3 major points of aluminum alloy doors and windows to buy home decoration solutions
1. Examine the materials carefully. High-quality aluminum alloy doors and windows are made from aluminum profiles that meet national standards in terms of thickness, strength, and oxide film. The wall thickness should be above 1.2 mm, with a tensile strength of at least 157 Newtons per square millimeter and a yield strength of 108 Newtons per square millimeter. The oxide film should be at least 10 microns thick. If these standards are not met, it’s likely that the product is low quality and may not be safe for long-term use.
2. Check the craftsmanship. Premium aluminum alloy doors and windows are produced with precision, featuring smooth edges, accurate installation, and excellent sealing performance. They operate smoothly and are easy to open and close. On the other hand, inferior products often use substandard profiles and improper dimensions. Their manufacturing process is rough, with cutting instead of proper milling, and they may not be installed according to specifications. This leads to poor sealing, which can result in air leaks, water infiltration, and even broken glass. In strong winds or under external force, the sliding parts or glass can easily be damaged, posing a risk to people.
3. Consider the price. High-quality aluminum alloy doors and windows typically cost about 30% more than lower-quality options due to higher production costs and better materials. However, some cheaper products use aluminum profiles with wall thicknesses as low as 0.6–0.8 mm, which do not meet the required strength standards. These products are not only less durable but also potentially unsafe, making them unsuitable for long-term use.
When choosing aluminum alloy doors and windows, it's important to look beyond just the appearance and consider the materials, craftsmanship, and pricing. Investing in high-quality products ensures safety, durability, and better performance over time.
