Modern and timeless front doors
Groke produces high-quality modern front doors. A broad range of individualisation options allows us to customise them to suit your requirements.
Timeless
Timeless describes not only the design of our front doors, but also their durability. Through a combination of reliable technology and high-quality materials which have proved their worth over many years, we manufacture doors which meet all your requirements.
Modern
The word modern refers not only to the technology which ensures your personal safety inside the door, but also describes its understated, attractive design. Our doors complement the entrance to your home through the use of clear shapes and elements.
Design
Our front doors combine clear lines with cutting-edge technology. And this combination of high aesthetic standards and specially developed functionality is the focus during the design and manufacturing process.

Model Monolith
The Monolith door model has a covering of rock fleece made from a thin natural stone veneer on fibreglass carrier material. For high resistance to the elements, the surface has also been treated with polyester resin. The rock fleece is sealed with a 2K coating, giving the door additional durability. The coating impregnates it and offers protection against climatic influences such as UV radiation and moisture. An additional feature is power supply via the door hinge, replacing the cable junction. Energy is transferred via spring contacts which close the circuit when they touch the axle pin on the frame and the leaf side.
