Iron or non-alloy steel; wire, plated or coated with zinc

HS v2022 Code: 721720

About iron or non-alloy steel; wire, plated or coated with zinc

HS code 721720 covers iron or non-alloy steel wire that has been plated or coated with zinc. This type of wire is widely used in a variety of industries, including construction, automotive, and electrical applications. It offers enhanced corrosion resistance and durability compared to uncoated steel wire, making it a popular choice for outdoor and exposed applications. The global market for zinc-coated steel wire is expected to grow steadily in the coming years, driven by increasing demand from developing economies and the need for more sustainable and long-lasting infrastructure.

Production process

The production of zinc-coated steel wire typically involves several key steps. First, the base steel wire is drawn to the desired diameter and tensile strength. The wire is then passed through a molten zinc bath, where a thin layer of zinc is deposited onto the surface. This process, known as hot-dip galvanization, provides a uniform and durable coating. In some cases, the wire may undergo additional processing, such as annealing or tension-leveling, to improve its physical properties and ensure consistent quality.

Production inputs

The main inputs required for the production of HS code 721720 wire include raw steel, zinc, and specialized wire-drawing and galvanization equipment. Steel producers and wire manufacturers must have access to reliable sources of high-quality steel, as well as a steady supply of zinc to maintain the coating process. Additionally, the production facilities must be equipped with specialized machinery, such as wire-drawing machines, galvanization tanks, and quality control equipment, to ensure the consistent production of zinc-coated steel wire.

Production outputs

The primary output of HS code 721720 is zinc-coated steel wire, which is used in a wide range of applications. This wire may be further processed or incorporated into various products, such as 731210 Wire rope, 731300 Barbed wire, 732010 Springs, and 732020 Coil springs. The zinc coating provides enhanced corrosion resistance and durability, making the wire suitable for use in outdoor, exposed, or harsh environments. The output of this industry is an essential component for many other industries, contributing to the overall development and infrastructure of the global economy.
