Our company is a professional manufactuer copper grounding rods, using high-quality low-carbon steel core Q235, foreign-plated 99.9% pure copper production process, thus ensuring the copper layer and steel core molecular link between the permanent. With good conductivity, corrosion resistance and higher tensile strength.

           According to different environment, rational use of an effort to reduce grounding resistance, speed up the bulk flow purposes. This product is applicable to a wide range of long service life.

Technical parameters:

         (1) The copper layer thickness: ≥ 0.25mm

         (2) resistivity: ≤ 0.059Ωmm "

         (3) Tensile strength: ≥ 500N/mm

         (4) Corrosion resistance: the concentration of 10% nitric acid solution soak for more than 90 hours, no corrosion weight loss ≥ 15%

         (5) The copper layer adhesion: Continuous temperature over 300 up to 1 hour after the quenching, copper layer does not peel off.

         (6) The copper layer plasticity: The copper grounding rods bent 180 °, copper layer without cracks, without shedding phenomenon.
