1, material cutting. The cutting equipment is mainly used for cutting materials. The length of materials should be determined according to the design requirements and with reference to the structural details of doors and windows, and the cutting should be accurate. Generally speaking, the cutting material of sliding doors and windows should adopt right-angle cutting; Flat doors and windows should be cut at an angle of 45; For other types, the cutting method should be selected according to the assembly method.

Step 2 drill holes. The sash assembly of aluminum alloy doors and windows is generally connected by screws, so whether it is the assembly of horizontal and vertical bars or the fixing of accessories, it is necessary to drill holes in the corresponding positions. Before drilling, the profile should be positioned according to the assembly requirements, and the drilling position should be accurate and the aperture should be appropriate. It is not allowed to change the drilling hole on the profile repeatedly, because once the hole is formed, it is difficult to repair it.

Step 3 assemble. According to the requirements of construction details, the profiles are assembled by connecting connectors with screws. There are three assembly methods of aluminum alloy doors and windows: 45 angle butt joint, right angle butt joint and vertical butt joint. Generally, the horizontal bar and vertical bar are connected by special connectors or aluminum angle iron, and then fixed by screws, bolts or aluminum studs.

Aluminium alloy doors and windows

Aluminum alloy doors and windows refer to doors and windows with aluminum alloy extruded profiles as frames, stiles and fans, referred to as aluminum alloy doors and windows for short. Aluminum alloy doors and windows include wood-plastic composite doors and windows with aluminum alloy as the stress bar (the bar bears and transmits self-weight and load), which is called aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows for short.
