to reduce draughts in your garage – compared to the standard “up and over” doors. Another advantage of this is that the doors roll up vertically and will not swing outwards into your driveway, meaning you can park right up against the door as well as saving space within the garage.
