Copper expanded metal is a lightning protection method that can not only act as a receiver to receive lightning, but also act as a down conductor to conduct lightning well.

Product Features
As an important lightning protection method, lightning protection metal mesh has achieved very important applications in aircraft. The common metal mesh for lighting protection includes woven mesh, copper expanded metal foil and perforated sheet. The disadvantage of the woven mesh is that the surface of the composite curvature is difficult to cover, which affects the aerodynamic performance, and the lap resistance between the metal wires of the woven mesh is relatively large, and the lightning protection effect is far less than that of the copper expanded metal. The woven wire mesh is also prone to breakage and disintegration due to the strong electromagnetic force generated by the lightning current.
Scope of application
Important application of copper expanded metal:
Aerospace
Wind Energy
Battery mesh
Electrolyzer
Filtration
EMI shielding
Automotive
flue gas denitrification
Perforated Metal Noise Barrier Perforated Metal Noise Barrier is also called perforated sheet or punched metal plate. It is a little similar with expanded metal mesh, but not same.
