Coil/Stock Straightening Machines

Production Resources offers 7, 9, 11,19,  and 21 roll straighteners designed primarily to remove coil set and reduce crossbow. The 19 and 21 roll models approach the performance of levelers. We also offer coil straightener lines specially designed for HSLA steel applications.

Material type, tensile strength, thickness, cross section, and line speed all affect straightener requirements for roll spacing, roll diameter, number of rolls, and horsepower.

Our Application Engineers can help you select the right coil straightener for your requirements. Contact us today for the assistance you need.
