FB Ketju

What FB Ketju does

FB Ketju (legal name FB Ketjutekniikka Oy) is a Finnish manufacturer of industrial conveyor chains, sprockets, and chain components founded in 1945 and headquartered in Lappi, Rauma. The company produces standard and custom-engineered conveyor chains, lug/link chains, saw chains, roller chains, and split sprockets, all manufactured in-house at a modern 6,000 m² single-roof facility using precision laser cutting, robotic and cobot welding, automated machining, and laser marking. Its core technical differentiator is proprietary materials: FB1000, a registered trademark premium-grade steel developed with Ovako AB and Tampere University, and Zero Steel chains made from SSAB Zero™ fossil-free steel, making FB Ketju the first chain manufacturer worldwide to adopt the latter.

FB Ketju serves enterprise industrial customers across eight primary verticals — biomass/energy, wood processing, paper and pulp, cement, mining, recycling, steel, and fertilizer — with chains designed to withstand abrasion, corrosion, high temperatures, and shock loads in heavy-duty material transport. Named customers include Finnish energy utilities Helen, Keminmaa Energia, and Raasepori Energia, alongside the implicit near-universal penetration of Finnish sawmills, paper mills, and power stations over eight decades.

The business model is project-based B2B sales of customized industrial components with no public pricing and no recurring contract base. Revenue is generated through one-time chain sales and technical services (on-site wear analysis, installation support, maintenance consulting), priced via bespoke quotations. Distribution runs through three channels: a direct domestic sales team in Finland, the seven-company FB Group network across Europe (UK, Germany, Sweden, Austria, Norway, France), and additional worldwide distributors. FB Ketju is privately held by Swedish listed industrial group Addtech AB, which acquired it as part of FB Industri in 2000.
