What is the difference between galvanized welded wire mesh and stainless steel welded wire mesh?

As we all know, the biggest advantage of stainless steel welded wire mesh is its rust resistance. Even though the price of stainless steel welded mesh is high, its market share is large due to its excellent properties. However, galvanized welded wire mesh also has the ability to resist corrosion and rust, and the price of galvanized wire mesh is also lower. Can galvanized welded wire mesh replace stainless steel welded wire mesh? What's the difference between the two of them?

Stainless steel welded wire mesh is made of high-quality low-carbon steel wire row welding, surface passivation, plasticization treatment, smooth mesh surface, uniform mesh, firm solder joints, local machining performance, good, stable, anti-corrosion, anti-corrosion.

The cold galvanizing process of galvanized welded wire mesh is used to protect the metal from corrosion. To this end, a coating of zinc filler is used. It is applied to the protected surface by any coating method, and after drying, a zinc filler coating is formed. Zinc content (up to 95%) in the dry coating. Suitable for repairmen.

Material:

The main difference between stainless steel welded wire mesh and galvanized welded wire mesh is the material. Most metals will oxidize when exposed to oxygen. The surface of stainless steel welded wire mesh will be passivated, and the welded wire mesh will have the ability to resist rust. If this layer of passivation is destroyed, the metal inside will be oxidized when it encounters oxygen, so as to protect it from rusting inside. It is equivalent to self-healing and self-protection.

Galvanized welded wire mesh, which is essentially iron wire, is plated with a layer of metal to prevent oxidation, zinc. After the zinc layer is scratched, the internal iron wire will be exposed, so the rust will spread inward from the scratched part, and the iron wire will not have a protective film like stainless steel. So the rust will get worse and worse. Galvanized welded wire mesh does not mean that as long as it is properly galvanized, it will not rust. After all, it is only a layer of zinc. When the oxidation reaches a certain level, it will rot. Cold galvanized welded wire mesh, good-looking, easy to rust, hot-dip galvanized welded wire mesh, white surface, particles, impurities, not good-looking, but can be used for 3 to 4 years, depending on the usage. Stainless steel welded wire mesh is conservatively estimated to use stainless steel welded wire mesh of suitable material in a certain environment for more than 15 years

There is a layer of zinc on the surface of the galvanized welded wire mesh, so it has the effect of anti-corrosion. According to the thickness of the galvanized layer, the galvanized welded wire mesh is divided into two different varieties: hot-dip galvanized and cold-galvanized. Zinc mesh is better. Although this galvanized welded wire mesh also has very good corrosion resistance, it is inferior to stainless steel welded wire mesh in some aspects.

Even though galvanized welded wire mesh has strong corrosion resistance, it cannot completely replace the role of stainless steel wire welded wire mesh. Stainless steel welded wire mesh not only has good corrosion resistance, but also has much better performance than galvanized welded wire mesh in many other aspects. Because there is a layer of zinc on the surface of galvanized welded wire mesh, it will be slightly toxic and cannot be used in some places. For example it cannot be used in certain scientific studies or in the pharmaceutical, food and other industries.

Packaging Most welded wire meshes are made of moisture-proof wrapping paper. There will be certain product descriptions for welded wire meshes on the wrapping paper, including manufacturers and specifications. There are many different specifications, and the diameter is generally between 3 meters and 6 meters. This kind is generally very thin, and the flexibility is very good, and the use is very wide.
