To know how Galvanized Wire Mesh is made, it is important to understand what the properties of Galvanized Wire are.

The galvanized wire has many advantages.

The galvanizing process protects the steel against oxidation.Steel wires protected against oxidation have a longer lifetime.It is produced by using materials harmless to health.Galvanization is an effective form of protection against metal corrosion, especially used for installations in the metal structures industry.

Of course, the quality of the zinc used here is also very important. Liquid zinc coating thicknesses vary. With the use of high-quality zinc, wire mesh fences will last for many years.Galvanized stainless steel is an incredibly durable and resistant material. Pipes, nails, beams, plates, bars, rods, and other industrial products are often galvanized to ensure decades of strength and corrosion prevention.Wire mesh plays a critical role in thousands of commercial and industrial applications. Galvanized screens, in particular, provide a lot of value, as they're adaptable, long-lasting, and reasonably priced.

The Process of Making Galvanized Wire Mesh:

A thick, robust outer layer of zinc is what makes galvanized hardware cloth so strong and resilient. How does it acquire this coating? It can be done in a couple of ways: hot-dipping and electrogalvanizing.

Hot-Dipping

1. The stainless steel is cleaned with a sodium hydroxide solution to remove dirt, debris, oil, and other residues.

2. An acidic solution is then used to remove any mill scale, rust, contaminants, and other surface impurities.

3. A zinc ammonium chloride cleaning agent (also known as a "flux") is applied to the surface to prevent oxidation. This solution remains on the steel, as it helps the zinc stick.

4. Next, the stainless steel is dipped into a vat of molten zinc (which has been liquified at an extremely high temperature).

5. The steel remains in the vat until it reaches the same temperature as the hot zinc.

6. After being removed from the vat, the stainless steel is rapidly cooled in a special tank.

Hot-dip galvanizing creates a physical and chemical bond between the steel and the zinc. This is what's called a zinc-steel alloy.

Electrogalvanizing

Unlike hot-dipping, electrogalvanizing is a cold process. Zinc particles are used to create an organic solvent, which is applied to the steel surface.This causes a reaction between the substances, resulting in a zinc-steel alloy. When the solvent evaporates, the zinc remains on the metal. Electrogalvanizing generally leaves a thinner zinc layer than the hot-dipping method.

Galvanizing Before vs. After Manufacturing Mesh

Stainless steel can be galvanized either before or after it's fabricated into wire mesh. When galvanizing occurs first, the metal is drawn down the desired diameter. The individual metal wires are coated with zinc and then woven or welded into screens. Welding can burn the zinc layer off at the joints, in which case it may need to be galvanized again.

When fabrication comes first, pre-woven steel products are dipped into molten zinc or coated with a solvent. This is usually the more costly option, particularly if mesh products are custom ordered and then galvanized. However, it ensures the mesh screens retain their protective coating.

Industrial Uses for Galvanized Mesh

Due to its notable durability and corrosion-resistance,the galvanized wire usage area is quite wide. It is especially used in different fields such as greenhouse cultivation, protection of agricultural lands, manufacturing of fence wires.
