Zinc-Based Alloy Steel Earth Rod
Zinc-Based Alloy Steel Earth Rod is a new product developed by our company. It effectively solves the pain points of traditional grounding materials, such as poor bonding performance, weak corrosion resistance, short service life, unbalanced corrosion potential between grounding components and building structures, and the need for additional cathodic protection. This product uses low-carbon steel and high-purity zinc as the main raw materials, and uses a special process to continuously cast the zinc layer to form a bimetal composite material. This product combines the anode characteristics of zinc with the advantages of traditional galvanized steel grounding materials. While ensuring efficient grounding conduction effect and anti-corrosion performance, it not only has the mechanical strength and thermal stability of steel, but also has the cathodic protection function of zinc.

⊙ Key Features
- · Efficient conductivity: The surface of the zinc-based alloy steel earth rodis densely coated with a layer of high-purity zinc. Since the conductivity of zinc is about twice that of steel, the zinc-based alloy steel earth rod has stronger conductivity than pure steel or hot dip galvanized material of the same diameter
- · Excellent anti-corrosion ability: Under the action of the external environment, zinc easily forms a dense protective layer on the surface, which effectively blocks further contact and penetration of electrolyte solution and slows down the process of zinc corrosion. The horizontal continuous casting process enables the zinc layer to be metallurgically bonded with the base steel, avoiding the galvanic effect of dissimilar metals commonly found in ordinary composite grounding materials, thus providing a better protective effect.
- · Cathodic protection: Since there is a certain thickness of zinc layer on the surface of the zinc-based alloy steel grounding rod, effective protection can be formed by sacrificing the low-potential zinc layer (sacrificial anode) during environmental corrosion, thereby achieving Cathodic protection.
⊙ Application Scenarios
- · Grounding grids of power systems: such as transmission line tower grounding, substation grounding, distribution transformer grounding and lightning arrester grounding, are especially suitable for areas with high soil resistivity or strong corrosiveness.
- · Communication and signal grounding: Comprehensive grounding systems in communication base stations, railway signal systems, subway platforms and tunnels require grounding bodies to operate reliably for decades without maintenance.
- · Petrochemical industry and hazardous environment: Lightning protection and anti-static grounding of gas stations, chemical plants, oil depots and natural gas stations require strict chemical corrosion resistance of materials.
