How to make reasonable use of hardware accessories for aluminum doors and windows?

A good set of door and window hardware is enough to enhance the value of a door and window system. Although door and window hardware accessories are just a series of small accessories, they play an inestimable role in the overall construction of door and window systems. So, how to make reasonable use of hardware accessories for aluminum doors and windows?

 Hardware accessories are the key components that determine the performance of doors and windows. They are responsible for tightly connecting the frames and sashes of doors and windows. Without them, doors and windows will only become dead sashes and lose the meaning of doors and windows. The design of aluminum doors and windows is the architectural design that considers the performance of doors and windows first, to meet the functional requirements of the building as the goal, and reasonably determine the performance and related design requirements of aluminum doors and windows. Today, the editor will analyze the role of hardware accessories on doors and windows from the performance and functions of doors and windows:

 1. The physical performance indicators of doors and windows include: wind pressure resistance, air tightness, water tightness, heat preservation, heat insulation, sound insulation and wind pressure resistance.

When the inner casement window is under positive wind pressure: the hardware lock points are stressed, so multiple lock points should be used. The more locking points, the smaller the force applied by each locking point to the middle leg, and the smaller the relative deflection of the deformation.

When the inner casement window is under negative pressure: the frame is stressed.

When the outer casement window is under pressure: the locking point is stressed, so it is advisable to adopt multiple locking points. The more locking points, the smaller the force applied by each locking point to the middle leg, and the smaller the relative deflection of the deformation.

When the outer casement window is subjected to positive wind pressure: the frame is stressed.
