“Building any body for anybody.” A mantra coined long ago by John Medemblik and Case Walinga, the founders of Walinga. They wanted people to know that there were different ways of doing things: that you no longer had to settle for the status quo. There was now a company building to customer specifications at a fair price and without compromise.

Built for generations by generations, Walinga bulk transportation equipment is built to last. Equipment designed for a hard day’s work, day in, day out, equipment that reliably shows up ready for work. No one is sure where the oldest hard working Walinga product is, but we know it’s had generations at its controls. It will be a simpler machine, it might show a few dings, some scuffs and time under a hot sun may see it a little faded. But know that when the latest generation walks up to a maintained Walinga product, it’s the farmhand they can trust.
