Galvanized steel refers to that ordinary carbon construction steel is galvanized, which can effectively prevent corrosion and rust of steel, thereby prolonging the service life of steel. Among them, galvanizing is divided into electro-galvanizing and hot-dip galvanizing. Generally used in building exterior walls, such as glass curtain walls, marble curtain walls, aluminum curtain walls as columns and stress materials, or used in outdoor telecommunications towers, highways and other open-air construction steel called galvanized steel, of which galvanizing is divided into electro-galvanized and hot Dip galvanized.
