Straight-line classical design of system profiles allows manufacturing structures in a modern style;
Configuration of ALT C48 system profiles ensures preserving the same visual proportions of the profiles in the swinging, sliding and blind parts of the structures;
The width of profiles’ imposts and frames is provided in three standards sizes: 26 mm, 36 mm and 50 mm. This enables saving the materials and perfectly matching profiles by the design of constructions of various sizes and filling types;
Primary system profiles (frames, imposts, foot stalls, leaves, compensating profiles) have the same coupling sizes for corner leveling angle. In its turn it reduces the range of required additional components, eliminates displacement of connected profiles’ planes, enhances the strength of connections and improves the appearance of structures;
Plastic plugs installed in door structures eliminate through slot blowout and make the structure more attractive.
Reliability and stability
Perfectly matched ratio of geometrical and strength properties (AlMg0.7Si 6063 Т6 alloy in compliance with GOST 22233-2001) of the system profiles ensures sound operation of the structures for a long period of time;
Manufacture of large and complex structures is done via connecting several separate structures with each other using coupling and reinforcing profiles;
Special reinforcing profile is designed to be installed in primary profile chambers in fixation points of door closer and automatic drive slide.
Angular embedded components provide two possibilities to connect the structure angles:
By pressing in the connected profiles on a pressing machine;
By fastening angles with pins, which does not require the automotive pressing.
Original configuration of the frame and impost profiles provide two variants of fixation:
Using aluminum embedded components with their fixing in the profile’s plane by pins or self-tapping screws;
Using self-tapping screws in the impost profile. This is a more efficient connection, it does not require the use of embedded parts, enables fastening of impost profiles at an angle.
Easy to process and assemble
Simple attachment fitting of thresholds enables quick and easy assembly. In the course of the door structure operation, if damaged or worn, the threshold profile can be easily replaced without dismantling the entire structure. There are two standard types of threshold: large and small – for new construction and reconstructed buildings;
Unique additional profiles and component parts for central solutions of bottom junction of door wings to the threshold/floor do not require additional milling operations. These profiles provide easy and convenient assembly, they are cut at 90°;
A general-purpose support plate designed for frame and wing profiles reduces the range of component parts;
The developed configuration of window leaf enables using one standard size of glass stop profile in the blind and swinging part, thus almost completely excluding any errors during the calculation of structures and order of materials.
