specialized in springs.

Empowering You

Driven by mega-trends such as globalisation and digitalisation, the world is changing at a rapid pace. This has an immense effect on our customers’ markets and products. As we see it, our job is to provide and implement the right responses to the increasing demands of the market.

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. That’s what we at GRUEBER mean by Empowering You.

Empowering customers since 1828

For over 180 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.
