ZAM steel coil

ZAM galvanized aluminum-magnesium steel coil is mainly used to replace stainless steel products and improve the performance of galvanized sheets.
ZAM is a new type of environmentally friendly steel sheet with high corrosion resistance. It can still maintain the original appearance of the steel sheet in a harsh corrosion environment, reducing the post-processing process of general steel and reducing the subsequent cost of use. At the same time, due to the reduction of electroplating, the product saves resources and protects the environment.
Because ZAM steel coil saves a lot of processes, it saves a lot of post-processing costs for future processing and maintenance, and is very environmentally friendly. This product is excellent in salt spray test and red rust resistance.
Galvanized aluminum-magnesium steel coil ZAM has several advantages:
1. ZAM’s anti-rust performance is 10-20 times that of galvanized sheet (reaching stainless steel standards)
2. ZAM reduces costs (generally 40% cheaper than stainless steel)
3. ZAM has good corrosion resistance (the cut can be automatically repaired to prevent red rust, one of the biggest features)
4. ZAM has good processing performance (due to its excellent wear resistance and scratch resistance, it can adapt to various processing)
5. ZAM is environmentally friendly (passed many international environmental tests)
6. ZAM thickness, strength and galvanizing amount can be adjusted
7. ZAM has a long service life.

Stainless steel forms an inert film on its surface, which has excellent corrosion resistance. However, its disadvantage is that it is weak to “salt”. The protective film of galvanized aluminum-magnesium steel coil can also play a strong barrier effect against “salt”. Stainless steel is superior in “steel life” required for “perforation resistance” and other structural uses. However, ZAM galvanized aluminum-magnesium steel sheet is extremely excellent in “red rust resistance” when used as a panel surface.
The corrosion resistance of aluminum, which is very resistant to corrosion, is also achieved by the inert film on its surface. However, aluminum has the property of being weak to “alkali”.

ZAM commonly used materials include S350GD, S390GD, S420GD, S450GD, S550GD, 51D, etc.
