Arrow Vinyl Milford 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 Milford steel shed's attractive, horizontal siding provides a handsome storage solution for your yard. Its tall, gable roof allows for plenty of headroom with space to work within, or to hang tools and store equipment.
