A client in the oil industry needed a part fabricated for a tank assembly. They came to G.E. Mathis Company, knowing we had the capabilities and expertise necessary to get the job done.

Our variable geometry, 3-roll, pinch-type plate roll machine enabled us to produce a high-quality, tight-tolerance cylinder segment in the most cost-effective manner.


The cylinder segment was made from A240-T304 stainless steel with a thickness of 0.375″ and a mill plate finish. It contained dimensional features of 300″ of inside radius thru 45 degrees by 96″ long. We cold formed the part by holding the tightest tolerances of ±0.1875″.

We performed first article, in-process, and final item inspection to ensure adherence to the customer-supplied print, along with the 2D CAD drawing. This project required the production of 32 cylinder segments within a three-week time frame.
