Stone Products Inc. traces its roots back to 1966, when it was founded by Don Sterling and George Carmack to produce aggregate for construction use. The company was initially established to support Beaver Excavating Company — founded by Sterling in 1953 — of which it remains a subsidiary.

For more than 15 years, Stone Products mined and supplied aggregate material for Beaver's growing number of infrastructure projects. When the original stone deposits were eventually depleted, the company shifted gears.

Rather than exit the industry, Stone Products transitioned into specifically the aggregate processing equipment market. Since 1985, the company has focused on supplying, refurbishing and servicing the equipment that drives aggregate production.

Stone Products has steadily grown from a regional operation into a nationally and internationally recognized supplier.

One of the company's core offerings is refurbished equipment that has become a major value driver for customers looking to extend budgets without sacrificing performance. By refurbishing used machinery, Stone Products helps clients achieve substantial cost savings while maintaining high standards of quality and reliability. In addition to refurbished equipment, the company offers equipment sales, parts and responsive service support.

Most recently, Stone Products launched flexible financing options to make it even easier for customers to access the equipment they need. This initiative reflects the company's commitment to evolving with its customers and delivering tailored solutions that fit a variety of operational and financial needs.

Through it all, Stone Products has remained grounded in its founding mission: to provide dependable, long-lasting solutions to the construction and aggregate industries. As a subsidiary of Beaver Excavating, the company benefits from decades of hands-on industry experience and continues to grow by listening to its customers and delivering with integrity.

Whether it's supplying a new plant, rebuilding used machines or offering maintenance support, Stone Products is known for helping producers succeed — just as it has been for nearly six decades.
