Bare steel structures — A new concept

Certain high-strength low-alloy steels form a self-protecting oxide film that permits their exposure to the atmosphere in the bare or uncoated condition. These steels are finding applications ranging from transmission towers to distribution transformers on electric power systems. A detailed discussion is presented of how one of these steels can be used to advantage for outside structures, particularly in those areas where maintenance costs of galvanized and painted structures are high
