Treatment and coating of metals; machining

NACE v2.1 Code: C25.5

About treatment and coating of metals; machining

NACE code 25.5, 'Treatment and coating of metals; machining', represents a critical industry within the broader manufacturing sector. This industry is responsible for a wide range of processes that enhance the properties and performance of metal products, making them more durable, corrosion-resistant, and aesthetically appealing. The treatments and coatings applied in this industry are essential for a diverse range of end-use applications, from automotive components to construction materials, contributing significantly to the overall strength and resilience of the global economy.

Production process

The main production techniques used in this industry include electroplating, anodizing, painting, and other surface finishing processes. These methods are employed to apply protective coatings, enhance corrosion resistance, and improve the visual appeal of metal parts and products. In addition, machining processes, such as turning, milling, and grinding, are used to shape and refine the surfaces of metal components, ensuring precise dimensions and smooth finishes.

Production inputs

The key inputs required for this industry include a variety of raw metal materials, such as steel, aluminum, and copper, as well as specialized chemicals, paints, and other coating materials. Additionally, the industry relies on advanced machinery and equipment, including electroplating tanks, spray booths, and computer-controlled machining tools, to carry out the necessary treatment and coating processes.

Production outputs

The primary outputs of this industry are treated and coated metal products, which are then consumed by a wide range of other industries. These include 29.1 Manufacture of motor vehicles, 25.1 Manufacture of structural metal products, 28.1 Manufacture of general-purpose machinery, and 41.2 Construction of residential and non-residential buildings, among others. The coatings and surface treatments applied in this industry play a crucial role in enhancing the durability, corrosion resistance, and aesthetic appeal of the final products used in these downstream industries.
