Structural metal products and parts thereof

CPC v2.1 Code: 421

About structural metal products and parts thereof

cpc code 421 covers the production of a wide range of structural metal products and parts, which are essential components in various industries such as construction, manufacturing, and infrastructure development. This industry plays a crucial role in the broader economy, providing the necessary building blocks for the construction of buildings, bridges, machinery, and other vital structures.

Production process

The main production techniques used in this industry involve the fabrication, welding, and assembly of metal components. This typically includes the cutting, shaping, and joining of steel, aluminum, and other metal alloys to create the desired structural elements. Advanced manufacturing processes like computer-numerical control (CNC) machining and robotic welding are commonly employed to ensure precision and efficiency in the production of these metal products.

Production inputs

The key inputs required for the structural metal products industry include raw materials such as steel, aluminum, and other metal alloys, as well as specialized machinery and equipment for cutting, shaping, and joining the metal components. Additionally, this industry relies on skilled labor, including welders, fabricators, and engineers, to design and manufacture the various structural metal products.

Production outputs

The primary outputs of the structural metal products industry are a diverse range of structural metal components, including beams, columns, trusses, and other load-bearing elements. These products are then consumed by various other industries, such as 230 Construction of buildings, 231 Civil engineering, and 281 Manufacture of general-purpose machinery, which incorporate them into their own products and projects.
