Product introduction: Copper Coated Steel Earth Rod is the new product with introduction of our advanced plating process, thick copper layer, low resistance, strong corrosion resistance, high strength, easy to install and connect electrical properties, good adhesion degree, not to divest ( can be rolled thread) and so on. It has the advantage of great tensile strength (tall and 600 N / mm), strong corrosion resistance (guaranteed service life of 30 years), with a constant low resistance and good plasticity, both high-conductivity copper and properties of steel. The electric plating series products overcome the existing law casing coated poor bonding defects, can be used in power transmission and communication lines, power plants, buildings and ground antenna device, can also be used for computers and other electronic equipment grounding system. Also, it can be used as grounding for lightening equipment with lightning, lightning-line device. Copper grounding rods features: 1, a perfect combination of elements in the bar continued: cold drawn by the solid steel bars on the first layer of nickel plating, nickel plating on the floor of the same thickness of copper, nickel and copper and just have a good performance bond, which ensure that the layer of copper and steel combination; 2, high-intensity, for deep drilling, and thus easy to break into the ground, hardly break down, not falling; 3, as copper is extremely decay resistance, EST copper grounding bar decay of good performance; 4, copper layer and the perfect combination of steel, copper layer on the surface to 25 times the hole did not detect a magnifying glass; 5, product life expectancy of more than 30 years; 6, the construction is very convenient to use mechanical or construction manua
