Home > Companies > HAG Ltd. - The Door Specialists > Industrial Door - Vertical Stacking Sectional Z Door

The Z Door is a vertically stacking sectional door for use in industrial premises. The folding design is patented to retract into a compact space above the door lintel so to avoid the requirement of the traditional running track and save the valuable high level space behind the door, allowing space for equipment such as vehicle lifts, cranes or lighting. The CFC free curtain is insulated and can be fully panoramic to allow maximum vision whilst retaining its security and its thermal values.


The Z door is used in applications where a compact industrial door system is required allowing space to be used behind the door at high level. The full panoramic system gives an attractive frontage for commercial and industrial premises such as vehicle workshops, garages, MOT stations, fire stations and distribution warehouses.
