Causes of hardware damage:
Improper selection of hardware accessories, poor quality; metal liners are not provided when tightening, and there is not enough installation strength.
The damage of plastic door and window hardware accessories generally manifests as: the hardware accessories are not fixed firmly, loose and fall off, and the pulleys, sliding hinges, etc. are damaged, and the opening and closing are not flexible.
Measures to prevent damage to hardware:
The type, specification and performance of the selected hardware accessories shall comply with the current national standards and relevant regulations and be matched with the selected plastic doors and windows.
To install hardware using fastening screws, metal liners must be installed. The thickness of the liner should be at least twice that of the fasteners. Do not fasten on plastic profiles or use non-metallic linings.
Hardware fittings should be installed lastly. Door and window locks, handles, etc. should be assembled after the window leaf is in the frame to ensure correct position and flexible switching.
After installing the hardware, pay attention to maintenance to prevent rust corrosion. In daily use, you must lightly open and close the door to prevent it from being hard-opened and hard-closed, resulting in damage.
For a sliding window with a width of more than 1m, or doors and windows with double glazing, double pulleys or rolling pulleys should be used.
Sliding hinges must not be made of aluminum alloys. Stainless steel should be used.
