Product Detail

Sheet Metal Straightener (0.5-3.0mm)

Our sheet metal straightener, also known as a leveler or conventional straightener, is used to straighten uneven metal sheets. By passing the metal through upper and lower rollers, the machine achieves a smooth, flat surface through extrusion, particularly for strips or plates of specific thicknesses. Most levelers typically feature three or four rollers, along with transfer rollers at both ends. These machines are equipped with an adjustable handle on the upper part for precise fine-tuning of leveling thickness, ensuring high accuracy.
