measures to prevent hardware damage:

1. The model, specification and performance of the selected hardware accessories should comply with the current national standards and relevant regulations, and match the selection of plastic steel doors and windows

2. For sliding windows with a width of more than 1 meter, or doors and windows with double glazing, double pulleys should be set, or rolling pulleys should be selected

3. The sliding brace hinge shall be made of stainless steel instead of aluminum alloy

4. When installing hardware with fastening screws, a metal lining plate must be set inside, and the thickness of the lining plate should be at least twice the tooth pitch of the fastener. It shall not be fastened on plastic profiles, nor shall non-metallic linings be used

5. Hardware fittings should be installed finally. Door and window locks, handles, etc. should be assembled after the window is placed in the frame to ensure correct position and flexible switch

6. Pay attention to maintenance after hardware installation to prevent rust and corrosion. In daily use, it is necessary to close and open gently to prevent damage caused by hard closing and hard opening. At present, die-casting hinges are widely used in the market. This kind of hinge is made of zinc alloy by direct die casting, so the quality of zinc alloy is very important. The brand of zinc alloy is different, and the quality will be different. Generally speaking, because the hinge is a very important hardware, the zinc alloy selected is also better than the zinc alloy of other hardware. If zinc alloy with impurities is selected, the hinges produced will be brittle, and the bearing capacity is not strong. It is easy to fracture after loading. In addition, the die-casting process of zinc alloy also seriously affects the quality of hinges. In view of the fact that the raw materials of hinges are generally difficult to identify, it is recommended that consumers buy products of regular manufacturers to ensure quality
