How to distinguish the quality of building aluminum profiles

[China Aluminum Industry Network] 1. Always check the product's factory certification, paying close attention to the manufacturing date, specifications, technical requirements, company name, and production license number. This ensures you are purchasing a genuine and high-quality product.

2. Be sure to examine the wall thickness of aluminum alloy products, especially for doors and windows. The material thickness should not be less than 1.2mm to ensure structural integrity and durability.

3. Inspect the surface of the product carefully. It should have a bright and even color with good gloss. Avoid any products that show visible scratches, dents, bubbles, or other surface imperfections.

4. Pay attention to the thickness of the surface coating. For anodized aluminum profiles, the film thickness should be at least 10μm. Electrophoretic coatings must be no less than 17μm, while powder coatings should fall within the range of 40-120μm. For fluorocarbon-painted products, two layers are recommended, with each layer being at least 30μm thick.

5. When performing regular maintenance, avoid using hard cleaning tools such as brushes. Instead, opt for soft cotton yarn or cloth to prevent damage to the surface.

6. You can use water, mild detergent, or soap for cleaning, but avoid using harsh organic solvents or chemicals that may harm the finish.

7. If you live in a coastal area, it's advisable to choose aluminum products with excellent corrosion resistance, such as electrophoretic paint, powder-coated, or fluorocarbon-sprayed aluminum. These options are more suitable for environments with high humidity and salt content, ensuring long-term performance and aesthetics.

In addition, always store aluminum products in a dry and well-ventilated area to maintain their quality over time. Regular inspection and proper maintenance will significantly extend the lifespan of your aluminum products.
