There are 4 different categories of Steel Coil Leveler. Starting from the most basic: straightening or flattening, this is the process of removing coil set or cross bow out of flat rolled material or a steel sheet. Generally, a flattener has 5 to 9 offset rolls, with relatively large diameter rolls. Typically a flattener is in press feed application, or used in a simple cut to length line.

Leveling is the process of straightening through a number of offset rolls, usually from *3 to *3, with a smaller diameter. Typically these machines are backed up with rolls behind the work rolls to minimize deflection.

Corrective leveling: This is configured like a basic steel coil leveler, however the back ups are fully adjustable to create bend in the rolls. A corrective leveler can reduce shape defects across the strip and remove all of the coil set. These levelers are *7 to *3 work rolls, and have adjustable back ups, some may have a 5HI or 6HI configuration for surface critical material such as painted, or stainless steel.

Tension leveling is the ultimate in corrective leveling, the material is run through a entry and exit set of bridle rolls, with the corrective leveler in between. The strip is under great tension with a slight elongation above the yield point of the material, and simultaneously leveled. The material is shape corrected and relieved of most internal stresses. This process usually involves a dedicated line.
