Overview

Piristeel Oy is a Finnish metal industry company based in Kauhava, Finland, specializing in roof accessories, rainwater systems, ladders, and roof safety products. The company was founded in 1974 in Kivijärvi by Pentti Piri, initially producing simple metal products such as clothes drying racks and ladders, and operating as a travelling merchant. During the 1980s, as production became more efficient and the company grew, it moved to larger premises in Lapua, closer to its market. The company survived the economic depression of the 1990s through flexibility, perseverance, and cooperation with its staff. In the 2000s, Piristeel grew steadily by investing in people, production equipment, and facilities. In 2018, the company, then known as a Lapua-based business, relocated its production facilities to the former Finn-Power premises in Kauhava. In February 2019, Ruukki Construction, a subsidiary of SSAB, acquired a 67% majority stake in Piristeel. In 2019, Piristeel also consolidated all its operations from three separate locations into one facility in Kauhava. Today, the company employs approximately 100 people, and its factory, described as Europe's most modern roof safety factory, covers 18,000 square meters. In 2018, Piristeel's turnover was 20 million euros, and it was the market leader in its field in Finland. The company's product family includes Pisko SafeLine cable systems, Pisko MultiFast fastening solutions, rainwater systems, ladder products, snow guards, roof bridges, roof safety equipment, gutter rails and sheet metal coils, Pisko Solar, and fire hatches. Piristeel became part of Ruukki Construction in spring 2019.
