A balanced door is a kind of swing door mostly used as an exterior entrance door in a public or commercial building. It is different from all kinds of hinge doors as its unique hardware and mechanical design allow itself to bear and efficiently operate a tall and heavy door leaf. The pedestrians can open it easily without much pulling or pushing force, and the door leaf can make a full close by itself.
The reason making it a “balanced” door is that the exterior wind pressure is distributed by its unique swing path, the location of the door swing fulcrum point makes the door open with ease by leverage and the pivot spring force overcomes the interior stack pressure to fully close the door.
