Tinned Copper Clad Steel Flat Bar is a high-performance bimetallic conductor manufactured by metallurgically bonding a layer of high-purity copper onto a steel core, followed by a tin coating on the surface.

This triple-layer structure provides multiple advantages: the steel core ensures high mechanical strength, the copper layer delivers excellent electrical conductivity, and the tin coating enhances resistance to oxidation and corrosion.

Compared with bare copper clad steel, the tinned surface significantly improves durability in aggressive environments such as coastal areas, marine installations, and chemical plants. It also offers better solderability, making installation and connection more convenient.

The flat bar design provides a larger contact surface area, making it particularly suitable for grounding grids, earthing systems, and equipotential bonding applications.
