The aluminum-clad steel wire series is mainly used as good conductor ground wires, reinforcement cores for overhead power transmission conductors, optical fiber composite overhead ground wires (OPGW), and messenger wires in electrified railways. It is also applied to power fitting accessories, as well as guardrails and fences for highways, railways, sports venues and buildings, etc.

Aluminum-Clad Steel Wire: Commonly referred to as AS (Aluminum-clad Steel) wire, it is a solid round wire formed by uniformly and firmly coating a certain thickness of aluminum on the surface of steel wire. It features sound metallurgical bonding between steel and aluminum, serving as a high‑efficiency composite material. The aluminum-clad steel wire series is mainly used as good conductor ground wires, reinforcement cores for overhead power transmission conductors, optical fiber composite overhead ground wires (OPGW), and messenger wires in electrified railways. It is also applied to power fitting accessories, as well as guardrails and fences for highways, railways, sports venues and buildings, etc.
