Product Range

As each FB subsidiary focuses on a particular niche product, the group as a whole is able to offer customers highly specialized chain and associated parts for a wide range of different industries and applications. Customers are able to order their required chain (including conveyor chain, roller chain, sawmill, sharp top chain or leaf chain) from their local FB branch which will then be shipped from the factory where it is produced. 

The Conveyor Chain Specialist

From its advanced production facility in Köyliö, Finland, FB Ketju manufactures conveyor chains, sprockets and attachments for wide range of different industries, often according to clients’ individual requirements. FB Ketju is well-known for providing exceptional quality and service and aims to work closely with clients’ design, engineering, procurement and scheduling departments to provide solutions for all their conveyor chain needs.

FB Ketju has always invested heavily in quality and reliability. As a result of this determination FB Ketju in 1993 became the first chain manufacturer in Scandinavia to be fully accredited to ISO9000 certification. The consistent high quality is an advantage for the customer – a durable, reliable conveyor chain is a profitable investment.

FB Ketju uses high quality raw materials which can be recycled. Production machining chips and other waste steel is collected and recycled. The chains are lubricated with an environmental friendly special conveyor chain lubricant. All packing is totally made of recyclable materials. As an acknowledgement for the continuous work for environment, FB Ketju accredited to ISO14001 certificate in 2002.


Our history dates all the way back to the 1870s when Adolf Fredrik Hedengran established a factory in central Eskilstuna, Sweden for the manufacture of iron and steel products. In 1908 the company was purchased by the newly formed Eskilstuna Fabriks AB. Working under this name it manufactured conveyors chains for the first time in 1912. 

Manufacturing of conveyor chains first started in Finland under the name Ammus Oy but subsequently the company operated under a number of different owners with differing names. In 1979 production in Finland moved to a purpose build factory in Köyliö, Finland. In 1985 the factory in Finland was purchased by the FB Group from Huhtamaki

FB continued manufacturing conveyor chain in both Sweden and Finland until the late 1990s when production of all conveyor chain was eventually consolidated into the much improved and modernized factory in Köyliö, Finland.
