About Roller Shutter Doors
Whatever the size or finish of the shutter curtain, power operated or manual operation, standard or fire-rated we can generally offer a guide price proposal by return.
Roller Shutter Doors consist essentially of a curtain of interlocking slats which form a continuous hinge along their entire length. This construction permits the curtain to roll up or down as it is raised or lowered onto a reel which is mounted on steel support brackets. A bottom rail fitted to the curtain strengthens the curtain and allows for the fitment of handles and locking devices.
The curtain is also prevented from moving side-ways by side channels or guides. The entire assembly is either bolted or welded to the structure and the rolling mechanism is enclosed in a canopy hood.
These doors are both economical and robust, which makes them one of the most popular types of industrial door on the market today. Each door is individually tailored to suit the customer’s requirements and can be manually or electrically operated.

In 2001 the directors decided to open a division that would manufacture, service and repair industrial doors. Our reliable service and quality workmanship has made us one of the leaders in this field to. We maintain a huge inventory of parts as well as direct factory support from a number of suppliers and manufacturers.
Materials that are used are as follows:
