We repair the rural areas, the drawings said with 70 series push aluminum alloy doors and windows, but the building side said that with aluminum doors to add money, so I asked 70 series push and pull aluminum alloy door in the end what is the standard, very grateful
70 series refers to the window frame width of 70 mm,
70 series, specify the window frame is the overall width of 70MM, and glass is not directly related to the glass can be set according to customer requirements.
In general, many manufacturers of standard doors and windows models are the thickness of the doors and windows of the specific size to mark, 70 series push and pull aluminum alloy door is the door frame in the wall of the width of the part of the size of 70 cm or so, be relatively small series , Generally do the window with such a narrow width, do the door is best to use the door frame 80 cm width above is better, of course, but also to see the thickness of the cross section, generally do the best 1.2 thick material is better. If you want to save money, then choose the most simple slightly, but not practical.
