The RDI Group traces its roots to 1902, when machinist Fred Drews and inventor Hugo Reichel founded Reichel & Drews in Chicago. What began as a small manufacturing company grew through a commitment to practical engineering and a determination to help customers solve complex production challenges.
More than a century later, that commitment remains unchanged. New technologies and evolving markets have shaped the business over the years, but the focus has always been the same: delivering reliable industrial solutions that help customers improve performance and grow with confidence.
For over a hundred years, customers have relied on our companies to deliver practical solutions backed by technical expertise and responsive support.
That trust continues to guide how we serve customers, invest in our businesses, and build partnerships for the future.
For more than 120 years, Reichel & Drews has helped shape the roofing industry through innovations that improve manufacturing performance. Today, the company designs and manufactures production equipment for asphalt shingle and waterproofing membrane manufacturers worldwide. Customers also rely on Reichel & Drews for controls, replacement parts, field service, and engineering support.
RDI Enclosures designs and manufactures prefabricated electrical buildings, equipment shelters, and integrated enclosure systems. Its solutions protect critical infrastructure and industrial equipment in some of the industry’s most demanding environments. Customers depend on RDI Enclosures for durable, configurable designs built to support long-term performance.
While each company serves a distinct market, both benefit from the resources and experience of The RDI Group. Shared manufacturing capabilities, operational support, and leadership allow each business to remain focused on its customers while continuing to invest in growth and innovation.
Our headquarters and manufacturing facility in Itasca, Illinois brings together engineering, manufacturing, and customer support under one roof. This collaboration helps us respond to changing customer needs while maintaining the quality and reliability that have defined our businesses for generations.
Innovation has been part of our story since the beginning. Early patents and manufacturing breakthroughs helped shape modern roofing production. Today, that same spirit of innovation continues through advanced production equipment, engineered enclosure solutions, and ongoing investment in new technologies.
The industries we serve may evolve, but our approach remains the same. We listen carefully, solve practical problems, and build solutions designed to deliver value for years to come.
