Arrow Vinyl Murryhill 12 x 17 storage 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 Murryhill steel building can provide the solution for substantial storage needs or workshop/hobby spaces. The unique roll-up, garage-style door provides easy access and stores the doors out of the way. The gable roof blends attractively with the building's durable vinyl-coated exterior steel finish to give you maximum value for your storage dollar and a second sliding side door allows convenient, additional access.
