Piristeel

What Piristeel does

Piristeel Oy is a Finnish manufacturer of Pisko-branded rainwater systems, ladders, and roof safety products, headquartered in a single 18,000 square meter factory in Kauhava. The company produces a coordinated product family spanning round and K-style gutter systems (125-180 mm), SafeGrip wall and roof ladders, SafeLine wire-based fall-arrest systems, MultiFast and UniSeam fastening solutions, SnowDefence snow guards (including a variant designed for solar roofs), Pisko Solar panel brackets, balcony fire hatches with a patented telescopic ladder, and raw gutter and sheet coils sold to other metalworkers. Core technology is sheet-metal forming of hot-dip galvanized structural steel finished with SSAB GreenCoat RWS Pural and the bio-based GreenCoat RWS Pural BT coatings; key product differentiators include the patented SafeGrip rung-punching process, certified complete-system anchoring, and CE/P-mark compliance on safety-critical items.

Piristeel generates revenue through three streams: finished Pisko goods sold to end consumers and trade buyers via a nationwide authorized retailer network and an owned e-commerce webstore; raw coils sold directly to metalworking businesses, roofing contractors, and manufacturers from the Kauhava warehouse; and professional services including technical documentation, installer support, and authorized annual safety inspections. Pricing is not publicly disclosed and is negotiated through dealers or processed via the webstore. The company has operated since 1974 and joined Ruukki Construction, part of the SSAB Group, in spring 2019, consolidating three prior sites into the current Kauhava facility. It employs approximately 100 people, holds ISO 9001:2015 and ISO 14001:2015 certifications, and is described as the market leader in Finland for its product categories, with export activity supported through SSAB channels.
