How much is the 60 series aluminum frame bridge standard size, how much is the size of the fan
In the Canton aluminum 60 series, the broken bridge is 59.2*67; the fan is 67.2*93
[60] galuminium Qianjin aluminum series insulating aluminum window size 60x53.5, window size 67.8x68.6.
60 series of insulating aluminum window size 60x53.5, window size 67.8x68.6.Distinguish the bridge aluminum, such as 55 series, refers to the broken bridge aluminum window frame width is 5.5 cm, and the aluminum 70 series refers to the broken bridge aluminum window frame width of 7 cm, the main difference between them lies above the insulation wall thickness and the width of aluminum. The aluminum 55 series and 60 series of wall thickness is the national standard 1.4MM, aluminum doors and windows insulation insulation than 60 series 55 series terms 0.5 cm, aluminum wall thickness, the difference is not, but the 55 series and 70 series of different, one is the 70 series of more than 55 of the width to 1.5 cm wide, the second is the aluminum 70 series aluminum wall thickness is 1.8MM, far better than the national standard.Hollow glass aluminum doors and windows 55 models for 5+12A+5 glass, the middle interval is 12, while the hollow glass interval of 70 series aluminum doors and windows 22, so the aluminum 70 series 55 series of aluminum than sound better. The use of aluminum in the family model 55 is enough, this is the standard engineering materials, which is the most common type of use, if the noise requirements higher, it can be considered by the German red card 70 series of ten sealing design, especially along the street district is relatively high requirements on the sound. Is the best choice.
