Expanded metal mesh is a kind of metal screen mesh, it also called Diamond Expanded Metal, Expanded Metal Sheet, etc. It belongs a classification of many metal mesh products that can be used in various industries.
Expanded Metal is very popular in our daily life and we can see it and touch it everywhere like stair tread step, platform, fence. We have to prevent rust to make these products more beautiful in the public sight.
Here are several ways to rust proof:
- It can be fixed into some elements to adjust the organization structure of the metal to achieve the purpose of anti-corrosion treatment.
- The surface of expanded metal can be covered with a protective film to achieve anti-corrosion effect. Common treatment methods are hot dip galvanizing, powder coated and so on.
- It is necessary to often wipe metal equipment in the process of use, or place desiccant in precision instruments and add a small amount of corrosion inhibitors that can slow down the corrosion rate in the corrosive medium.
Surface treatment of Expanded Metal:
- PVC coated
- Powder coated
- Hot dip galvanized(steel sheet is usually for hot dip galvanized)
- Paint
- PVDF (aluminum sheet is usually used for PVDF)
In the process of produce heavy duty expanded metal, we could add some elements to change the structure of metal. Add some anti corrosion and non-metallic material like oil, petroleum jelly, paint or enamel.
Or zine, chrominum and nickel arevcoated on the surface of the steel plate. After electroplating, hot dipping and spraying, a fine and stable protective film is formed on the surface of the steel by chemical method. For example, a black film is formed on the surface of machine parts, guns and other steel plates.
