Galvanized pipe, also known as galvanized steel, hot galvanized and galvanized two electricity, hot dip galvanized galvanized thickness, with a uniform coating, strong adhesion, long life and other advantages. Electro galvanized low cost, surface is not very smooth, its own corrosion resistance than galvanized pipe worse. Angle may require different structures composed of a variety of different force components, but also for connections between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, material handling equipment, marine, industrial furnace, reaction tower, container racks, cable channel bracket, power piping, bus bracket, as well as warehouse shelves. Angle the case constructed of carbon steel, the steel is simple section steel, mainly used in the framework of metal components and factories and so on. In use, it requires a good weldability, plastic deformation and certain mechanical strength. Production of raw steel angle square billets of carbon steel billets, hot-rolled finished forming angle, normalizing or hot-rolled delivery.
