Everyone knows that galvanized roofing nails need to be galvanized, and galvanizing is divided into two forms. Which galvanizing method should we choose? The following will give you a detailed introduction to the advantages and disadvantages.

The little-known galvanized roofing nails are available in two types of galvanized, hot-dip galvanized and electro-galvanized. They each have their own characteristics and each has its own shortcomings. The following small series will explain the two galvanized forms. The comparison so that you can more easily choose the one that suits you.

Comparison of performance between hot-dip galvanizing and electro-galvanizing

1. The electro-galvanized layer is relatively thick and uniform, indicating smooth and smooth. The zinc layer is relatively pure, can adapt to various environments, and has excellent corrosion resistance. The degree of corrosion in a strong acid and alkali environment is not very satisfactory.

2. The hot-dip method is nominally an iron-zinc-ion alloy layer, the zinc layer is tightly covered on the surface, and the surface iron-zinc mixed layer is very wear-resistant. The ductility is also good, and it can be processed by drawing and bending.

3. Hot-dip galvanizing is carried out in the state where zinc is also liquefied, that is, the roofing nail is placed in the layer of liquefied zinc solution. At high temperature, the iron and zinc on the surface of the roofing nail dissolve each other to form an alloy layer. With this time, the surface layer The zinc ions slowly diffuse into the iron and eventually cover the entire surface. The zinc solution on the surface cools to a layer of zinc.

4. Electroplating zinc is galvanized by moving the positive and negative ions of the electrode, and the positive and negative electrodes of the zinc solution in the liquefaction are docked with the negative electrode of the roofing nail, and the anion will move to the positive electrode under the action of current. The roofing nail itself is a steel body, and the zinc and steel form a micro-battery during electroplating, and the roofing nail steel body is protected by the cathode to form a plating layer.

The above is a comparison of the two galvanized forms, I really hope to help you.
