What is the thickness of bridge-cutoff aluminum alloy? This first depends on which series it is.
50 series , the total width is 5cm , wall thickness is National Standard 1 .4mm.
55 series , the total width is 5 .5cm , wall thickness is National Standard 1 .4mm.
60 series , the total width is 6cm , wall thickness is National Standard 1 .4mm.
65 series , the total width is 6 .5cm , wall thickness is National Standard 1 .4mm.
70 series , the total width is 7cm , wall thickness is 1 .8MM.
80 series , the total width is 8cm , wall thickness is 2 .2MM.
So what do these so-called 55, 65, 70, 80 mean , what does it represent?
Simply put , these numbers represent the width occupied by the broken bridge aluminum window frame falling on the windowsill. For example, 55 series means that the width occupied by the window frame falling on the window sill is 5 .5cm , from this we know ,60 is 6cm ,65 is 6 .5cm ,70 is 7cm ,80 is 8cm.
