How to choose the thickness of door and window profiles? Is thicker really better?

The thickness of door and window profiles directly affects the overall strength, but it is not necessarily the thicker the better. The reasonable thickness of profiles should be determined based on the size, opening method, and usage position of doors and windows.
For large-sized doors and windows or high-rise residential buildings, it is recommended to choose profiles with more stable structures. Professional door and window manufacturers will provide reasonable suggestions based on actual needs.
Blindly pursuing thickness may actually increase costs without achieving ideal results
