What is Expanded metal mesh sheet?
Expanded metal sheet is a kind of wire mesh, processing by sheet metal punching machine, and then form the material sheet into the network status, that wire mesh is called Expanded metal mesh, or Expanded metal sheet.
The type of Expanded metal mesh includes Raised expanded steel mesh, (also called Standard or Regular expanded metal mesh) and Flat expanded metal.
The Raised expanded metal mesh has Diamond openings, and it is slightly raised on surface.
Flat expanded metal mesh is manufactured throught Raised one. The workers pass the standard expanded sheet into a cold roll reducing mill, then forming diamond openings with flat surface. You could find the difference from the following two photos:
How is the Expanded metal mesh producted?
Expanded metal sheet is made from kind of metal sheet, with the process of stamping and tensiling. Expanded mesh mesh forms a variety of diamond shaped openings as per customized sizes. In general, owing to the expanding process, the metal sheet could be expanded up to 8 times its original size, losing up to 75% original weight per meter, therefore, it has the advantage of less weight, more economical than a single metal sheet.

The expanded metal mesh has the following advantages:
1. Visibility and colorful surface treatment
2. Not easy to damage or hurt by Rainstrom or insolation
3. Anti-corrosive
4. Less weight and could be beared for outside wall cladding
5. Beautiful surface and long usage, used as decorative mesh for building external wall
Because of all its advantages, the Expanded metal meshes are widely used in Walking for solor system, for platform, railway, road, civil building construction, and water conservancy project. The expanded metal mesh can also be used in external wall decoration and chemical industry, filter, etc.
