Iron or non-alloy steel; flat-rolled, width 600mm or more, corrugated, plated or coated with zinc (not electrolytically)

HS v2017 Code: 721041

About iron or non-alloy steel; flat-rolled, width 600mm or more, corrugated, plated or coated with zinc (not electrolytically)

HS code 721041 covers a crucial segment of the steel industry, encompassing flat-rolled iron or non-alloy steel products that are corrugated, plated, or coated with zinc (excluding electrolytic processes). These materials play a vital role in a wide range of industries, from construction and infrastructure to automotive and manufacturing, making them an essential component of the global economy.

Production process

The production of the materials covered under HS code 721041 typically involves a multi-step process. First, the steel is rolled into flat sheets or plates, often using a hot or cold rolling process. The sheets are then corrugated, a technique that involves passing the steel through a series of rollers to create a wavy or ridged surface. Finally, the steel is coated with zinc, either through a hot-dip galvanization process or an alternative coating method, to provide enhanced corrosion resistance and durability.

Production inputs

The primary inputs for the production of HS code 721041 materials include iron or non-alloy steel, as well as zinc for the coating process. Specialized rolling and corrugating machinery are also essential, along with energy sources and other supporting infrastructure. The availability and quality of these inputs can significantly impact the production capacity and cost-effectiveness of this industry.

Production outputs

The flat-rolled, corrugated, zinc-coated steel products covered under HS code 721041 are widely used in a variety of applications. They are commonly found in construction, particularly in roofing, siding, and other building components. These materials are also used in the manufacture of 761010 Aluminium structures and parts of structures and 730890 Structures and parts of structures, of iron or steel, n.e.s., as well as in the automotive industry for body panels and other vehicle parts.
