Aluminum alloy doors and windows with its good decorative effect, excellent performance, and many doors and windows in the material to stand out in the modern home is widely used. Aluminum Alloy doors and windows four advantages of light weight and high strength Aluminum Alloy materials with hollow thin walled section, light weight and density is only 1/3 of the steel, the cross section has higher flexural strength, doors and windows made of very durable, not easy to deformation. Good sealing performance directly affects the use of doors and windows and energy consumption. Usually sealing refers to the tightness, water tightness, thermal insulation and sound insulation in four areas. Beautiful appearance, good decorative effect for Aluminum Alloy surface after electrochemical anodic treatment, can present a variety of colors, such as ancient copper, gold and silver lead steel etc.. The surface of the door and window with artificial oxide film, and the formation of a composite color film, gloss is particularly high, beautiful appearance. Sash frame can be bigger, mosaic larger area of the glass, so that the interior of the light, so that there is a sense of hierarchy.

Pick up the performance of the selection of materials to see the performance of this part of the main look at the heat transfer coefficient, sound insulation performance and water tightness, and the information in the purchase, you can ask businesses to provide relevant testing reports.
