Door and window hardware accessories damage generally manifests as: hardware accessories are not firmly fixed, loose and fall off, pulleys, sliding support hinges and other damage and inflexible opening and closing. Let ’s take a look with the editor of Mtuosi Door and Window Hardware System: The reasons for the damage to hardware accessories:
Incorrect selection of hardware accessories, poor quality; no metal lining board is provided when tightening, and there is insufficient installation strength.
Measures to prevent damage to hardware accessories:
1. The type, specification and performance of the selected hardware accessories shall comply with the current national standards and relevant regulations, and match the selected doors and windows.
2. For sliding windows with a width exceeding 1m, or double-glazed doors and windows, double pulleys or rolling pulleys should be used.
3. The sliding support hinge shall not be made of aluminum alloy material, but shall be made of stainless steel.
4. Use metal screws to install hardware accessories with fastening screws. The thickness of the metal lining should be at least twice the tooth pitch of the fasteners. Do not fasten to plastic profiles or use non-metallic linings.
5. Hardware accessories should be installed last, door and window locks, handles, etc. should be assembled after the windows and doors are fanned into the frame to ensure the correct position and flexible switching.
6. Pay attention to maintenance after installation of hardware accessories to prevent rust and corrosion. In daily use, lightly open and close lightly to prevent hard opening and hard closing, causing damage.
