18' Wide x 21' Long x 10' High Carport with our top-of-the line, A-Frame Vertical Roof System. The corrugated ridges in the roof panels are aligned vertically, or up and down, allowing water, snow, pollen, and leaves, to wash off the unit easily. The unit has a 3' wide panel on each side wall and each end is open for maximum clearance. This metal carport shelter will accommodate two compact cars or a small RV, as shown. See the Specs Tab for more details.
