KWH Group Ltd – A family-owned growth company

The history of the KWH Group dates back more than 90 years

The KWH Group has its roots in the timber trade in the 1920s and 1930s. Investments were subsequently made in fur animal breeding as well as plastic products such as expanded polystyrene, floor tiles, plastic pipes and plastic film. In the following decades, investments were made in what forms the basis of today´s booming business; logistics in the 1950s, abrasives in the 1960s and water traps in the 1980s.

Over the years, we have invested in companies in attractive new markets and industries, and have also divested companies along the way. The KWH Group and its predecessors have never been afraid to renew. Our ability to constantly seize new opportunities and create customer value has meant that the KWH Group has developed over time into a diversified, international industrial group and service provider in the logistics industry. Diversity and courage to innovate have also helped us through the year 2020 marked by the corona pandemic.

The KWH Group today is a family company with strong roots in Ostrobothnia. Our industrial knowledge, our networks and our financial strength give us a solid foundation on which to build for the future.
