The reason why we are doing what we are doing is because we want a better life. For our customers, our colleagues and of course for ourselves.
The STA Story
No boundaries. Only Opportunities.
STA primarily develops and produces hardware for most world-leading aluminium window & door brands. We have a sterling reputation for our quality, reliability, speed and smart solutions.

But we're a lot more than that.

We believe that the key to a better life is in our hands but is not always easy. We believe that working together, however, makes it easier to take care of each other. We are agile – in our job and in our lives. Working together motivates us to work harder, smarter, more creative, safer, more efficient, and more knowledgeable. Our dedication to this has no boundaries...
Aluminum Components
We develop and produce aluminium components for most of the world's leading door and window brands. Chances are that if you've opened an aluminium door or window somewhere in Europe today, you've interacted with a product from our factory. We also design and manufacture aluminium components for the automotive industry, bicycles and other industrial and household products. We are a true one-stop-shop, from the design, engineering, and development of systems and components, through mold-making and casting, to finishing and packing- ready for distribution around the world.  

If your product idea needs to be functional, beautiful, competitively priced, and last a lifetime, we can make it happen.
