Sinowell Metal: A Leading Producer of Hot Dipped Galvanized Steel Coils

As a respected supplier of steel rolls and coils, we ensurehigh standards of the final material. Galvanized steel is carbon steel that has been coated with protective zinc on each of its sides. Our hot dip process bathes the steel in a bath of molten zinc. This application of zinc via electrolytic disposition ensures that the zinc adheres soundly to our base metal. Industrial perfectionists looking to buy coil coated galvanized steels can find quality and multiplicity of use withSinowell hot-dipped galvanized steel coils.

Our hot dipped galvanized steel coils may be employed in multiple settings and by many types of industries, including the automotive, construction, and appliance manufacturing where rust-resistance is of utmost importance. Because non-corrosive hot dipped galvanized steel coils are less costly than stainless steel, many industries rely on their reliable use and more affordable cost. A tight zinc coating is among the most effective and economical methods for protecting bare steel from corrosion. Sinowell galvanized steel coils can be found in a multitude of products that range from washing machines, refrigerators, flashing, ductwork, car parts, drum containers, decking, HVAC systems, and much more. Our hot dipped galvanized steel products are used in applications designed for the residential, commercial, and industrial sectors.

Creating Galvanized Steel Coils

As a leading galvanized steel coil manufacturer, Sinowell Metal employs best industry practices in the creation of our products. Our loyal customers can rest assured that Sinowell Metal features exacting processes to produce our hot dipped galvanized steel coils. During the production process, our engineers place cold rolled steel coils through our uncoiler. The steel travels through an accumulator where it undergoes pretreatment.

During the pretreatment process, the steel is carefully leaned and its coating is converted. Afterward, the coils are quickly but thoroughly dried before they receive their priming coat. Our coils are hot dipped in molten zinc that is heated to approximately 460 degrees C. Next the zinc-layered coils are dried in a finishing oven before heading to a water quench process. Finally, they travel through our exit accumulator and then onward to a recoiler where they are produced into galvanized sheet metal rolls before being shipped to our customers around the world.
