It includes removable zipper doors and three side panels that can be installed or detached at will to block wind, rain and sun, offering all-around protection for your belongings. The shelter features a rust-proof powder-coated steel frame (1.57"×1.57") paired with galvanized steel roof sheets for sturdy long-term use. Spacious enough to shelter cars, trucks and boats. It can also serve as a shaded area for parties and family get-togethers, or a covered work area for handcrafts. Each roof screw is fitted with a plastic gasket, together with waterproof adhesive tape to thoroughly prevent rain leakage. Made of 0.25mm galvanized steel sheets, the roof filters UV radiation, preventing your vehicles and outdoor gear from fading and aging under sunlight.
