Many modern entrance doors need a power supply in the door leaf for electronic
door locks, fingerprint scanners and other access systems or integrated lighting.
In cooperation with SOMMER, Groke has developed a new system for the power
supply of doors. This first of its kind comes without complex cabling or spring
contacts that would be susceptible to wear, with power being supplied via the
These are the two main reasons why Groke uses only powder coat finishes for its aluminum entry doors.

Groke uses aluminum to build their modern entry doors.
Why Aluminum? Because it is so much more than just cans and foil.
Today aluminum is one of the most popular materials in use. Aluminum’s unique properties are the key to its versatility.
Aluminum is the most common metal found in the earth’s crust (approximately 8%) and is the third most plentiful element known to mankind. Only oxygen and silicon (sand) exist in greater quantities. It wasn’t until 1808 that British electrochemist Sir Humphrey Davy established the existence of aluminum and not until Danish scientist Hans Christian Oersted produced the first tiny pellet of the metal 17 years later. It took many years of experimentation before a process was developed for aluminum production. The first production companies were not established until 1888 (one each in the US, France, and Switzerland). Through the early 1900s with this new process the price of aluminum continued to reduce as the demand continued to rise.
By the end of World War II the stage was set for aluminum to become the most widely used non-ferrous metal in the world.
Doors are often the “weak link” in modern, high performance buildings, but they don’t have to be. Our standard multi-point locking, combined with multiple levels of uninterrupted gaskets offers a very tight seal that keeps your valuable and comfortable conditioned air inside, where it belongs.
Whether your goal is Passive House certification, Net Zero, LEED Platinum or another green building standard, we applaud your efforts we’re excited to help you achieve your goals.
If you’re just looking for a really great door that offers more comfort, style, energy savings, and peace of mind… we’ve got you covered too!
All Groke Doors are designed around three basic criteria; Style, Efficiency, and Security.
Every step in the manufacturing process strives to reach the highest possible level for each of these. Groke uses the latest CMC technology to create our computer generated styling and true German craftsmanship to assemble a product that meets our highest quality controls.
This is what separates Groke from every other door:
One of the many wonderful things about Groke custom aluminum doors is the fact that they are all truly custom made for your home or building application so your door is the perfect fit and specification. Many of our customers love the fact that we can build very wide entry doors… up to 45.5 inches wide usable opening width for single doors(51 inches wide to the outside edges of the jamb).
Depending on architectural constraints, having the ability to specify your rough opening width is a great opportunity to go wide! There are many benefits to having a wide door such as increased accessibility for wheelchairs or baby strollers, greater convenience when moving furniture in or out, or simply to make an impressive visual or aesthetic impression. Having a wide, beautiful custom door is easy with Groke!
“Custom” is a word you will hear a lot when looking for doors and the term can mean a few different things. In reality, there are different levels of customization available from different manufacturers, and some doors are certainly more custom than others. Often times, the need for a custom door is driven by the fact that the application requires an unusual size.
Let’s explore the sizing issue a little deeper.
