After finish production, we can provide a range of surface treatment services, expanded metal surface treatment is also very important. According to construction application and customer requirement, we may make expanded metal maximum effect in practical application

 

cleaning and stain removal

As the expanded metal has small amount of oil stain after the production, it need to clean before surface treatment . The most common method is to use acid or a solvent of water rinsing. For the aluminum expanded metal, it will be ok just use one chemical cleaning to clean and dry

 

Galvanization

Galvanization is the most common application of a surface treatment. Galvanization is divided as hot galvanization and cold galvanization , commonly used as a protective layer approach, thus make the expanded metal corrosion resistance and elegant appearance.

 

oxidation treatment

The surface treatment is commonly used in aluminum expanded metal, various colours can be selected based on actual application and customer needs. After oxidation treatment, mesh surface is smooth, bright .

 

painting ,coating

After painting, coating, the expanded metal has good anti-corrosion, lubrication performance, and also prevent mesh or hole edge burr from stabbing and sketching.
