Zinc-Clad Steel Grounding Product

Brief Introduction:

The Zinc-Clad Steel Grounding Product is a bimetallic composite grounding material developed to extend the service life of grounding systems. It is manufactured by bonding a thick layer of zinc onto a low-carbon steel core through a specialized continuous casting cladding process.

This unique combination provides the mechanical strength of steel and the excellent corrosion resistance of zinc. The corrosion resistance of zinc-clad steel is up to seven times greater than that of conventional steel grounding materials. In addition, its excellent ductility ensures that the zinc layer remains firmly bonded during installation and operation, improving construction efficiency and long-term reliability.

The product is widely used in grounding systems and cathodic protection applications, particularly in harsh and highly corrosive environments.

Characteristics:

Zinc-clad steel composite grounding material utilizes a low-carbon steel core, providing excellent mechanical strength and thermal stability while ensuring reliable fault current dissipation.

Zinc, as the cladding metal, offers electrical conductivity approximately 25 times greater than steel, resulting in improved grounding performance.

The zinc surface layer provides outstanding corrosion resistance, significantly extending the service life of the grounding system.

When the zinc layer thickness exceeds 3 mm, it can function as a sacrificial anode, protecting grounding grids, underground metal structures, pipelines, and related steel equipment from corrosion.

Excellent ductility and adhesion ensure that the zinc coating will not peel or separate during transportation, installation, or service.

Zinc possesses anti-sparking characteristics, allowing installation without generating sparks and improving safety in sensitive environments.

Suitable for long-term operation in aggressive soil and underground conditions.

Applications:

Grounding systems in power transmission, distribution, and substations.

Cathodic protection systems for underground metallic structures.
