Typhoons have always been a severe challenge to production and daily life in various regions. The occurrence of typhoon weather is often accompanied by strong wind pressure. The wind pressure test in coastal areas is much greater than that in inland areas, and the maximum wind pressure value can differ by more than twice. If this location is closed or doors and windows are customized, safety calculations are particularly important.Hurricane proof door is suitable for places where require wind, pressure, typhoon and even hurricane resistance.should be able to block shock waves and meet corresponding resistance requirements. When selecting, not only should the size of the opening be met, but also the design pressure requirements should be met.

Gale weather is the key to testing the wind pressure resistance performance of doors and windows. Wind is the driving force behind phenomena such as deformation, damage, cold air infiltration, rainwater leakage, and wind and sand entering buildings in doors and windows. Due to different factors such as the geographical location and height of buildings, as well as the different installation positions of doors and windows, they may be subjected to alternating positive and negative wind pressures. When subjected to excessive wind pressure, it may cause deformation of doors and windows, glass breakage, damage to hardware parts, and drop of window sashes, resulting in safety accidents.

Wind pressure resistance performance of Hurricane proof Door

Simply put, it refers to the ability of doors and windows to withstand wind. Wind pressure refers to the pressure on the surface under wind load conditions, which is divided into positive and negative wind pressures.

Positive wind pressure refers to the forward wind pressure generated by the wind blowing directly on building doors and windows, which is consistent with the direction of the wind. Positive wind pressure causes bending of the frame structure profile box inside the doors and windows.

Negative wind pressure refers to the suction force generated by non direct wind blowing through building doors and windows, which causes the frame structural profiles in the doors and windows to bend outward.

So the wind pressure resistance of doors and windows refers to the ability of door and window frame profiles to maintain stability under positive and negative wind pressure conditions.

The strength of the profile mainly focuses on the structural strength verification of the door mullions, because the main load-bearing plate of the door when subjected to wind pressure is glass, and the deflection deformation force of the glass is directly transferred to the mullions. Therefore, we enhance the structure of the door mullions, choose door and window hardware with extremely strong wind pressure resistance performance, and at the same time, the thicker the requirement for the thickness of the glass original sheet, the safety measure for disguised thickening is to use adhesive. Tempered glass has a significant contribution to the improvement of glass strength, and a more important role is to reduce the particle size during glass breakage to reduce harm to the human body. We have also conducted strict testing on our Hurricane proof door in relevant institutions.
