An industry first developed by Superior Doors; our steel doors are designed for applications where the highest rigidity in a door is required.
These doors primary use is in cavity sliders and other sliding applications where space is tight and doors must stay very straight to avoid scrapping or jamming.
There also perfect for locations such as between and internal garage and living space where the temperature and humidity can be very different either side of the door.
