Copper plated steel tube is made of high quality seamless tube, and the electrolytic copper molecules with 99.9% content are uniformly covered on the low carbon steel core, so that the copper and steel core are fully bonded. It has the characteristics of thick copper layer, good adhesion and non - stripping. Its advantages are large tensile strength, strong corrosion resistance (can guarantee service life in more than 50 years). Copper-plated steel tubes are highly protective after being buried underground, either through natural corrosion or electrochemical reaction. The copper plated steel tube and the grounding wire are welded by hot flux, so that the grounding device is completely protected by copper, which makes it a real maintenance-free grounding device.
