Who We Are
Rhin-O-Tuff was formed in 2004 by a group of concrete industry designers, engineers and building contractors with a vision for making power trowels safer and more affordable. The company brings together more than 70 years of experience designing and manufacturing walk-behind power trowels. Using their knowledge of industry needs, Rhin-O-Tuff's team of designers and engineers has created a power trowel that significantly reduces repetitive stress injuries due to its unique vibration dampening system.
At Rhin-O-Tuff our sole focus is on power trowels!
