What are the 3 Types of Galvanized Expanded Metals?

Have you ever required the galvanized expanded metals before? Do you know there are 3 types of galvanized expanded metals for meeting different requirements? Now let us explain for you what are the 3 types of galvanized expanded metals.

As we all known, expanded metal mesh is formed by slitting and stretching process, so do galvanized expanded metals. They can be anti- rust and become the cost effective and long term protective solution of expanded metal. Galvanized Expanded Metal is used in a variety of specialty applications, such as lawn furniture,book and storage shelves, lamps and lamp shades, fireplace screens, many types of grilles, occasional tables, folding screens, room dividers, and air filtration filters.

According to the materials and quantity of zinc coating, there are 3 types of galvanized expanded metals.

1. The material is galvanized sheet, then the galvanized expanded metals are stretched on the machines directly, the quantity of zinc coating is about 40g per square meter.
2. The material is low carbon steel ( or black steel ), then the expanded metals are made on the machines, then the expanded metals shall be cold galvanized ( or eletro galvanized ) by the galvanizing line, the quantity of zinc coating is about 40g per square meter.
3. The material is low carbon steel ( or black steel ), then the expanded metals are made on the machines, then the expanded metals shall be hot dipped galvanized by the galvanizing line, the quantity of zinc coating is at least 300g per square meter.

Some people may wonder, what the difference between galvanized material expanded metal and cold galvanized expanded metals, because they are both with about 40g zinc coating quantity. The different is on the surface of the expanded metals, it looks brighter for galvanized materials expanded metals, while it looks darker for cold galvanized expanded metals, and the price of cold expanded metals is usually a little expensive than galvanized materials expanded metals, because galvanized after can guarantee the zinc to be coated in every corner of the expanded metals, but there will be some lose of zinc during the production of the galvanized materials expanded metals.

And you may notice the zinc coating of the hot dipped galvanized is at least 300g, which means when you need 400g, 500g or even more like 700g, 900g zinc coating of the expanded metals, that will definately be hot dipped galvanized.

One more thing need to be say is that both galvanized materials expanded metals and cold galvanized expanded metals can be made into both rolls and sheets, but the hot dipped galvanized expanded metals can only accept sheets instead of rolls because of its hot dipped treatment technical way.

Now you must have a clear view on the 3 types of galvanized expanded metals, then you can choose the right and economical way according to your detail requirements. The worse the environment is, the more zinc it will need. So our choice on the galvanise is on the humidity of the environment. Am I understood?
