About National Flooring Equipment

Our company was founded in 1968 when the Anderson family began developing new flooring tools in their garage in Minnesota. From there, they started designing surface preparation equipment with a focus on durability and long-lasting performance. The Olson family bought National in 2007, shifting the company’s primary focus to industrial-grade surface preparation and floor removal equipment, with a focus on customer service. The Olsons built upon the Andersons’ tradition of quality products and competitive pricing.
Over time, they introduced larger floor removal equipment to the market, expanding their operations, reputation, and customer base. Thanks to their vision, National now has over 50 patents registered in the United States and around the world, giving us a global presence unmatched in our industry. We’re incredibly proud of the level of customer service everyone at National provides. It’s not unheard of for a National representative to personally deliver a piece of equipment when a contractor needs it quickly to complete a project. We’re here for our customers seven days per week, ready to solve problems with tools that make their job easier.

Proudly Built in America

Our products are made right here in the United States, where quality assurance standards are among the highest in the world. When you buy domestically, you benefit from accessible facilities, more reliable supply chains, and superior products. We’re also there for our global customers with local service teams ready to lend a hand when required.

We're proud to build locally, ship globally, and help you solve problems no matter where you're located. This approach is how we built our company, and it will always be part of how we do business.
