PRT’s rugged tie platform achieves the highest levels of structural integrity, safety and performance. The composite tie design employs a patent-pending cavity pattern that provides up to four-times the lateral stability of a standard wood tie. The cavities remove material from the tie in areas where combined stress levels are low, similar to structural I-beams. Additionally, the cavities bolster interaction with the ballast with deep ribs that span across the bottom surface of the ties.

The company supports a research and development team comprised of professional engineers and polymer scientists that rigorously investigate areas for improvement. Through this supported effort, PRT has revolutionized composite rail tie design and will continue to integrate a highly technical component to remain on the cutting edge of the industry.

PRT has proceeded in a meticulous manner to develop, locate, and secure a superior tie design and a reliable high-volume manufacturing process. This foundation is fortified with a strong commitment to maintain quality on a consistent basis.
