Aluminized magnesium zinc steel plate is a new type of high corrosion resistance coated steel plate, the zinc layer composition is mainly zinc, composed of zinc plus 11% aluminum, 3% magnesium and trace silicon, the thickness range of the steel plate can be produced at present is 0.27mm- 9.00mm, the production width range is :580mm- 1524mm.
Due to the compound effect of these added elements, the corrosion inhibition effect is further improved. In addition, it has excellent machining performance under severe conditions (drawing, stamping, bending, painting, welding, etc.), high coating hardness and excellent damage resistance. Compared with ordinary galvanized and aluminized zinc products, less coating adhesion can achieve better corrosion resistance. Because of this super corrosion resistance, it can be used instead of stainless steel or aluminum in some fields. Cutting end part of the corrosion resistance of the self-healing effect is a major feature of the product.
Products are mainly used in civil construction (keel ceiling, porous plate, cable bridge), agricultural livestock (agricultural feeding greenhouses steel structure, steel structure accessories, greenhouse, feeding equipment), railway roads, power communication (transmission and distribution of high and low voltage switchgear, box type substation outside the body), automotive motors, industrial refrigeration (cooling tower, large outdoor industrial air conditioning) and other industries, It is used in a wide range of areas.
At present, the world's best quality aluminum-plated magnesium zinc plate is the SuperDyma, referred to as SD board, developed successfully by Nippon Steel Works in the early 20th century. Its full name should be aluminum-plated magnesium zinc (silicon) board. Silicon is a kind of accelerant element, in accordance with the appropriate proportion, will make aluminum plated magnesium plate with end face self-healing function, for example, due to the need of sizing, we need to cut the SD board in the length direction, after the cut steel plate end without protective film, according to the common sense will gradually occur electrolytic reaction with oxygen and water in the atmosphere to rust, but due to the fluidity of magnesium ions, This means that even if you use a hard cutting tool to scratch or destroy the protective film on the surface of the steel plate, you do not need to worry, the cut will heal itself in a short time to solve the problem.
