A success story spanning more than six decades

Purso’s story began in 1959 when chemical engineer Esko Ollila realised that there were no Finnish companies anodising long aluminium pieces. Anodising as a process and aluminium as a material were familiar to Ollila from clockfaces and pot lids, but the pioneer-in-the-making also saw the wider potential of the versatile material.

Esko Ollila concluded that there was a demand to be met and established an aluminium surface treatment facility in Siuro to conquer the market with no more than five employees. Soon, the operations were expanded to encompass aluminium extrusion, and the first extrusion line was commissioned in 1974.

Growth through solid expertise

Much has happened over the course of 60 years in the business. Purso currently employs nearly 300 professionals, and the internationally successful company’s output is present everywhere from the facades of important buildings to lighting arrangements.

Despite the necessity of taking risks, Purso has successfully weathered every storm over the years. The company has reached its position as a trusted partner and pioneer in the field through solid expertise and bold action: Purso’s philosophy is rooted in scientific precision and the core values of all family-owned companies – openness, collaboration and responsibility.
