Obviously, the impact of gases and liquids devastating effect on the metal, so there are methods of metal fencing from such exposure. All methods of protecting steel structures based on the principle obstruction of access of gases and liquids to the metal. One method of protecting steel is galvanized. Method of galvanizing is more reliable and practical than conventional paint. Ebay helps readers to explore varied viewpoints. Zinc applied in different ways. Hot-dip galvanized metal structure covered dense zinc cladding. After careful processing metal structure immersed in a container of hot zinc. This method of protection for several decades.
To a cold galvanizing resort when you can not hot. Steel structures can be so huge, that does not fit in any bathroom. Cold galvanizing – a drawing on metal structure of liquid zinc. Other types of galvanizing electroplating and diffusion, are rarely used, because they are specific. Zinc protects against corrosion better than enamelling. Galvanizing steel lengthens life is much better than paint. E malirovanie – another way to protect the metal, a cheap and simple. The paint layer is sufficiently dense to protect the metalwork.
A thin layer of enamel covers metal construction and does not develop corrosive reactions. The main drawback of this method – its short. Brown paint covers the metal layer, such coating is not durable. Direct sunlight adversely affect the paint layer. Paint dry up and crack and then fall off. In addition, the metal is not protected from mechanical impact on him. Any serious blow to the enameled steel deprives it of protection. Due to the fact that environmental factors are constantly affect the metal, and if not for modern methods to protect it, its life was less.
