Roller Shutters

Roller Shutter Doors
Harlech roller-gard shutter doors are suitable for various commercial and industrial applications including factories, warehouses, loading bays or wherever secure closures are required. The Laths interlock horizontally to form a rigid curtain to close the opening completely. When the shutter is coiled up in the open position, they leave a fully unobstructed opening.

The roller-gard shutters can be finished in plastisol, powder coated to BS or RAL colours or have a standard galvanised finish. Depending on the size of the door, they can be operated by push up, manual chain or electrically operated
