Copper Clad Steel Strength & Conductivity

CCS combines copper's excellent conductivity/corrosion resistance with steel's high strength. Its tensile strength is 3-4 times that of pure copper (up to 850MPa), while offering significant cost advantages and anti-theft properties (low scrap value).

CCS has the high strength of steel to withstand mechanical stress when driven into the ground; the copper layer provides excellent corrosion resistance and conductivity. Compared to pure copper, it is less prone to theft and performs excellently in discharging high-frequency currents during lightning strikes due to the skin effect.

In many high-frequency applications (like coaxial cables), current flows primarily on the conductor surface (skin effect), so CCS performs almost identically to pure copper. In grounding systems, primarily for instantaneous discharge, its conductivity is fully adequate, and its strength advantage is more critical.

Our CCS products comply with international standards such as ASTM B452, ASTM B227, ASTM B910. We use the Clad & Weld process to ensure uniform copper layer thickness and metallurgical bonding with the steel core.
