Teach you how to choose aluminum alloy doors and windows

The tensile strength and yield strength are significantly lower than the relevant national standards and regulations. The aluminum profiles used for high-quality aluminum alloy doors and windows are made of high-purity A00 aluminum without doping waste aluminum. The material is pure, and the thickness, strength, and oxide film of the profiles comply with the relevant national standards and regulations. The wall thickness is above 1.2 millimeters, the tensile strength reaches 157 Newton per square millimeter, and the yield strength reaches 108 Newton per square millimeter, The thickness of the oxide film reaches 10 microns. If the above standards are not met, it is considered inferior aluminum alloy profiles and it is not recommended to use them. Secondly, the selection of accessories is equally important as it directly affects the quality of finished doors and windows. High quality accessories can be combined with profiles to greatly improve the performance of the entire window.
Look at the processing. High quality aluminum alloy doors and windows, with precise profile structure design, elegant style, precise processing, exquisite installation, good sealing, waterproof, sound insulation, and insulation performance, and easy opening and closing. Poor quality aluminum alloy doors and windows, blindly selecting aluminum profile series and specifications, with simple profile structure, poor sealing and waterproof performance, difficulty in opening and closing, rough processing, using saw cutting instead of milling, incomplete use of accessories or blindly using poor quality accessories without quality assurance to reduce costs. When encountering external forces such as strong winds and rain, it is easy to experience air and rain leaks and glass explosions, In severe cases, pushing or pulling parts or glass may cause damage or injury due to strong winds or external forces.
Look at the price. In general, high-quality aluminum alloy doors and windows are priced around 30% higher than low-quality aluminum alloy doors and windows due to their high production costs and high-quality accessories. Products that are not produced and processed according to standards are not easy to meet standards. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 millimeters have tensile and yield strengths that are significantly lower than the relevant national standards and regulations, making their use very unsafe.
