[China Aluminum] As the times progress, more and more people are paying attention to their quality of life, and the comfort and aesthetics of their living environment have become key concerns. In recent years, aluminum alloy doors and windows have gained popularity among consumers, becoming a common sight in homes across China. Today, we're sharing six important factors to consider when choosing aluminum alloy doors and windows.
1. Thickness: There are different series available for aluminum sliding doors, such as the 70 series and 90 series. For indoor sliding doors, the 70 series is typically sufficient. The series number refers to the thickness of the frame in millimeters. For sliding windows, you'll find options like the 55 series, 60 series, 70 series, and 90 series. The choice should be based on the size of the window opening and the local wind pressure. If you're using sliding windows for a closed balcony, it's recommended to go for at least the 70 series.
2. Strength: The tensile strength should be at least 157 N/mm², and the yield strength should reach 108 N/mm². When purchasing, you can gently bend the profile with your hand and check if it returns to its original shape after releasing. This helps assess the material's durability.
3. Color: The color of the aluminum profiles should be consistent throughout. If there’s a noticeable color difference, it may indicate poor quality and should be avoided.
4. Flatness: Inspect the surface of the aluminum profiles for any dents or bulges. A flat surface is essential for both appearance and performance.
5. Gloss: Avoid purchasing doors and windows with surface imperfections such as bubbles (white spots), ash (black spots), cracks, burrs, peeling, or other visible defects. These can affect both the aesthetics and longevity of the product.
6. Oxidation Level: The oxide film on the surface should be at least 10 microns thick. To check this, you can lightly touch the surface with your finger. If the oxide layer comes off easily, it may not meet the required standards.
Choosing the right aluminum alloy doors and windows involves more than just looking at the design. It's important to evaluate these key factors to ensure you get a durable, high-quality product that enhances your home's comfort and style.
