Hardware fittings are the parts that are responsible for the close connection between the frame of the door and the window and the fan. Without its existence, the doors and windows will only become dead fans and will lose the significance of the doors and windows. From the performance and function of doors and windows, we analyze the role of hardware accessories on doors and windows physical performance indicators are: wind pressure resistance, airtightness, watertightness, insulation, heat insulation, sound insulation, wind pressure resistance.
When the inner flat open window is under positive wind pressure; the hardware lock point is forced, so it is better to use multiple lock points. The more lock points, the smaller the force that each lock point exerts on the midline, and the less deflection of the deformation. When the inner casement window is under negative pressure: the frame is stressed. When the external casement window is under pressure: the lock point is subjected to force, so it is better to use multiple lock points. The more lock points, the smaller the force that each lock point exerts on the midline, and the less deflection of the deformation.
