How is the thickness of the copper plating typically selected? What are the differences between various thicknesses?

Release Time:2026-02-09

Common standard thicknesses are 0.25 mm, 0.3 mm, and 0.5 mm; some projects require a minimum of 1 mm.
Thickness directly determines the service life of corrosion protection: the thicker the coating, the better the corrosion resistance and the longer the service life, making it suitable for main grounding conductors that are not replaced over the long term.
Key selection criteria: assess soil corrosivity (normal soil vs. highly corrosive soil), design service life, and local lightning protection and grounding code requirements.
