The JECO-Jellinghaus factory in Gevelsberg was part of the long industrial tradition of the Ennepe-Ruhr region in western Germany. The company traces its origins back to the late 19th century, when Julius Jellinghaus founded a metalworking business around 1885. Over the following decades the company developed into a manufacturer of forged and machined metal components used in mechanical engineering and industrial applications.

As the company expanded, a larger industrial complex was built in Gevelsberg consisting of production halls, forging workshops, storage buildings, and administrative offices. For many years the factory provided employment for a significant number of workers and formed part of the local industrial economy that characterized the region.

In the 20th century the company became known under the name JECO-Jellinghaus, continuing the long tradition of metal processing in the area. However, like many medium-sized industrial companies in the Ruhr region, it eventually faced increasing economic pressure due to global competition and changes in manufacturing.

In 2015 the factory finally closed, ending more than 125 years of production. Around 160 employees were affected by the shutdown. After the closure the site stood largely unused for some time before redevelopment plans were made for the area.
