What are the characteristics of S350GD ZM275 Zn-al-mg Steel Coil?

1. Zinc-aluminum-magnesium has extremely strong resistance to chlorine and alkali corrosion, and it has the characteristic of natural repair, and it will not have red rust within 20 to 30 years. appeared. Zinc-aluminum-magnesium has super anti-corrosion ability, and it is also resistant to stamping and is very compatible. Moreover, its surface friction and wear performance have also been improved a lot. Overall, its performance is more than a little better than that of ordinary steel coils, but its price is also relatively expensive.

2. Zinc-aluminum-magnesium steel coil contains MG, AL, and SI alloy elements, which improve the anti-corrosion effect of the entire coating from the base layer. Compared with ordinary galvanized products, its coating adhesion is very small, and it can better reflect very strong corrosion resistance.

3. And the coating around the cutting surface has a very dense protective film. This type of protective film has very low electrical conductivity, and it has certain effects on the cutting surface. Anti-corrosion effect. Its corrosion resistance is many times higher than ordinary ones, and it can heal itself. Moreover, the use of zinc-aluminum-magnesium coils will have a very long service life. Under normal circumstances, it can be used for more than 30 years.
