CPC v2.1 Code: 4124

About bars and rods, hot-rolled, of iron or steel

cpc code 4124 covers the production of hot-rolled bars and rods made of iron or steel. This industry is a crucial component of the broader metal manufacturing sector, providing essential raw materials and semi-finished products for a wide range of downstream industries. The bars and rods produced under this code are used in the construction, automotive, machinery, and other manufacturing sectors, making it a vital link in the global supply chain.

Production process

The production of hot-rolled bars and rods involves several key steps. First, raw materials such as iron or steel billets are heated to high temperatures in a furnace. The heated material is then passed through a series of rolling mills, which gradually reduce the cross-sectional area of the metal and elongate it into the desired bar or rod shape. The hot-rolling process imparts specific mechanical properties to the final product, such as increased strength and ductility.

Production inputs

The main inputs required for the production of hot-rolled bars and rods under cpc code 4124 include iron or steel billets, which serve as the raw material. Additionally, the industry relies on specialized rolling mill machinery, as well as energy sources such as natural gas or electricity to power the heating and rolling processes. Other important inputs may include lubricants, coolants, and various tools and equipment used in the manufacturing process.

Production outputs

The primary outputs of the industry covered by cpc code 4124 are hot-rolled bars and rods made of iron or steel. These products are then consumed by a variety of downstream industries, including 4311 Structural metal products, 4312 Tanks, reservoirs and containers of metal, 4313 Steam generators, and 4321 General-purpose machinery. The bars and rods produced under this code are essential for the construction, automotive, and machinery manufacturing sectors, among others.
