About doors, windows and their frames and thresholds for doors, of iron, steel or aluminium

cpc code 4212 covers the production and trade of doors, windows, and their associated components made of iron, steel, or aluminum. This industry plays a crucial role in the construction and renovation sectors, providing essential building materials that contribute to the functionality, aesthetics, and energy efficiency of residential, commercial, and industrial structures. As a key supplier to the broader construction industry, the 4212 sector is closely tied to broader economic trends and the health of the real estate market.

Production process

The production of doors, windows, and their frames and thresholds typically involves a combination of metalworking techniques, such as cutting, shaping, welding, and finishing. Manufacturers may utilize automated machinery and computer-aided design (CAD) software to streamline the production process and ensure consistent quality. The specific techniques employed can vary depending on the material, design, and intended application of the final product.

Production inputs

The main inputs required for the 4212 industry include raw materials such as iron, steel, or aluminum, as well as various hardware components like hinges, locks, and weatherstripping. Manufacturers may also rely on specialized tools, machinery, and energy sources to facilitate the fabrication and assembly of these building components. Additionally, the industry may consume outputs from related sectors, such as 2410 Basic iron and steel, 2420 Tubes, pipes, hollow profiles and related fittings, of steel, and 2511 Structural metal products, which provide the necessary materials and components.

Production outputs

The primary outputs of the 4212 industry are doors, windows, and their associated frames and thresholds, which are then consumed by the broader construction industry. These products are used in the construction and renovation of residential, commercial, and industrial buildings, as well as in the production of other related building components. The outputs of the 4212 industry may be further processed or incorporated into the final construction projects, which are classified under codes such as 4120 Construction of residential and non-residential buildings and 4211 Construction of roads and railways.
