New York, January 20, 2026 – Aluminum-clad steel strand has become one of the most widely used high-performance metal products in global power, communication, railway, and coastal engineering projects, thanks to its excellent mechanical strength, light weight, and outstanding corrosion resistance. Industry analysts predict that global demand for aluminum-clad steel strand will maintain an annual growth rate of more than 7% from 2026 to 2030, driven by the expansion of cross-border power grids, offshore wind farms, and 5G communication infrastructure.
Aluminum-clad steel strand is formed by metallurgically bonding aluminum layer to high-strength steel core, combining the high tensile strength of steel and the excellent corrosion resistance and conductivity of aluminum. Compared with traditional galvanized steel strand, it has stronger resistance to salt spray, humidity, and industrial corrosion, and its service life can reach 30 to 50 years in harsh environments.
In the power industry, aluminum-clad steel strand is mainly used for overhead ground wires, messenger wires, and long‑span transmission lines. It can withstand strong winds, ice loads, and extreme temperature changes, while effectively reducing line faults caused by corrosion. Many UHV and cross-border transmission projects in Asia, Africa, and South America have chosen aluminum-clad steel strand as the preferred supporting material.
In communication engineering, aluminum-clad steel strand serves as an ideal load-bearing component for overhead communication cables and optical fiber lines. Its light weight reduces the load on towers and poles, while its high strength ensures stable operation under typhoons and heavy snow. With the rapid construction of 5G and broadband networks worldwide, the demand for high-quality communication supporting strands is increasing rapidly.
In coastal and marine engineering, aluminum-clad steel strand shows unique advantages. It is widely used in port facilities, offshore wind turbine foundations, coastal power grids, and cross-sea communication links. Its superior corrosion resistance greatly reduces maintenance costs and extends the service life of infrastructure in salt‑fog environments.
Leading manufacturers are continuously improving production processes, such as precision cladding technology, optimized stranding structure, and online quality control systems, to improve product stability and consistency. More enterprises are also developing high-strength, ultra-thick cladding, and low-loss products to meet the higher requirements of modern infrastructure.
Industry experts said that aluminum-clad steel strand will continue to expand its application scope in the next five years. With the global promotion of low-carbon energy transformation and the acceleration of intercontinental infrastructure interconnection, aluminum-clad steel strand will play an increasingly important role in power transmission, communication networks, new energy projects, and cross-border engineering.
