AK Steel’s tubemaking subsidiary, AK Tube LLC, Walbridge, Ohio, has signed a definitive agreement to acquire an exhaust tube manufacturer located in Columbus, Indiana. AK Tube plans to acquire Central Tubing Facility (CTF) from a subsidiary of ArvinMeritor. No details of the purchase agreement, which is subject to regulatory approval, were disclosed. The companies expect to complete the transaction, which includes a multi-year supply agreement between AK Tube and ArvinMeritor, during AK Steel’s third quarter. CTF produces stainless steel tubing used primarily in the manufacture of passenger and light truck exhaust systems used throughout the USA and Canada. The Columbus facility began production in 1996 and was expanded in 1998.
