Our History

Original Wood Truss Airport Hanger with add on Rebar Shop: Carlisle Steel Supply/Carlisle Supply

Ritner Steel started on the Ritner Highway by my father Louis Dorbian under the name of Carlisle Steel Supply in 1948.  Dad was originally from Saint John, New Brunswick. He served in World War II. Click to view his amazing itinerary.

After the war, he came to Harrisburg through family connections.  Soon after, he married my mom “Dottie” and settled in Harrisburg. Click to view photo of my parents.

In 1948 with support from family, dad purchased a small “wooden truss”  airport hanger to start his business located in R.D. 5 Carlisle on the Ritner Highway.

In 1973, after graduating from Penn State, I went to work with dad. He was not in the best of health, and I had a responsibility to uphold.

I lost dad in 1976 at the age of 58. Dad’s work gave me a foothold into the steel business along with the opportunity to try and create new possibilities from what he started.

Initially I built and developed a rebar fabrication business and building supply company to go along with the steel business. During this period, I had renamed the company to Carlisle Supply. In 1990, I sold the rebar and building supply part of the business and relocated from the Ritner Highway.

The new company name became Ritner Steel.

From 1992 to 1997, we were located on Claremont Road. In 1998, I purchased the facility of our current location at 131 Stover Drive, Carlisle, PA.

Ritner Steel, Inc. has grown through the years with amazing team support and continues to develop increased capacities. We are AISC certified.

Recently (spring 2021) we relocated our office staff to a new office at 81 Stover Drive. Click to view our new office!
