KO Custom Fab was founded in 1999 by Owner, Ken Oliver. It was part time for the first 4 years while Ken was working as second in command at Redi-Fab, Inc, a steel fabricator in Portland, OR. After 4 years of part time, he moved KO Custom Fab to full time and grew it to what it is today. As one of the leading Structural Steel fabricators in the Portland area, we attribute our success to the lasting customer relationships we’ve developed throughout the years. We believe that all of our customers deserve the highest level of service, and we are committed to providing just that. We have been at our current location since 2010.
