Industrial roller

Our GDN industrial roller shutter doors are manufactured from scratch and are integral to the security of any premises requiring a secure, robust, long lasting industrial door. Our roller shutters can be galvanised or powder coated to match the design integrity of your development. When open they allow free access and unobstructed space. All the doors are custom designed with your choice of accessories.

Customised

All doors are customised to suit your specific opening requirements. A variety of profiles such as solid standard slats 75mm wide, perforated slats 75mm wide and punched slats 75mm wide, using a steel thickness of 0.6mm, 0.8mm or 1mm thickness depending on the application of the door and size. We use a standard size guide 0f 75mm wide but also offer 100mm and 150mm wide guides for high wind areas and large doors reaching a width of 5.5meters wide and over. The door can be powder coated to match your development, also a combination of slats can be used to allow for a vision panel or purely for a unique aesthetically pleasing look. A variety of locks and operating mechanisms are available and will be discussed with you according to the application. We install the doors and will train the operators where necessary.

Operating Mechanisms

We offer 3 types of manual operation, a push pull, chain operation and a crank operation. We also offer electric driven motors both single phase and 3phase with the Marentec brand being the most popular.
