The compound effect of these added elements further inhibits the corrosion inhibition effect. In addition, it has excellent machining performance under harsh conditions (tensile stamping, bending, coating, welding, etc.), with high hardness and excellent damage resistance. Less plating allows better corrosion resistance than ordinary galvanized and aluminized zinc products. Due to this super corrosion resistance, stainless steel or aluminum can be replaced in some areas. Self-healing of cutting end is the main feature of the product.

At present, the world's best quality aluminized magnesium zinc plate is Nippon Steel's super steel SuperDyma, it is successfully developed in the early 20th century, referred to as SD board, its full name should be aluminum plated magnesium zinc (silicon) board. Silicon is an accelerant element. After adding appropriate proportion, the aluminized zinc-magnesium plate has the self-healing function of the end face. For example, we need to cut the SD board in the length direction due to the need of fixed length. After cutting, the ends of the plates do not protect the film. According to normal principle, oxygen and water in the atmosphere will be gradually electrolyzed. It is rusty, but due to the fluidity of magnesium ions, a new protective film will form on the uncovered part of the port. This means using a hard tool to scratch or break the protective film on the surface of the steel plate without worrying, and the shorter the cut, the shorter the problem will take.

At present, in addition to the import of the new Nippon Steel RIxin ZAM, Jisco SCS also came out. If you need to know more product differences and prices, welcome to consult.
