Aluminum profile maintenance and maintenance

【China Aluminum Network】 aluminum products, has the characteristics of high strength, light weight, strong corrosion resistance, novel construction, easy installation, saving materials, durable, it is unreasonable maintenance, installation and protection will also affect the aluminum The shape of the profile goods is beautiful and the appearance of color. Therefore, there should be accurate measures for conservation and protection.

1. During the transferring process of aluminum profiles, they must be handled with care and care. Be careful not to bump the surface and form a bump on the outside, which will affect the appearance.

2. During the transportation of aluminum profiles, it must be covered with a rag. Beware of the intrusion of rain and snow.

3, aluminum storage environment should be dry, bright, outstanding ventilation, non-corrosive climate, together should guard against rain, water, snow intrusion;

4. When the aluminum profiles are stored, the bottom of the aluminum profiles must be separated from the ground with a pad, and the interval between the adherence to the ground is greater than 10 cm;

5. When aluminum profiles are stored, they must not be stored together with chemical data and moisture data.

6, aluminum profiles in the installation process, the appearance must be affixed waterproof tape, and the wall of the box touch, must ensure that the profile of the oxide film and paint film is not damaged, with the use of qualified cement, sand;

7. After processing into the door and window, clean the aluminum surface with a net cloth and a neutral detergent regularly.
