I can't speak to the best type of graphic materials, but can give a little insight on their ability to bear weight. These vertical bifold doors are very stout. They have to be able to operate in high winds, which can impose some huge loads due to their large surface area. I've ridden a couple of different 60-foot wide hangar doors up by standing on the bottom rail. Not an OSHA-approved activity so don't try this at home kids, but the doors and their lift mechanisms handled my 220 pounds with ease.
