Hardware of high-grade windows is made of metal, and its internal strength, appearance and usability directly affect the performance of windows. Many middle and low-grade plastic steel windows are made of plastic hardware, and there are great hidden dangers in their quality and life.
The quality of hardware fittings affects the price of windows to a great extent. For example, the quality difference between imported hardware and domestic hardware is very large. Imported hardware is usually used 20,000 times without fault. At present, the hardware of high-grade doors and windows such as Mercedes-Benz is imported from Germany. Some manufacturers use imported products in key parts and domestic products in general parts.
