Arrow Vinyl Dallas 10 x 12 standard shed. Its frame, wall and roof parts are made from vinyl-coated, electro-galvanized steel, which is five times thicker than uncoated, electro-galvanized steel. All painted parts have a double baked-on enamel paint finish that will keep your building serviceable and attractive for years. The Arrow vinyl Dallas steel shed with horizontal siding gives you a durable storage solution. Its tall and gable roof allows for plenty of headroom with space to work, hang tools and store equipment.
