Megadoor

The first Megadoor vertical lifting fabric door was developed in 1973 as a kiln door for the forestry industry, where extra-large doors with good insulation were especially needed. In 2012 Cardo, the parent company of both Megadoor and Crawford was acquired by ASSA ABLOY Group.

Construction costs by permitting a virtually unlimited opening width with variable height. The unique, robust design and structure offer high operational reliability and energy efficiency. Since the multiple-leaf aviation hangar doors lift vertically, the need for expensive ground tracks and door pockets is eliminated, enabling more cost-effective facility design. All the doors are available with translucent fabric for natural lighting, which improves both the working environment and allows for energy savings, since you are able to turn off part of your lighting during the daytime hours.

Multiple-leaf aviation doors allow for a flexible door opening and make it possible to accommodate multiple aircraft of different sizes in one hangar. For movement of ground equipment, you may open just one door leaf to a minimal height, which minimizes the loss of conditioned air.

Working with ASSA ABLOY Entrance Systems puts your facility in the hands of skilled and experienced engineers who are ready to support you through the entire operating life of your hangar doors. Receive the highest-class expertise – from site analysis and engineering specifications to installation, commissioning, service and support.
