Hot-galvanized rolled metal

Demand for metal products is growing every year due to the increased pace of construction. Metal-roll, as one of the essential components of various structures and facilities used for building ships, factories, stadiums, and various engineering structures, widely used in the bridge and engineering, the oil industry. Almost all industries in varying degrees, used metal products. Properly selected, it is a guarantee promising designs for further exploitation of which are important quality and reliability of the metal. Rolled metal products for industrial produce processing metal pressure and high temperature. Thus, he acquires the desired shape, size and other desired properties. Processing of metal occurs on the rolling mills, out of which face various kinds of these products: rails, angles, beams, channels and so on. To obtain the metal-non-standard forms used by forging, stamping (on presses and hammers), drawing, pressing. Drawing on the surface of rolled thin layer of zinc is called galvanizing. For what it's doing? Active metal, zinc is oxidized and can not be formed on the metal surface rust (iron dioxide). Hot-dip galvanized steel (both one-and two-sided) in two ways: dipped in molten zinc parts or cause a zinc melt on the steel sheet during rolling. So produce hot-galvanized rolled metal. Coating of zinc is not only resistant to corrosion, but also for possible future processing. Galvanized coating, which is obtained by dipping steel in a bath containing molten zinc, is a series of layers of zinc alloy and base metal (galvanic) and contains up to 10% iron. If you use sverhnizkouglerodistye steel, this alloy gets a good ductility. By implementing a continuous process of galvanizing metal, seeking cheap this way. Thus, hot-galvanized rolled units to produce a continuous hot-dip galvanizing (in rolls and sheets). It is designed for painting, for the production of extruded packaging, parts, and various metal products, as well as for cold forming. Hot-galvanized metal products are widely used in various areas, especially in construction and engineering and automotive industries, such as rent is cheap, has a high resistance to corrosion and a wide range of products. For hot-dip galvanized metal is important to ensure debugging process to sustain high quality zinc coating. Recently, more and more galvanized metal additionally covered with plastics (usually paint). While in Western countries, this technology has long been put into practice, for a Russian producer hot-rolled until it is a novelty. In our country most of the hot-metal-producing plants such giants as Severstal, Magnitogorsk and Novolipetsk Steel. More and more experts have noted that the Russian metal products, including hot-galvanized, growing steadily in all quality indicators, becoming more reliable. The most popular sections and sheet metal, which is most often used in construction, especially in monolithic.
