Metal-rolling mills; tube mills

HS code 845510 covers metal-rolling mills and tube mills, which are essential equipment in the metalworking industry. These machines play a crucial role in shaping and processing various metal products, from steel sheets and bars to seamless tubes and pipes. The metal-rolling and tube mill industry is a key component of the broader manufacturing sector, supporting the production of a wide range of goods, from construction materials to automotive parts and industrial machinery.

Metal-rolling mills and tube mills utilize a variety of techniques to shape and form metal. The most common process is rolling, where the metal is passed between two or more rotating cylindrical rolls to reduce its thickness and alter its shape. Tube mills, on the other hand, are specifically designed to produce seamless tubes and pipes by continuously feeding a metal strip or sheet through a series of rollers and dies. These specialized machines can create a wide range of tube sizes and profiles to meet the diverse needs of various industries.

The metal-rolling and tube mill industry relies on a steady supply of raw materials, primarily various types of metal such as steel, aluminum, and copper. In addition to the metal feedstock, these mills require specialized machinery, including the rolling stands or tube-forming equipment, as well as supporting infrastructure such as furnaces, cooling systems, and material handling equipment. The industry also depends on a skilled workforce capable of operating and maintaining the complex machinery involved in the production process.

The primary outputs of the metal-rolling and tube mill industry are a wide range of metal products, including sheets, plates, bars, and seamless tubes and pipes. These outputs are then consumed by a variety of downstream industries, such as 870000 Vehicles, 730000 Articles of iron or steel, and 840000 Machinery, where they are further processed or incorporated into final products. The versatility of these metal products makes the metal-rolling and tube mill industry a crucial supplier to many sectors of the economy.
