Color coated steel is an organic coating applied to the steel surface, it has a beautiful appearance, high strength, good corrosion resistance, easy molding and other advantages. It also called organic coated sheet or pre-coated steel, which is a metal sheet (cold rolled plate, hot galvanized plate, aluminum plate, high aluminum plate, stainless steel, etc.) as the substrate, the surface coating or lamination of various organic paint or plastic film made. Because it is a complete coil surface coatings in metallurgical plants, for users directly processed into products, it is also known as pre-coated sheet.
Both advantages of both organic polymers and color-coated steel sheets, both excellent colored organic polymers, form ability, corrosion resistance, decorative, but also high-strength steel sheet and ease of processing, it can be easily punching, bending, deep drawing, welding and other processing. This makes organic coated steel products made with excellent practicality, decorative, work ability and durability.
Now color-coated variety, about more than 600 kinds, but it still not a unified classification, because it is difficult to find a criterion to distinguish between the many varieties, while each has its own unique equipment manufacturers, technology, product range variety.
As a general habit, it can be divided into the following five categories.
(1) By using a substrate classification; it used for organic coated steel substrate are: cold-rolled plate, hot galvanized plate, galvanized plate, alloy plate, galvanized aluminum, galvanized metal sheet, tin plate, chrome steel, aluminum and the like.
(2)By classification process; there are roller coating, spray coating, powder method, laminating, printing, etc by coating methods. The resulting organic coated steel. By coating different times, there is a coat by a baking, two coat by two bake, three coat by three bake, four smear by four bake. The different processes baking coating obtained organic coated steel. Pressed flower or printing process point: can be subdivided into wood panels, marble, raised sticks, cement mortar lines and other coated steel.
(3)Classification by coating species; it usually classified according to the coating for the production of organic coatings, polyvinyl chloride coated steel, polyester coated steel, acrylic-coated steel, fluorocarbon coated steel, silicone-coated polyester steel and so on.
(4)Classification according to coating properties; according to organic coatings Features points, there are high weathering coating plate, high temperature coating plate, self-extinguishing coated plate, sterilization coated plates, non-stick coating plate snow resistant fingerprint coating panels and self-lubricating coatings board.
(5)By special coatings and use classification; such as epoxy zinc-rich paint, cold-rolled steel as a substrate of organic coated steel, with a surface coated steel sheet as well as some special machine coating clad sheet, such as Tamerlane diaphragm , sandwich panels, shockproof board.
