A History of Steel Fabricators in Petrolia and Sarnia Area

John Duff Limited was founded by John A. Duff and Ove Bendixen in 1967. Originally located in Sarnia, Ontario, the company was named Bendixen and Duff. Soon after opening, the company moved its location to historic Petrolia where John Duff bought his partner out and renamed the business John Duff Limited. Today, after more than 50 years of service, John Duff Limited continues to operate a complete custom metal fabricating facility which services the  industrial. construction, manufacturing, commercial, and agricultural  industries.

As time goes by, we have seen many changes in the company: employees have come and gone, some customers’  businesses have closed and new businesses have discovered us. However, through it all, we have held to the original intention of John A. Duff, which is to work closely with our clients and be honourable in not only our words, but our work.
