ALT C43 Door

ALT С43 is a system of non-insulated profiles for the construction of elegant and affordable aluminium doors. This is an optimal solution for application in administrative, commercial, manufacturing and residential facilities in warm climate but it can also be used as an interior partitioning, winter garden system as well as entrances without high-energy efficiency requirements.

ALT C43 system offers a very cost-efficient inward and outward opening door solution due to its optimized fabrication process. ALT C43 system enables manufacturing of structures for external and internal doors, entry groups in any administrative and public buildings and premises (shops, hypermarkets, business centers, offices, trade pavilions, gas filling stations, airports and railway stations, bus stations and etc.)

ALT C43 aluminum profile system was designed to be used for both internal and external glazing, without any special requirements for thermal insulation.

ALUTECH ALT C43 system is designed so that bottom parts of the dumb and swing leafs look exactly the same. It is very important for visual perception and construction proportions maintenance.

Plastic fastening elements allow you to easily replace door threshold.

Different infill units can be used in ALUTECH ALT C43 system, such as glass, insulated glass units or sandwich panels with thickness from 4 to 24 mm. Infill units are installed on special bearing plates in accordance with installation scheme. The same bearing plate is installed into dumb parts of the structure, leafs and sashes.
