Multi-roll cold mill stands are described using different terms depending on their type and manufacturer: 12 and 20 roll stand Z-High® S-High. Multi-roll cold rolling mills are used to process high grade steel strip and non-ferrous metal strip. In order to prevent whipping of the work rolls, they are supported by means of intermediate

Less compression - better surface. In order to obtain a reflective surface cold rolled aluminum sheet, at last pass perform its minimum compression. The most shining surface obtained by applying well-polished working rollers. A typical cold rolling mill with a single roll stand may sheet at about 1500-1850 meters per minute for each passage.

Aluminum plates pass through a continuous rolling mill to further reduce plate thickness. The final step for the aluminum sheet is cold rolling, where aluminum sheets are compressed between two rollers, reducing material thickness up to 50%. Cold rolling eliminates surface imperfections, enhances flexibility, and improves plate strength.
