Thermal-Flex railroad switch heating products were initially developed more than 30 years ago evolving out of our effort in research, development and the manufacturing of stress relieving equipment, one of our first industrial heating product lines. Our stress relieving equipment was widely used for relieving the internal stresses created in massive steel parts such as pipes, valves, and boilers, caused by the heat of welding.
Today, our railroad switch heating products incorporate some of the same materials and design techniques we utilized to develop our stress relieving equipment. From our first designs and continued product development, Thermal-Flex Systems is able to offer a broad range of railroad switch heating products, including the only flexible rail heating element in the industry.
Over the years, thousands of our switch heating systems and products have been manufactured and delivered to U.S., Canadian and European railroads. Designed to withstand the wear and tear of repeated use in harsh environments, our products are used throughout the world by railroads, transit companies, major power facilities, engineering and construction firms, the U.S. Navy and many other manufacturing and service companies.
