Zinc Aluminized Magnesium Steel Coil And Sheet (PPZAM)

PPZAM product introduction
The types of color steel substrate are galvanized substrate, aluminized zinc substrate, zinc aluminum magnesium substrate.

PPZAM is pre-coated with zinc-aluminum-magnesium and adopts zinc-aluminum-magnesium steel coil as the substrate.
Aluminized magnesium zinc steel plate is a new type of high corrosion resistance coated steel plate, the composition of the galvanized layer is mainly zinc, composed of zinc plus 11% aluminum, 3% magnesium and trace silicon, steel plate can be produced in the thickness range of 0.27mm-- 9.00mm, can be produced in the width range of: 580mm-- 1524mm.

Due to the compound effect of zinc, aluminum and magnesium, the corrosion inhibition effect is further improved. In addition, it has excellent processing performance under severe conditions (drawing, stamping, bending, painting, welding, etc.), high hardness of the coating and damage resistance. Compared with ordinary galvanized and aluminum-plated zinc products, less coating adhesion can achieve better corrosion resistance, because of this superior corrosion resistance, in some areas can be used instead of stainless steel or aluminum. The corrosion resistance and self-healing effect of the cut end part is a major feature of the product.
The products are mainly used in civil construction (keel ceiling, porous plate, cable bridge), agricultural livestock production (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 external body), automotive motors, industrial refrigeration (cooling tower, large outdoor industrial air conditioning) and other industries. The field of use is very wide.
The world's best quality aluminum-plated magnesium zinc plate is the SuperDyma, referred to as SD board, developed successfully by Nippon Steel mills in the early 20th century, and its full name should be aluminum-plated magnesium zinc (silicon) board. Silicon is a kind of promoting element, in accordance with the appropriate proportion of added, will make the aluminum plated zinc magnesium plate with a cross-section self-healing function, for example, due to the need for sizing, the length direction we need to cut the SD board, cut the broken steel plate without protective film, according to common sense will gradually with atmospheric oxygen, water electrolysis reaction to rust, but due to the fluidity of magnesium ions, It will flow to form a new protective film in the part of the fracture that is not covered by the protective film, which means that even if you use a hard tool to scratch or destroy the protective film on the surface of the steel plate, you do not need to worry about the self-healing of the incision in a short time will solve the problem.

1. The material difference between zinc aluminum magnesium plate and galvanized plate
Zinc aluminum magnesium plate refers to zinc, aluminum, magnesium as the main alloy elements of the coated steel plate, that is, the United States ASTM standard ZAM material. Galvanized sheet refers to the zinc coating by hot dipping or electroplating on the surface of the steel plate processing materials. The material difference between the two is that the main alloying elements of zinc-aluminum-magnesium plates are aluminum and magnesium, while zinc is only an auxiliary element. This makes the zinc-aluminum-magnesium plate have better corrosion resistance and strength.

2. Zinc aluminum magnesium plate and galvanized plate corrosion resistance difference
Because the main alloying elements in Zinc-aluminum-magnesium plate are aluminum and magnesium, it has higher corrosion resistance and quality stability. Zinc-aluminum-magnesium plate has excellent corrosion resistance, deformation and weldability, and can maintain the original appearance and performance after long-term use. The anti-corrosion effect of galvanized sheet is relatively weak, and it is easy to be locally corroded, especially in high temperature and humid environment.

3. Processing performance difference between zinc-aluminum-magnesium plate and galvanized plate
The processing performance and corrosion resistance of zinc-aluminum-magnesium plate are better than that of galvanized sheet, first of all, from the material itself, zinc-aluminum-magnesium plate is relatively hard, resistant to cutting, and does not produce rust spots and oxidation skin. In addition, in the process of stamping, die-casting, deep drawing, bending, stretching and other processing, the deformation and resilience of zinc aluminum magnesium plate are better, and it has more advantages in the manufacture of various products that need to be processed.

4. The difference between the use of zinc aluminum magnesium plate and galvanized plate
Zinc aluminum magnesium plate because of its better anti-corrosion and strength, can be used in building exterior walls, roof panels, home appliances, automobiles, transportation facilities and other fields. Galvanized sheet is widely used in the manufacture of metal construction, shipbuilding, rail transit, household appliances, electronics and other industries and fields.

【 Conclusion 】
In summary, the main difference between zinc-aluminum-magnesium plate and galvanized plate is the material, corrosion resistance, processing performance and use. Zinc-aluminum-magnesium plate has advantages in anticorrosion, strength and processability, and has a wider application field.
