The design of this rustic shelving or bookcase unit is a heavy industrial aesthetic. It's a beautiful addition to any home or business that wants a touch of modern industrial. The size of the shelving is 6 feet high, 7 feet long, and 12 inches deep. The shelves are made of maple plywood sealed with a heavy coat of durable polyurethane. The steel rebar is coated with a special type of lacquer that prevents the steel from rusting but doesn't add a sheen to keep the steel patina raw and unfinished in appearance.
