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 onto 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.
