Mobility and safety for the highest demands

With a great deal of experience, expertise and ideas, we support technological progress and turn challenges into solutions. The resulting creation of new and improved springs and bent parts puts new options for optimising products into the hands of engineers and designers. This allows GRUEBER customers to impress their end customers and get them excited about their products over the long term.

Quality since 1828

For almost 200 years, iron has been forged and formed into high-quality products in the GRUEBER factory workshops. And the whole time, we have continuously worked on further developments in close cooperation with our customers. In the meantime, we have become a leading international partner for solutions in the development and production of springs and bent parts for a wide variety of applications and industries.

Today, instead of using a hammer and anvil, our production takes place with highly advanced, state-of-the-art machinery as well as with experienced, highly skilled and committed employees who breathe life into our unique quality standards.

GRUEBER currently has almost 200 years of experience in metal processing and spring production. With 180 employees, we produce approx. 10,000 tonnes of steel springs and bent parts yearly at the Hagen location.

There are GRUEBER springs and bent parts for a wide variety of applications and in a broad range of sizes – with rod diameters up to 65 mm and unit weights up to 200 kg.
