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