Fingerprint Resistant Aluminum-Galvanized Steel Coil

Product Advantages

Small dendrites space distance    

 

Dendrite spacing is an important factor in measuring the corrosion-resistance of the coated products. The smaller the dendrite spacing, the better the corrosion resistance of the coating layers. If the dendrite spacing of galvalume steel is greater than 20μm, the corrosion resistance of the product is poor.

With unique formula of the coating and control of coating thickness, the dendrite spacing of Shinmade galvalume steel is 10-15μm under electron microscopy, and the corrosion resistance of the product is excellent.

Ideal coating structure

 

The coating structure of Shinmade’s products is a staggered skeleton, which has good density and can prevent the intrusion of rainwater and other corrosive media, and that is why the product has good corrosion resistance. If the coating structure is bamboo-like, which means the coating layer is not dense enough and the corrosion resistance can be poor.

Small-sized and uniform spangle

 

The stability of crystallization determines the size and uniformity of spangles. The spangles are precisely controlled under the combined effects of the steel strip temperature, zinc liquid temperature, surface roughness, post-plating cooling, and special coating formula. The diameter of the spangle of Shinmade's galvalume is controlled between 0.5-3mm, which means the spangles are small-sized and uniform, and the appearance effect is more 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.
