3 major points of aluminum alloy doors and windows to buy home decoration solutions
1. Check the materials. 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 at least 1.2 mm, with a tensile strength of 157 Newtons per square millimeter and a yield strength of 108 Newtons per square millimeter. The oxide film should be 10 microns thick. If these standards are not met, it’s likely that the product is low quality and unsafe for use.
2. Examine the craftsmanship. Premium aluminum alloy doors and windows are manufactured with precision, featuring smooth edges, accurate installation, and excellent sealing performance. They open and close easily without resistance. On the other hand, inferior products often use poorly selected aluminum profiles, leading to rough processing, improper cutting instead of milling, and incorrect installation. This results in poor sealing, potential water leakage, glass breakage, and even structural failure under strong winds or external pressure. In some cases, the moving parts can be damaged or the glass can shatter, posing a risk to people nearby.
3. Consider the price. High-quality aluminum alloy doors and windows typically cost about 30% more than their lower-quality counterparts due to higher production costs and better materials. However, some cheaper options use aluminum profiles with a wall thickness as low as 0.6–0.8 mm, which fall far below the required strength and safety standards. These products are not only less durable but also potentially dangerous, especially in harsh weather conditions.
When choosing aluminum doors and windows, it's essential to look beyond just the appearance and focus on the materials, craftsmanship, and pricing. A small investment in quality can save you from costly repairs and ensure your home remains safe and comfortable for years to come.
