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.
