Stress-Cast has a rich family history that dates back to the late 1960s when Ernest Markle, the father of the current President, Jim (James) Markle, was invited to join the company’s board. Soon after, Ernest took over the business, and the Markle family relocated to Salina as Jim was starting high school, due to his father’s new job. Jim and his siblings grew up immersed in the business, with Jim and his brothers working at Stress-Cast during their high school summers. Following his father’s belief that practical experience was more valuable than college, Jim began working at Stress-Cast immediately after graduating from high school.

In 1980, Jim and his brother, Dave, left to establish their own company, Tulsa Dynaspan, but Jim returned to Stress-Cast in Assaria in 1988. During the mid-to-early 1980s, Stress-Cast expanded by acquiring Dynamold, originally located in Salina, KS, and subsequently moved next door to Stress-Cast. Both Ernest and Jim were active members of the PCI Hollow Core Slab Producers Committee, contributing significantly to the industry.

Ernest retired from Stress-Cast in 2005 but continued his work at Dynamold until his passing on January 18, 2007. The tradition of family involvement continues, with Jim’s son and son-in-law now working at Stress-Cast, making it a three-generation family business dedicated to excellence in their field.



One of the significant benefits Stress-Cast offers is its wet cast system, which provides a smoother surface finish than many competitors. The company also produces hollow core products in various dimensions, including 6, 8, and 10-inch thicknesses with widths of 4 or 8 feet.

Stress-Cast’s commitment to quality and innovation, along with its strong family legacy and dedicated workforce, makes it a leader in its industry.
