To produce sandwich panels Alutech uses the galvanized steel tape 0,4 mm thick. It guarantees good reliability properties and durability of the door leaf.
The zinc coating 16 μm thick, as well as two-layer polymer coating 25 – 35 μm thick reliably protects the sandwich-panels surface against mechanical damage and precipitation exposure.
The front side of Alutech panel is covered with polyurethane coating modified by polyamide particles (PUR-PA). This coating:
The garage doors include components with excellent anticorrosion properties thus extending the life cycle of the doors:
Tests performed in the independent accredited laboratory, Republican Unitary Enterprise BelNIIS Institute (Minsk), proved that elements of Alutech door leaf withstood the exposure of salt fog for 750 hours. This corresponds approximately to 15 years of doors operation in coastal regions and such cities as Saint-Petersburg, Makhachkala, Murmansk, Arkhangelsk, Vladivostok, Magadan, Okhotsk, Novorossiysk, Sochi, etc.
