Weinrich Truck Line, Inc. has been in business since 1919. The firm was started by Sam Weinrich with the philosophy of "serving our customers with service." and three generations later our trademark is still "service". Sam's son, Ray, took over in 1944. The third generation, Bill, and his wife, Donna, assumed control in 1960. 

The original company operated principally in and around the Sioux City, Iowa, area hauling grain and feed ingredients.

Today, Weinrich Truck Line specializes in food grade tanks and dry vans.
