Started in 1949 by two innovative, tinkering brothers named Lynn and Russ (LR). These brothers had lived through the Great Depression and World War II and throughout their lives had developed a driving curiosity about how things worked. So they combined their experience and started Marco Products which focused on building unique products for local industrial customers. This new found adventure enabled them to tinker and also support thier young, growing families. Marco Products eventually became Lynrus Corporation when they brought on investors in the late 1960’s then at the turn of the century became Lynrus Aluminum Products when Russ Margetts, Russ Senior’s son, took over operations of the business.

After nearly 20 years of exciting growth and new opportunities, Russ sold the company to his son Tyler who is the current owner. In the transition of ownership the company started anew as LR Dynamics, Inc. LR hails back to the original founders Lynn and Russ and “Dynamics” represents forward motion and positive change that is the goal of the third generation of family owners.
