Muscle Shoals Rolling Mill Upgrade


Constellium completed a modernization and automation upgrade of its three-stand cold strip rolling mill in Muscle Shoals, AL, which is currently used to produce beverage cans. The modernization was carried out by AchenbachSES, a new joint venture company created by Achenbach Buschhütten in Germany, and SES LLC in Alliance, OH, which recently entered into an agreement to deliver rolling and slitting machinery in the U.S., Canada, and Mexico.

Rolling Mill Upgrade
The objective of the Constellium modernization project was to significantly improve the flatness of the rolled strip on its three-stand mill using electric discharge texturing (EDT) rolls and improved automation. These specialized work rolls will enable the Muscle Shoals operations to supply high precision strip. The characteristic feature of EDT strip is a lightly structured surface that allows for the high quality application of paint required by the automotive industry.

Supplier Partners
Achenbach-SES combines the technology and know-how from both companies. Achenbach Buschhütten is a family owned company with more than 100 years of mechanical engineering experience. It is renowned as a modern system provider of foil rolling mills and its associated auxiliary systems for aluminum and its alloys, as well as being a pioneer in foil slitting machines for metals and diverse compound materials.
