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.\u003c\/div\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\u003cspan\u003eOver 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.
