Tinned copper conductors, tinned copper flats are first electroplated with copper, followed by electroplating tin on the copper layer. This process ensures a permanent molecular bond between the tin layer, copper layer, and steel core, without any physical gaps or defects. It guarantees the integrity of the conductor, effectively preventing issues such as peeling, cracking, and detachment during installation and laying.

Tinned copper flat steel, due to the tin layer on its surface, effectively prevents oxidation of the copper layer, enhancing the anti-corrosion performance of the grounding conductor and extending the service life of the entire grounding grid. Additionally, because the surface color of the tinned copper conductor resembles that of ordinary galvanized materials, it is not easily distinguishable, making it less likely to be considered valuable outdoor and, therefore, less prone to loss.
