About us
Achim Steinhilber Metallbau - Schlosserei is a family business in Mössingen-Belsen (Baden-Württemberg) that has existed since 1905 and is run in the fourth generation by Achim Steinhilber. Its portfolio of services includes custom-made aluminium elements such as windows, doors, facades, roof glazing and conservatories as well as steel construction and locksmith work: gates, grilles, railings, staircases, carports, canopies, roofed structures, balconies and gate/fence systems in steel or stainless steel. A special field is the repair and restoration of defective aluminium elements, including the reproduction of parts that are no longer available and the conversion of doors into escape doors. For projects, in-house 2D and 3D CAD drawings are created; the components are sawn and manufactured in the company's own workshop, and installation is carried out on site. The company also manufactures custom products such as climbing plant articles, privacy screen elements and light columns made of galvanised steel. For over 55 years, the company has been manufacturing aluminium products from the firm Schüco.
