How everything started...

When musician Paulus Sajakorpi returned from the war, he continued his career by playing dance music in various restaurants. As times were gloomy and the income level of musicians was modest, he established a small company with his brothers in 1945, whose main business was to produce brushes, among other things, for the construction industry, something which moved along at full speed.



In 1955, the ever-inventive Paulus developed the Piassava Street Broom which, due to its superiority, soon replaced the birch twig broom throughout Finland. A patent was applied for the invention. Sajakorpi Oy had a dominant market share in broom production for fifteen years. In 1975 the production of these brooms was ended. The same broom model is still used in Finland, produced by other brush manufacturers.



While other Finnish brush factories were developing the production of their household brooms and brushes, in 1960 Sajakorpi Oy was heading towards the design and production of technical brushes. The first important sectors were brushes for car wash machines and brush rolls made of horsetail hair used in paperboard smoothing.



The son of Paulus, the engineer Kimmo Sajakorpi, began working in Sajakorpi Oy as a technical manager in 1973.


In this period all street sweeping machine brushes were being imported, so the company decided to produce these. In order to increase competitiveness, the  production process was further improved. It obtained a patent. In fact, the domestic market was taken over in a few years.


The second successful product improvement project was the development of plastic coating for ski jumping hills. The project was undertaken after the receipt of a request from the Finnish Ski Association. The plastic coating was marketed in partnership with Pertti Spede Pasanen, a company which had developed a jumping catapult.


Paulus Henrik Sajakorpi completed his life’s work in 1976.



As plastic brush fibres were imported goods and their quantities had grown, Sajakorpi Oy started to produce its own polypropylene fibre in 1983. In addition to this, the export of brushes for sweeping equipment in the Nordic Countries began at the end of the decade.




Sajakorpi Oy developed the Saja Safety™ hill element, obtaining a worldwide patent for it. Thanks to this a market share of 60% was achieved in ski jumping hill plastic coating. Several dozen plastic coatings for ski jumping hills were manufactured for the USA, Canada, and Japan. Along with its patents, this process was sold to C E Lindgren Oy in Porvoo in 1995.


In 1996 Sajakorpi Oy announced its brush ring made of 100% polypropylene. The environmentally friendly and recyclable brush ring proved to be more economic and even technically better than traditional brush rings. The new generation of brush rings has been implemented in very many brush machines as genuine replacement parts in Finland, Sweden and Germany.



In order to satisfy the continuously growing export markets, the affiliate companies AS Sajakorpi in Estonia and Saja GmbH in Germany were established. Side by side with the company’s environmentally friendly brush rings, the ECOLINE™ product family was developed. It includes, among other things, the TURBOLINE® side brushes and the SKYLINE™ brush cassettes for cleaning airport runways. So far, exports have reached 32 countries.



In 2005 Kimmo Sajakorpi received the Technical Creativity Award from the city of Tampere. In addition, in 2005 Tampere’s Junior Chamber of Commerce awarded Sajakorpi Oy with the Productive Idea honourable mention.
The family group reached the age of sixty years.



Technical student Aku-Paulus Sajakorpi, the son of Kimmo, began as an executive director of the parent company, Suomen Tekniset Harjat Oy, in 2006 after having worked in the group for several years along with completing his studies.


In 2007 Tampere’s Junior Chamber of Commerce granted the Environmental Award to Sajakorpi Oy.




Today, the Sajas Group is a 65 year-old manufacturer of technical brushes, acknowledged and recognised throughout the business, whose products are being used in all over the world. The company has remained a completely independent Finnish family concern that is now operating under the aegis of a third generation.

Its success has always been the result of understanding the needs of its clients, high quality product development, and good quality products. Particularly difficult weather conditions have helped us to develop high quality products that are acknowledged all over the world.

Kimmo’s daughter, M.Ed. Anna-Pauliina Sajakorpi, entered the family business in 2010.
