Technology

Using the latest CAD and finite Element Analysis, Sturtevant models equipment to understand and eliminate stresses that could cause failure. Less carefully designed equipment could break down more often or fail catastrophically. Sturtevant takes these extra steps to protect company investments and their employees' safety.
