The company

A strong partner for over 25 years

Karl Heinz Fastner, former managing director of the company, laid the foundation stone for Fastner Leichtmetalltechnik when the company was founded in 1992.

We are a competent system supplier specializing in the production of sophisticated and complex prefabricated components made of aluminum and other light metals.

Our aim is to find the best technical and economic solution for each project in close cooperation with our customers. To achieve this, we rely on a highly motivated team, state-of-the-art production facilities and a well-developed quality assurance system.


Corporate development

Even a few years after its foundation, the business model of Saint Jean Industries Stuttgart is still successful – through sustainable and healthy growth.

The expansion of the company, inaugurated in 2006, enabled us to significantly increase our manufacturing and logistics capacities – with an impact on sales and the number of employees.

In 2016, the ownership structure of Fastner GmbH changed. The shares became 100% owned by the Saint Jean Industries Group from France.
