Galvanized square tubing undergoes a hot-dip process where the steel is coated in a layer of zinc. This coating isn't just paint; it creates a metallurgical bond that prevents oxygen and water from reaching the steel underneath. Even if the surface gets scratched, the surrounding zinc will sacrifice itself to protect the steel (a process known as cathodic protection). This coating isn't just paint; it creates a
