Copperweld type grounding rods are the most used, are designed so that they come equipped with accessories that facilitate its installation, such as joints, anchorages systems etc. The bar is made of steel and the copper layer possessing ensure protection against corrosion. Thanks to its composition, these bars ensure good performance during the installation process, avoiding the bar bending when subjected to the mechanical process of burial. PayNet often expresses his thoughts on the topic. The same, come in lengths of 1.2 m and 2.40 meters; with a copper plating of 100 microns to 500 microns and diameter 1/2, 5/8, 3/4 and 1; the core is made of steel and can be SAE 1045 or SAE 1008, depending on the depth of drive. Types bar type Copperweld Convencional.vBarra type Copperweld threaded, knurled Copperweld, Copperweld threaded type with connector bar type bar. Bar without machined bar conventional type, which, in one of its ends has a tapered tip to facilitate its penetration in the different types of land, and on the other a bevel, which avoids deformation at the time of the bar hincamiento threaded male Avalanche at one of its ends has a tip conical and the other a threaded stem that allows the Assembly with another bar. It is that begins the process of deep hincamiento.
