PR Series

Being in the metal industry you understand the demand there is for angle, tubing, pipe, channel, I-beam and other profiles in the manufacturing industry. Whether you are making a tanker trailer or a spiral staircase handrail the ability to roll profiles is essential to your business. WDM knows the demands that are placed on you to provide your customers with consistent, quality parts and products which is why we offer the PR Series. The PR Series takes WDM’s 35 years of knowledge making durable roll bending machines and combines that with a high production mindset. What you get is a heavy duty 3-roll pinch pyramid style angle roll where the 2 bending rolls are stationary and the top roll is the only moving variable. By limiting the die variables to just one setting you drastically increase the repeatability you can achieve even if the machine is operated by several different operators. The PR Series is highly recommend for large production applications where consistency is required from piece to piece.
