Notes about Installation of Aluminum Windows and Doors

Engineering design must calculate and test the strength design
The standard atlas is just lattice drawing of a series of industrial aluminum profiles type and does not indicate the load the specific profiles can bear. So it can’t be used as the basis for acceptance, production and installation. The different series of Aluminum alloy doors and windows profiles must be checked or tested according to the principle of the most unfavorable state of the force.
Because the intensity and stiffness of landing doors and windows are generally inadequate, the main stress column should make a strengthen treatment.
Hardware accessories selection is one of the important factors
Aluminum windows and doors profiles must meet the requirements of GB / T5237-2400 "aluminum building profiles".
Hardware accessories selection and configuration is one of the important factors to ensure the quality of doors and windows. Even the a good quantum window type must also rely on high-quality accessories and configuration.
Pulleys for sliding doors and windows, anti-off sealing device and lower sealing block are important accessories to ensure the quality of sliding doors and windows. We should use the roller nylon wheel. A It is recommended to use durable ABS plastic and EPDM rubber. The lower sealing block work as the sealing function between hook and glide slope. It can effectively prevent the occur of splashing under fluctuations load. It is vital to use EPDM rubber. Wool top is the sealing element between casement and window frame, which determines the quality of air tightness of doors and windows. 
hinges are important accessories to ensure the quality

Hinge bearing capacity is related to the safety of windows and doors and key to shut it smoothly. Hinge bearing capacity is stronger than the friction hinge, so the hinge can be made by the larger grid sash while friction hinges only apply to the sub-grid smaller windows or hanging on the window. Handle is important accessory concerning the safety of door and window as well as sealing performance. General handle is only applicable to the small sash like sub-grid and load. The validity of original pvc adhesive tape lasts about 5 years. 
aluminum windows and doors profiles should be carried out
Processing production of aluminum windows and doors profiles should be carried out in the factory, but not in the construction site.
Processing drainage hole on the sideway of sliding window should follow the principle of the inner fan with outer hole or outer fan with inner hole, to ensure the sealing performance of doors and windows, especially the sliding window above the bottom rail on horizontal orientation.
Before assemble Aluminum windows and doors profiles, should clear the end processing burr, end node and profile joint must take sealing measures, such as using waterproof glue, to prevent structural seepage.
