The grounding copper bar must be connected and fastened with copper nuts and screws of the same material. So you should use copper screws.Ground line busbar copper terminal
Metal copper is used as the grounding copper row because copper is moderately costly in the metal used as a conductor, and is slower in air and water than iron and tin. The grounding resistance is small. Iron oxidizes faster in air and water, and has a higher grounding resistance.

Copper platoons, also known as copper busbars or copper busbars, are long conductors made of copper and have a rectangular or chamfered (rounded) rectangle (now rounded with rounded copper bars to avoid tip discharge). The circuit functions to carry current and connect electrical equipment.
