International Pipe Group was founded in 1978 by Alfred H. Karchmer. In 1985, his son, Donald, joined the business after graduating from college. Together, they spent the next several decades growing it into one of the nation’s leading steel pipe distributors. Today, as a third-generation family-owned and -operated business, we take our reputation very seriously and always operate with the highest level of integrity. It is our mission to achieve excellence in customer satisfaction each and every day!

At International Pipe Group’s headquarters in Oklahoma City, we operate a 35-acre, full-service facility, which houses our corporate offices, processing center, and state-of-the-art fabrication and coating shop. Our experienced staff and yard crew are always working hard to ensure accurate order processing and prompt customer service.

We supply products to dealers, end users, and contractors for a wide range of applications, including but not limited to general construction, utilities, boring/excavation, infrastructure, and oil and gas. With tens of thousands of tons in stock, customers can believe that we have the steel pipe they need for their next project. For over 45 years, we have remained your one-stop source for new, used, and surplus steel pipe, ranging in diameter from 1/4" to 120", in numerous wall thicknesses, and with various finishes.

We have experienced strategic growth over the years, steadily expanding our footprint through targeted regional acquisitions:

2006: Acquired the assets of KDC Pipe in Rialto, CA, including its Phoenix, AZ office.

2011: Acquired Liberty Rocky Mountain Pipe near Twin Falls, ID, forming Bison Pipe.

2012: Acquired the assets of A.A. Gilbert Pipe & Supply in Shreveport, LA.

2015: Acquired a former MRC Global manufacturing facility near Tulsa, OK.

2019: Acquired P.N. Best & Co. near Seattle, WA, forming Bigfoot Pipe & Piling.

As our network grew, we expanded our offerings to include specialized subsidiaries. In 2024, we acquired R.B. Jacobson, Inc. in Hesperia, CA, creating Big Bear Pipe & Steel to strengthen our West Coast fabrication and distribution capabilities. We also established Red Fox Pipe & Fence as our dedicated Oklahoma fencing base, expanding our inventory of custom steel gates, panels, and agricultural fencing products. Together, these additions enhance our overall reach and enable us to deliver complete steel pipe, piling, fencing, and fabrication solutions nationwide.
