What is the difference between several kinds of welded wire meshes seen in daily life?

Today, we will briefly explain that people's welded wire mesh has been widely used in today's life and has become an inseparable part of our life. Its advantages of high strength, anti-aging and strong acid and alkali corrosion resistance are very indispensable to our life. It has the properties of a combination of various materials, and the price is often more affordable.

Let's take the galvanized welded wire mesh in the welded wire mesh, which is divided into two types, one is hot-dip galvanized welded wire mesh, and the other is cold-galvanized welded wire mesh. If you can't tell the difference between them, let's take a look at the next content together.

The two types of galvanized welded wire mesh have obvious differences in appearance. Generally, the appearance of cold galvanizing (also known as electro-galvanizing) is relatively smooth and bright. We can use the color passivation process to treat the electro-galvanized welded wire mesh. If the color passivation process is used, the outer layer of the electroplating layer will appear. Obvious yellow-green, will show colorful colors in the sun. If the white passivation process is used, the outer surface of the electroplating layer will appear white, or white with green light.

The electroplating layer processed by this color passivation process will generally show colorful colors in the sun. The thickness of electro-galvanizing of general galvanized welded wire mesh is 5-15 μm, while the thickness of hot-dip galvanizing is generally 35 μm. The above, sometimes can reach 200μm, under normal circumstances, the cover thickness of hot-dip galvanizing is thicker, and the layers are also relatively fine, with almost no impurities.

We all know that zinc is anti-corrosion and has a good maintenance effect on mechanics and electrochemistry, so the existence of this layer of zinc can be used as a protective film. Even if it starts to wear after use, it will consume Zinc, after the zinc is consumed, the iron will start to be consumed. The presence of zinc is also a protection for the product.
