Hardware doors and windows play a crucial role in the functionality and security of any space. However, over time, these components can suffer damage due to various reasons. Understanding the causes and taking preventive measures is essential for maintaining their performance and longevity. Common Causes of Hardware Damage: One of the main causes of hardware failure is using low-quality or improperly selected accessories. Poor quality materials can lead to structural weakness and early wear. Additionally, if no metal lining is used during installation, the screws may not hold properly, leading to looseness and eventual damage. Inadequate installation techniques can also contribute to problems, such as improper alignment or insufficient support. Damage to plastic door and window hardware often includes loose parts, broken pulleys, or malfunctioning sliding hinges. These issues can make the door or window difficult to open or close smoothly. If the hardware isn't fixed correctly, it can cause unnecessary stress on the frame and further accelerate wear and tear. Effective Measures to Prevent Hardware Damage: To avoid these problems, it's important to choose hardware that meets current national standards and is compatible with your specific type of plastic doors and windows. Always ensure that the hardware’s size, function, and material are suitable for the application. When installing hardware with screws, always use a metal lining. The thickness of the lining should be at least twice the length of the screw. Avoid fastening directly into plastic profiles or using non-metallic linings, as they can easily break under pressure. Install hardware after the door or window has been properly positioned in the frame. This ensures accurate alignment and smooth operation. For example, locks and handles should be installed once the sash is in place to prevent misalignment. Regular maintenance is also key. Keep hardware clean and lubricated to prevent rust and corrosion. When opening or closing doors and windows, do so gently to avoid excessive force that could damage the mechanisms. For large sliding windows (over 1 meter wide) or double-glazed doors and windows, it's recommended to use dual pulleys or roller systems to distribute weight evenly and reduce strain. Sliding hinges should be made of stainless steel rather than aluminum alloy, as they offer better durability and resistance to wear. By following these guidelines, you can significantly extend the life of your hardware and maintain the efficiency and safety of your doors and windows over time.
