Iron or steel wire; grill, netting and fencing, plated or coated with zinc

HS v2017 Code: 731441

About iron or steel wire; grill, netting and fencing, plated or coated with zinc

HS code 731441 covers a range of iron or steel wire products, including grills, netting, and fencing, that are plated or coated with zinc. These products are widely used in construction, infrastructure, and industrial applications, playing a crucial role in the broader economy. The zinc coating provides enhanced corrosion resistance, making these products durable and long-lasting, which is essential for their diverse applications.

Production process

The production of HS code 731441 items typically involves several key steps. First, the base material, which is iron or steel wire, is drawn to the desired thickness and shape. The wire is then subjected to a galvanization process, where it is coated with a layer of zinc. This zinc coating can be applied through various methods, such as hot-dip galvanization or electro-galvanization. Finally, the coated wire is woven or fabricated into the desired grill, netting, or fencing products.

Production inputs

The main inputs required for the production of HS code 731441 items include iron or steel wire, zinc, and specialized machinery for wire drawing, galvanization, and weaving or fabrication. The quality and properties of the base wire, as well as the efficiency of the galvanization process, are critical factors in determining the final product's performance and durability.

Production outputs

The primary outputs of HS code 731441 are zinc-coated iron or steel wire products, such as grills, netting, and fencing. These items are widely used in construction, infrastructure, and industrial applications, where they provide protection, security, and structural support. The outputs of HS code 731441 may be consumed by industries covered under other HS codes, such as 730820 Structures and parts of structures, of iron or steel; towers and lattice masts, 730900 (Reservoirs, tanks, vats and similar containers for any material (other than compressed or liquefied gas), of iron or steel, of a capacity exceeding 300 l, whether or not lined or heat-insulated, but not fitted with mechanical or thermal equipment), and 732690 Other articles of iron or steel, among others.
