For years anyone who slits, tins, forms, stamps, shapes, or otherwise processes flat-rolled product have struggled at times with flatness issues.  I have found a nice online article about Flatness and Leveling @ http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=436. The source is trade magazine “The Fabricator’  a industry source I have subscribed to for years. I believe you will find this article a solid, clearly written source of information regarding the struggle we all fight with flatness issues.

Please note ABC Metals can roller level and/or tension level flat rolled product ‘In-House’ with short lead times available. Tension leveling is our preferred solution to most flatness requirements. For more information please contact us at 800-238-8470 or on the web @ www.abcmetals.com
