There are 728, 768, 868 these three kinds of Aluminum. It is just the codes for the specification of Aluminum without any professional definition. However there are many differences from the specifications in the material thickness, the width between the orbital frame, design, and application. In thickness, diamond window of the future is 1.2mm thick, of which 728, 768 are 1mm thick. Of course,the aluminium supplier should pay more attention to the same material, thickness of greater intensity is higher, but not home decoration must use 1.2 thick aluminum, according to some companies renovation experience, 1mm thick aluminum is also capable of high building balcony needs.
The Specifications of Aluminum
The specifications of the section width also are not identical, and it not means that the larger the number, the wider. In profile design, 868, 768 are used by circular rail, 728 are used by the monorail. Generally speaking, a circular rail sliding smoother with high strength, water tightness, and its air tightness is also a little better, but this not means that the monorail is not smooth, because in the design, the monorail is generally done single-layer glass, and double track is generally double or vacuum glass, one can imagine, double glass weight than single-layer glass a much heavier. To sum up, if the window insulation, thermal insulation and has no special requirements can select 728; if you also want insulation you can select 768868.
Consumers in Purchase of Aluminum Profiles
Consumers in the purchase and use of aluminum alloy extruded profiles for architecture products should pay attention to the following points: First, to check the aluminum products factory certificate, and pay attention to the date, specifications, technical conditions, business name and production license number. Second, to scrutinize the aluminum surface of the product, and the product should be in bright color, good luster, and its surface cannot have obvious scratch, bubble etc. Third, you must pay attention to the aluminum products wall thickness, doors, window materials products thickness shall be not less than 1.2mm. Forth, pay attention to aluminum products surface coating thickness, anodic oxidation product film thickness of not less than 10 μ m, electrophoresis painting product film thickness of not less than 17 μ m, powder spraying coating thickness not exceeding 40-120 μ m, fluorocarbon paint products should be in two with more, not less than 30 μ M. You can choose aluminium sheet as trying. Fifth, coastal regions user needs choosing the best corrosion resistance of electrophoresis coating aluminum profiles, powder spraying aluminum or fluorocarbon spraying profiles products.
Maintenance time of Aluminum
First, in routine maintenance, you cannot use the brush and other hard objects as a cleaning tool but you should choose soft cotton yarn and cotton fabric. Second, when cleaning water, you can use detergent or soap but not other organic matter.
