The ETERNAL line is an absolutely unique choice among external doors. These aluminium doors designed with the use of natural stone are a remarkable element of the building’s elevation. The ETERNAL line encompasses 8 basic door patterns available in 4 RAL palette colours. The ETERNAL line was designed with the use of 6 different types of natural slate rock. Just like in the BALANCE line, the natural origin of the stone gives each door a unique appearance. At the same time they provide 100% resistance to the varying atmospheric conditions of the temperate zone.
