Why are the system doors and windows so slow?
The system door and window profiles are produced by designated profile manufacturers, and the processing standard strength and thickness are higher, which requires higher processing accuracy. Its spraying process, tensile strength, conditional yield strength and other indicators are far superior to ordinary aluminum profiles for doors and windows.
The wall thickness of system doors and windows is generally above 1.6mm, which is much thicker than that of non-system doors and windows. The linear density is increased by about 20% compared with ordinary aluminum alloy doors and windows, and the cost of pure materials is increased by about 30% as a whole. According to the above differences, the cost caused by profile differences is 30%-40% higher than that of ordinary doors and windows.
Difference between system doors and windows and ordinary broken-bridge aluminum doors and windows
1. Differences in manufacturing processes
The system doors and windows are superior to the broken bridge aluminum doors and windows in manufacturing technology. Ordinary broken-bridge aluminum doors and windows adopt the angle collision process, and the aluminum alloy angle code is inserted into the 45-degree cut profile. Aluminum alloy doors and windows form a Chinese style in the corner bumping process as a whole, and no glue is needed. System doors and windows, whether window frames or window sashes, should be glued.
2. Differences between installation methods
The installation method of doors and windows of the system is to install with adhesive tape on site, that is, after the glass installation is completed, add a layer of glass glue on the glass frame. Damaged aluminum doors and windows are sealed with neutral silicone weather-resistant adhesive during installation. There is no difference between the two installation methods, but the system doors and windows installed with tape on site can balance the indoor and outdoor pressure better.
3. There are different requirements for glass.
System doors and windows have high requirements for glass, so tempered glass must be used; Broken bridge aluminum doors and windows do not require much glass, such as laminated glass.
