The Groke and SOMMER companies came together in 2004. Groke is a pioneer on the German front door market and sets standards in design, security and ecological energy balance
Groke‘s technical intelligence and innovation have brought us pioneering products such as the invisible swing door operator, the automatic sliding door and the loft doors. The collaboration with SOMMER promises further progress. This success would not have been possible without our loyal customers, suppliers and dedicated workforce.
Managing Partner
Groke Doors Ltd. in Hagenbach can already look back on over 125 years of success in metal construction. The company has made a name for itself above all with pioneering solutions in the field of aluminium construction elements.
Groke products are among the top products for the German building element market and are manufactured in accordance with the strictest in-house standards. Their design and security set standards, as does their ecological energy balance, which is based on outstanding, specially developed, thermally insulated aluminium profile systems. Another milestone is the keyless opening of front doors via fingerprint. Every Groke product makes its way from the factory to the customer in elaborate, secure individual packaging. To ensure that deliveries and promised deadlines are always met exactly, Groke‘s own fleet of vehicles is on the ball and arrives at its destination on time.
The front door is crafted by us according to your personal preferences and fits your house perfectly. Computer-controlled saws, drills, milling machines and punches ensure precisely fitting components, such as the customised frame. But it‘s not just our machines that work precisely and reliably. We owe the quality of Groke doors to our qualified employees, whose skill and manual labour ensure that everything is just right.
We want you to feel comfortable in your own four walls. That's why we put a lot of effort into your front door. What makes a Groke front door better than others is the mix between highly professional machines for aluminum profile processing and individual handwork during production, as well as the specially developed profile systems.
This makes the difference in quality.
Production
Groke front doors are among the top products on the German market. Perfect workmanship, stylish design and safety make our doors what they are. 125 years of experience in metal construction can be seen in the doors. Thanks to our self-developed profile system, a construction depth of 90 mm and material thicknesses of up to 3 mm, the doors are stable and robust. The solid construction gives a high-quality impression.
Many other manufacturers use purchased profile systems.
Not so with Groke: We developed our profile system ourselves and continually optimized it down to the smallest detail.
Thanks to a construction depth of 90 mm and material thicknesses of up to 3 mm, Groke doors are stable and robust. The heavy construction and the safety elements that are already included as standard in the basic equipment offer reassuring protection. A stable connection between the frame and the threshold makes installation easier and ensures that the construction is extremely resilient and long-lasting.
As standard, three all-round sealing levels ensure high wind and weather resistance without interruption. Because only a really tight door protects you from cold and noise.
Sustainability is an integral part of the SOMMER Group’s corporate philosophy. We take responsibility for the environment, our employees, and society – today and in the future.
With a focus on future generations, we continuously work on solutions that combine quality and environmental responsibility. In this way, the SOMMER Group actively contributes to a sustainable future.
