AA25 grade anodized film advantages

【China Aluminum Industry Network】 1. Good corrosion resistance Due to the influence of industrial pollution and adverse weather and environmental impact, the corrosion of the anodic oxide film on aluminum alloy doors and windows and curtain walls has been exacerbated, shortening the service life of aluminum alloy doors and windows and curtain walls. . The AA25 grade anodized film is suitable for use in harsh environments due to its high film thickness and good corrosion resistance.

2, excellent acid resistance Due to environmental pollution, in many places there will be the phenomenon of acid rain, resulting in aluminum alloy doors and windows, curtain wall surface discoloration, loss of light and other defects, thereby shortening the use of aluminum alloy doors and windows, curtain walls life. The AA25 grade anodized film has good acid resistance, can withstand the erosion of acid rain, and ensure the service life of aluminum alloy doors and windows and curtain walls.

3, oxide film surface hardness, good wear resistance AA25 grade anodic oxide film in the aluminum surface to form a thick and dense oxide film layer, improves the aluminum surface hardness, has good wear resistance, can withstand the long years of sandstorm Etching, and scrubbing as regular maintenance of aluminum alloy doors and windows and curtain walls.

Aluminum Spiral High Speed Door

The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.

Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
