Aluminum – lightweight, durable, corrosion resistant, easy to clean construction material, long-life, environmentally friendly, does not contain impurities of heavy metals, does not emit harmful substances under the influence ultraviolet rays and keep working in all weather conditions when temperature changes from -80 0 C and up to 100 0C. Aluminum is better than other material retains its structural properties with temperature changes. After the surface treatment of aluminum products, they become resistant to the harmful effects caused by rain, snow, and smog. One of the drawbacks of aluminum is that the direct contact of aluminum with other metals can cause leakage of electrolytic reactions, which leads in turn to a strong aluminum, until its destruction. To date, the technology was perfected production of aluminum – the main material for making light and thin structures, which possess the same strength and durability as traditional structural building materials.

Aluminium profile, usually made of three-Alloy: aluminum, magnesium, silicon. Aluminium has high thermal conductivity, so all the leading manufacturers produce two types of profiles that differ in scope: "cold" profile, with high thermal conductivity, without a thermometer insert. Suitable for doors (both internal and external) in unheated buildings or for manufacturing Interior doors in heated rooms, "warm" profile combined with low thermal conductivity, having a heat-insulating box. Intended for the manufacture of exterior doors in heated buildings.
