Uses of hardware accessories for doors and windows

🔒 Multi-locking point form
When the inner casement window is subjected to positive wind pressure, the hardware lock points are stressed, so it is advisable to adopt a multi-locking point form. The more lock points there are, the smaller the force exerted on the center support by each lock point, and the relative deflection of the deformation is also smaller.
👀 Limited wind pressure resistance
The window sash fixing points of the sliding window are the upper and lower guide rails, so its wind pressure resistance is also limited.
🏢 Strict requirements
Modern buildings have increasingly higher requirements for energy saving and other functions, and have strict requirements for the sealing and insulation, air tightness and water tightness, sound insulation and wind resistance of windows, and even the anti-theft level.
