Fast and reliable operation in tough environments.
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.
View brandMine door systems are designed to withstand dirt, corrosion, high-wind conditions and extreme temperatures. Robust and reliable, they offer long-term durability while ensuring top-safety and efficient access to your facilities. They also tolerate welding and grinding sparks or blast media overspray.
The flexible design means there are no practical limits to the size and configuration. A combination of translucent fabric in the upper part of the door and solid fabric at the bottom allows for maximum natural lighting, even in dirty environments.
