Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products.
CRC products are offered to the Automobile, Appliances, & Engineering sector as a premium raw material for transformation into any number of value-added products for the domestic and export markets.
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.
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.
Tin Mill Black Plate (TMBP) steel is manufactured from hot rolled coils by pickling to remove the surface oxide produced during the hot rolling stage, and cold reducing through a cold mill to the desired thickness. TMBP produces a low ductility product that is usually processed further to develop desired end use characteristics. These further reprocessing steps include annealing and temper rolling for formability and surface texture, and in some cases, tension leveling for flatness.
Black plate, once used primarily as a base metal for tinplate, has recently come to find wider application. Today it is not only used in tinplate and tin free steel, but also in cans, jewelry boxes, lipstick shells and dry battery jackets, which are competitive with tinplate and tin free steel counterparts, as well as in cold rolled coils for such diverse applications as building materials and automotive parts.
Tinfree Steel also known as Electrolytic Chromium Coated (ECCS) steel is a thin, cold rolled carbon steel sheet coated by electrolytic deposition with metallic chrome overlaid with a film of chrome oxide. Lower in price than tin plates, tin free steel boasts superior lacquer and paint adhesion and strong resistance against corrosion. Tin free steel is used in the production of cans, containers, electric equipments parts, home appliances and cables.
Tinfree Steel is largely used in the manufacture of Crown Caps, Lug Caps, Shoe Polish Tins and other non-food grade steel packaging containers. We buy and sell TFS material to serve the regular requirements of our customers.
Electrolytic Tinplate (ETP) is a thin, tin coated Cold rolled material. ETP material has worldwide acceptance as a recyclable material and is widely used for packaging of food, beverage and sanitary cans. The use of tinplate ensures that contents are free from bacterial and other external contaminations. Its shiny surface finish, superb corrosion resistance and formability make tin plates an ideal choice for the food industry and industrial parts producers. The special properties of tinplate and improved manufacturing technology is allowing for the utilization of tinplate in many new end products.
