Advantages of Zinc-aluminum Alloy Gabion Mesh

Hot-Dipped Galvanized Gabion Mesh and Zinc-Aluminum Alloy Gabion Mesh are two common types of gabion mesh. The differences in their manufacturing processes directly affect their performance and applications.

1.Differences in Manufacturing Processes

Hot-Dip Galvanizing Process:

• Principle: The hot-dip galvanizing process involves immersing steel wire in molten zinc, forming a zinc coating. The zinc layer directly coats the surface of the wire, preventing corrosion from air and moisture.

• Process: Hot-dip galvanizing is a simple process with relatively low cost. The steel wire is immersed in a zinc bath at high temperature, where zinc reacts with the steel to form a metal compound, creating a zinc coating on the wire surface.

Zinc-Aluminum Alloy Process:

• Principle: The zinc-aluminum alloy coating is formed by immersing the steel wire in a zinc-aluminum alloy bath or spraying the alloy coating. This process combines about 5%–15% aluminum with zinc to create a more corrosion-resistant alloy layer.

• Process: The manufacturing process for zinc-aluminum alloy coatings is more complex. The steel wire is first coated with zinc, and then it undergoes an alloying process with aluminum to form an even zinc-aluminum alloy layer. Alternatively, coating and spraying techniques can be used to apply the alloy.

  
  

2.Advantages of Zinc-Aluminum Alloy Compared to Hot-Dip Galvanizing
Zinc-aluminum alloy has superior corrosion resistance, higher temperature resistance, and a longer protection period compared to hot-dip galvanizing. It performs especially well in environments such as seawater, high humidity, and acid rain.
