Galvanized Steel Sheet is defined as a carbon steel sheet coated with zinc on both sides. Galvanized Steel Coil Importer produce galvanized steel with two main processes: continuous hot dip galvanizing and electrogalvanizing.
The hot dip process includes passing the steel through a molten zinc bath, and the electrogalvanizing process includes applying zinc through electrolytic treatment. As a result, the zinc layer is firmly adhered to the base metal through the iron-zinc bonding layer. Our hot-dip galvanized products are manufactured in accordance with specifications, and our electro-galvanized products comply with the specifications.
Galvanizing is one of the most effective and economical methods for protecting bare steel from corrosive environments. Zinc is not only a barrier between steel and the environment, but also sacrifices itself to protect the steel plate below. When two different metals are in contact and coupled with water and oxygen, sacrifice or current protection occurs. Zinc preferentially corrodes iron in steel. This protection prevents corrosion of the steel in areas not covered by zinc. Therefore, the diffusion of corrosion from cutting edges, drilling holes, etc. is minimized.

Many people know what galvanized steel is. It is used for a variety of applications from HVAC piping systems to garden barrels. Home decorations to the trash. The shiny finish on the surface makes it visually appealing, but it is also more durable and corrosion resistant.So, how is galvanized steel made? Where did the sequins come from? Let's find out.
Galvanized steel is carbon steel coated with zinc. The most common galvanizing method is the hot-dip process. The hot dip process involves immersing carbon steel in a molten zinc bath (approximately 680 degrees Fahrenheit). When the material is removed from the zinc bath and cooled, it reacts with oxygen in the air. This reaction causes zinc to become part of the steel (iron-zinc alloy bond). The new surface finish seems to have a crystalline finish or a bright finish.
Although this is the most common form of galvanizing, because the thickness of the final product is not easy to control, it is usually used for previously manufactured steel. Another method of galvanizing process is continuous galvanizing.
After continuous galvanizing passes through the zinc bath, galvanizing will be performed on the surface of the continuous steel strip (coil). The coil runs at about 600 feet per minute. When the coil leaves the zinc bath, it takes away an extra layer of molten zinc. Use high-pressure air (air knife) to remove excess zinc to form the desired thickness. The material is then allowed to cool and form a shiny finish. Skip galvanized steel sheet and continuous galvanizing can control the thickness more accurately, and is usually used for steel that has not been manufactured. As the thickness of the coating increases, the risk of losing some of the coating during manufacturing or forming increases.
Hot Dipped Galvanized Steel Sheets and sheets are produced for applications where corrosion resistance is important. Zinc coating extends the life of the final product and is ideal for manufacturers. The attractive surface finish also makes consumers satisfied.
