Perhaps it is wise, when refurbishing a galvanized tower section that
shows some rust, to inspect the inside of any tubular member for rust or
other deterioration. Rust is a symptom of deteriorating galvanized
coating, which may, in some cases, occur inside a tube at a rate greater
than on the outside. If the galvanized coating fails on the inside,
painting the outside only may not make that tower section safe to use.
