1. The meanings of 60, 80, 90, 88, push-pull and flat-open in uPVC Profile are as follows
The 60, 80, 90, 88, etc. in uPVC Profile mean the profile series. Generally speaking, the profile series is based on the width of the profile. For example, the cross-sectional width of the frame of the 60 series is 60 mm.
Push-pull and flat-open means the way doors and windows are opened. Flat-open means that the side of the window hinge (hinge) is installed to open the door and window inward or outward. Push-pull means that the vertical sash of the door and window surrounds the door and window that is pushed and pulled in the horizontal direction.
2. Aluminum alloy, Window and Door Profile sliding and flat opening have the following differences
1. Different appearance
The building adopts aluminum casement windows, which can make the facade effect of lines. For windows with large partitions from floor to ceiling, turning on the fan takes up a small part of the whole window. Aluminum alloy sliding windows can only be pushed and pulled, and are generally more suitable for clearer horizontal and vertical lines to open factories or rural households.
2. Different performance
The cross section of casement window profile is small, but its main rod material or vertical material has corresponding strengthening treatment in the design process, so its wind pressure resistance performance is better.
The upward and downward stile pulleys of the sliding window to withstand horizontal wind loads are generally not ideal, so the wind pressure resistance performance is slightly worse.
