It means that ordinary carbon building steel can effectively prevent corrosion and rust of steel after galvanizing, so as to prolong the service life of steel, including electro galvanizing and hot-dip galvanizing.

Generally used for building exterior walls, such as glass curtain wall, marble curtain wall and aluminum curtain wall as columns and stress-bearing materials, or for outdoor telecommunications towers, highways and other open-air buildings, steel is called galvanized steel, in which galvanizing is divided into electro galvanizing and hot-dip galvanizing.
