Fingerprint Resistant Aluminum-Galvanized Steel Coil

Plating composition	Corrosion resistance mechanism	Corrosion resistance
55% aluminum, 43.5%, zinc, 1.5% silicon and other trace elements	It combines the physical protection and high durability of Al and the electrochemical protection of Zn, as well as the addition of a variety of trace elements, and has excellent resistance to atmospheric corrosion	In a neutral environment, the corrosion resistance is 2-4 times that of galvanized sheet with the same coating thickness

Product Advantages

The dendrite spacing is small

 

The dendrite spacing is an important factor to measure the corrosion resistance life of aluminum-zinc plating products, and the smaller the dendrite spacing, the better the corrosion resistance of the coating. If the dendrite spacing of aluminum-zinc plating is greater than 20μm, the corrosion resistance of the product is poor.

Due to the advantages of the formula and the control of the coating thickness, the dendrite spacing is 10-15μm under the electron microstructure, and the corrosion resistance of the product is good.

The dendrite spacing of Shinmade aluminum-zinc sheet is 10-15μm.

Ideal plating structure

 

The coating structure of Shinmade aluminum-zinc plating is staggered skeleton, which has good compactness, which can prevent the intrusion of rain and corrosive media, and the corrosion resistance of the product is good. If the coating structure is bamboo-shaped, the coating is not dense enough, and the corrosion resistance of the product is poor.

The zinc flowers are fine and uniform

 

The stability of the crystallization determines the size and uniformity of the zinc flower, and the zinc flower is precisely controlled under the joint action of steel strip temperature, liquid zinc temperature, surface roughness, post-plating cooling, and special formulation of molten zinc liquid.

The diameter of the zinc flower of Shinmade aluminized zinc is controlled between 0.5-3mm, and the zinc flower is small and uniform, and the appearance effect is stable.

Aluminum-zinc sheet refers to the steel plate plating on the basis of zinc added aluminum (passivation protection), the general composition is 55% aluminum, 43.5% zinc, 1.5% silicon, with excellent atmospheric corrosion resistance, corrosion resistance is 2-4 times that of galvanized sheet, but also has the high temperature corrosion resistance of aluminum plate, smooth surface, good appearance.

Uses: building roofs, walls, electrical cabinets, home appliances, automobiles, color-coated substrates, etc.
