Flat-rolled products of steel, not further worked than hot-rolled
CPC v2.1 Code: 4121
About flat-rolled products of steel, not further worked than hot-rolled
cpc code 4121 covers the production of flat-rolled steel products that have undergone hot-rolling but no further processing. This industry plays a crucial role in the broader steel manufacturing sector, providing essential raw materials for a wide range of downstream industries such as 4122 Flat-rolled products of steel, not further worked than cold-rolled, 4123 Flat-rolled products of steel, clad, plated or coated, and 4124 Bars and rods, hot-rolled, in irregularly wound coils, of steel. The output from this industry is a fundamental building block for many key economic activities, making it an important contributor to national and global industrial development.
Production process
The production of flat-rolled steel products under cpc code 4121 primarily involves the hot-rolling process. This process begins with steel slabs or billets that are heated to high temperatures, typically around 1200°C. The heated steel is then passed through a series of heavy, powered rollers that gradually reduce the thickness of the material, creating long, continuous sheets or strips of flat-rolled steel. The rolling process can be repeated multiple times to achieve the desired thickness and surface finish.
Production inputs
The main inputs required for the production of flat-rolled steel products under cpc code 4121 include raw steel, typically in the form of slabs or billets, as well as specialized rolling mill equipment and machinery. The steel used in this industry is often sourced from integrated steel mills or electric arc furnace facilities that produce the primary steel feedstock. Additionally, the production process requires significant energy inputs, such as natural gas or electricity, to power the rolling mills and maintain the high temperatures necessary for hot-rolling.
Production outputs
The primary output of the cpc code 4121 industry is flat-rolled steel products, such as sheets, strips, and plates, that have been hot-rolled but not further processed. These materials are then consumed by a variety of downstream industries, including 4122 Flat-rolled products of steel, not further worked than cold-rolled, 4123 Flat-rolled products of steel, clad, plated or coated, and 4124 Bars and rods, hot-rolled, in irregularly wound coils, of steel. The hot-rolled flat-rolled steel products from this industry serve as essential inputs for the manufacturing of a wide range of products, from automotive components to construction materials and household appliances.
