Tronrud Engineering was founded by Ola Tronrud in a workshop located on the ground floor of his house, in a residential area in Ringerike County (Norway).
For 7 years, Tronrud Engineering remained a one-man- business, and the customers were Norwegian factories and companies such as Raufoss, Jordan, Stabburet and Grorud Jernvare.
