If you want to install aluminum alloy doors and windows up to the standard, the standard of hardware is the prerequisite. What kind of aluminum door and window hardware can be considered as up to standard, and what are the standards for selecting aluminum alloy doors and windows?
1、 Material selection standard for aluminum profiles
The main structure of aluminum alloy doors and windows is composed of profiles, and the profile standard must meet the requirements of GB / t5237-2400 aluminum alloy building profiles.
2、 Selection standard of hardware
In addition to meeting the standards, the hardware should be able to match the configuration of aluminum alloy profiles. Only high-quality profiles and corresponding hardware accessories can form a complete set of aluminum alloy doors and windows.
We all know the material selection standard of profiles. As long as the experienced people can understand the inspection of hardware, but often some trivial aspects can't arouse our attention. The following is a detailed introduction of seven points for attention on the standard of aluminum alloy door and window hardware accessories:
1. Aluminum alloy door and window hinge
The bearing capacity of aluminum alloy doors and windows is the key to the safety and smooth opening and closing of aluminum alloy doors and windows. The bearing capacity of hinges is stronger than that of friction hinges, so hinges can be used to make window sashes with larger grids, and friction hinges are only applicable to windows with smaller partitions or upper suspension windows.
2. Aluminum door and window handle
Aluminum door and window handle is an important part related to the safety and sealing performance of doors and windows. The ordinary handle is only applicable to the window sash with small partition and load, while the European multi-point handle is suitable for the window sash with large partition and load.
3. Sealing strip
The sealant strip between the frame and fan is the guarantee of air tightness and water tightness of aluminum alloy casement window. The effective sealing ratio of original PVC adhesive strip is about 5 years. The Recycled PVC strips have no sealing effectiveness. It is ideal to use EPDM rubber with good weather resistance.
The pulley of aluminum alloy doors and windows is required to be smooth when opening and closing doors and windows. The manufacturer of aluminum alloy doors and windows recommends using rolling shaft nylon wheel.
5. Anti falling sealer
The aluminum alloy anti falling sealer can ensure the safety of the window sash from falling off. At the same time, it has the sealing function between the hook and the upper slide. ABS plastic and EPDM with good durability ratio should be used.
6. Lower sealing block
The lower seal plays a sealing role between the hook and the glide way, which can effectively prevent water splashing under the action of fluctuating load. EPDM should be used.
7. Wool top
The top is the seal of window sash and window frame, which determines the air tightness of aluminum alloy doors and windows. Ordinary chemical fiber wool will curl and lose sealing effect when meeting water, so silicified wool must be used.
