Laboratory Capabilities

Modulus of Rupture

R&R maintains the largest, most advanced product application and development laboratory, research foundry and technical staff for benefit of the industry.


With unique testing equipment, we are the only industry supplier able to look at shell strength and flexibility properties in real-time and at temperature.


These resources are used to develop new products, analyze material performance and service customer needs.
