DeWayne's counts some of the largest tier 1 automotive and heavy truck suppliers as customers. Corrosion protection on the interior of steel tubing has long been a vexing problem for many of these manufacturers. Over a period of years, DeWayne's has worked with both its suppliers and customers to research and develop a solution to this challenge. We've succeeded in developing a proprietary process that produces parts capable of offering interior corrosion resistance that can withstand 150 hours of humidity testing.
