China ZAM Steel Coil

Product Details:

What issues should a user pay attention to when purchasing a ZAM steel coil?

Zinc, aluminum, and magnesium products are widely used. Different uses require different ordering standards, such as ① passivation + oiling, ② non-passivation + oiling, ③ passivation + no oiling, ④ non-passivation + no oiling, ⑤ Resistant to fingerprints, so during small batch procurement and use, it is necessary to confirm the usage scenarios and surface delivery requirements with the supplier to avoid subsequent processing problems.

Why is the surface brightness of the newly purchased customized galvanized aluminum magnesium steel sheet different from that of the previous inventory?

Zinc, aluminum, and magnesium production steel plants are also adjusting the brightness according to user needs. Some panel colors change from dark to light and some from light to dark. Therefore, there may be slight color deviations from different manufacturers and different batches.

Is the ratio of high aluminum and high magnesium necessarily the best?

High in magnesium and aluminum, the coating is brittle and has relatively good corrosion resistance. The salt spray test can reach 4,000 hours. However, there will be cracks when magnified under a microscope after bending. It is suitable for flat plate use; if bending, stamping, and other processing are performed during use. , it is recommended to choose a low aluminum and low magnesium solution because the coating is more flexible and the salt spray test can reach 3300 hours, making it the most cost-effective product on the market.
