Ours don't. The metal siding on our buildings is 29-gauge Galvalume-coated steel, a finish designed to go the life of the building without rusting or needing paint. That is a different material class from the thin bare-steel panels on big-box kit sheds, which can start corroding at the cut edges within a few seasons.
Under the steel is the same full wood frame and inner plywood paneling as every building we sell, so the metal is a skin, not the structure. If a panel ever takes damage from an impact, it can be replaced without touching the frame.
