A: Both anodized and painted aluminum should be cleaned regularly. For small towns and areas in the interior of the country that are not affected by aggressive elements such as air pollution or salty air, cleaning aluminum when cleaning glass is sufficient. Aluminum should be cleaned with warm water and a diluted non-ammonia-free, non-aggressive, non-acetic acid detergent. You should then rinse the aluminum thoroughly with clean water and dry it with an absorbent cloth. In urban areas or areas near the sea, aluminum should be cleaned more frequently and more thoroughly. Areas that are not exposed to rain should be cleaned more frequently than other surfaces. If water and mild detergents are not enough to clean aluminum windows, you can use cleaners specially developed for aluminum surfaces. These cleaners contain mildly abrasive ingredients and can be used with synthetic cleaning cloths. In all cases it is important to rinse the surface thoroughly with clean water and dry thoroughly, especially the corners and bottom contours. To protect and extend the life cycle of aluminum, an available waterproofing membrane coating can be treated with a very thin clear layer.

A:Aluminum can be extruded into complex shapes to precise tolerances. Aluminum can be made into thousands of unique profiles, each of which meets many specific structural and aesthetic requirements. It is this ability to provide simple and elegant solutions to extremely complex design problems that leads to aluminum's enduring appeal. Aluminum was chosen for outdoor use because it is a stable, corrosion-resistant and lightweight metal. One of the main attractions of aluminum to specifiers is its exceptional strength-to-weight ratio. At 2.7g/cm2, aluminum is 66% lighter than steel. It is also less prone to brittle fracture. In fact, when comparing aluminum and steel structures, aluminum's greater modulus of elasticity means that a 1:2 weight ratio is easily achieved. It can also be machined at high cutting speeds and does not require welded connections. These advantages help reduce manufacturing time.

A:The heat transfer coefficient (k or U value) is the amount of heat transferred per unit time (per degree Kelvin of the difference between the internal and external temperature) through a 1 square meter glass surface. A measure of the rate of non-solar heat loss or gain through a material or component. The lower the U-value of a window, the less non-solar heat it transmits.

A: The aspect ratio of any item is the proportional relationship between its width and height. It is usually expressed as two numbers separated by a colon, such as 16:9. In the case of windows, it all depends on the window dimensions given by the architect/designer/specifier. Manufacturers can always refer to the maximum and minimum size restrictions given by AIS in the guidelines. It plays an important role in the structural stability and function of the window. For example, in sash systems, the recommended aspect ratio is 1:1.5. And in sliding, the aspect ratio should be less than 1:2.5
