ALUMINIUM PROFILE SYSTEM Russian patent published in 2021 - IPC E06B3/76 

FIELD: building.

SUBSTANCE: present invention relates to the area of building, namely to structures made of profiles, particularly aluminium profiles, for assembling doors for residential and industrial premises. The technical objective is achieved by the aluminium profile system including at least one aluminium profile made in form of a hollow figure or corner or a P-shaped or T-shaped figure and provided with a groove and/or a protrusion on at least one inner or outer side of the wall and at least for connection one insert made of a composite material with low thermal conductivity, wherein the profile is configured to connect with another profile by grooves and/or protrusions, to accommodate seals in the groove of the profile and to place at least one of the profiles in mirrored position. The installed locking apparatus therein is made profile, sunk, sunk with a plate, with increased breach resistance.

EFFECT: technical result achieved by the proposed invention is increased corrosion resistance of the structure of the door made from such system at high humidity, ensured high thermal insulation properties thereof, possibility of using any types of locks in the door structure, including locks with increased breach resistance, ensured low labour intensity of assembly.
