I have a project that involves substantially shortening solid exterior

that amount from the bottom of the door and still retain integrity?
These doors are to be used as bi folds.

As a reminder to some of the folks, there are 2.54 centimeters
per inch. So there are 25.4 millimeters per inch. So it's easy
enough to figure that 75 millimeters would be 3 inches, with
the remaining 15 mm another 3/5 of an inch.
