I have a 50x50 wooden truss type hangar with metal roof and sides but the two ends are open. I want to build hangar doors for the building myself and unless I do some major structural work, I really cant hang the doors from the structure. I am thinking to construct four panel doors that roll on tracks on the floor and guides at the top to keep the doors in place. I am thinking to use polyurethane or acetyl plastic wheels on the bottom of the four panels and have them roll in steel U-channel in the floor. Has anyone here done anything like this?
