Constructed to provide you with the maximum achievable opening, this ingenious system uses overhead sliding tracks mounted to the concrete ceiling or slab. This allows for individual aluminium door panels to hang and slide on the track and be individually stacked away out of view. This system is popular with restaurants and supermarkets, as it does not need tracks installed on the floor. In addition the versatility of the overhead tracks allows the doors to take corners to suit the specific design and layout as there are no hinges involved. Partial opening or closing of the stack away doors is easily achieved to suit your requirements.
