Nickel and Hard Chrome Rod

The nickel and chrome plating technology is the solution to extreme environments with intense corosion: 

Offshore, marine conditions

Military applications, wind, solar and aerospace sector

Agriculture, mining industry, oil and gas industry

The nickel layer is completely free of cracks, pores and by this, the base material is isolated from the atmospheric corrosion, while the chrome layer ensures a very good wear resistance.
