Coil lines are machines used in the metalworking industry to process and shape coiled metal strips. These machines are used to cut, flatten, punch, and shape metal coils into various shapes and sizes. Coil lines are typically used in the production of sheet metal, piping, and other metal products. Some common types of coil lines include slitting lines, cut-to-length lines, and punching lines. Coil lines are essential equipment in the metalworking industry, helping manufacturers to produce high-quality metal products quickly and efficiently.

A leveller machine is a piece of industrial equipment that is used to straighten and level metal sheets or plates. It is commonly used in the manufacturing industry, particularly in the production of metal products such as automobiles, appliances, and construction materials. Leveller machines are typically large, heavy-duty pieces of equipment that use a series of rollers and blades to flatten and smooth out metal sheets. They are essential for ensuring that metal products are of uniform thickness, flatness, and smoothness, which is critical for their performance and appearance.
