Structural Comparison: Conventional Swing Doors vs. Balanced Doors 

The conventional swing door system currently holds a large market share and demand, with its main advantages being the full 180° free opening of the door leaf and high cost-effectiveness.

However, as the demand for ultra-high and oversized door bodies in modern buildings increases year by year, traditional swing door systems (door closers and floor springs) can no longer fully meet the design, usage, and safety requirements of many projects. Therefore, balanced door series products, as a subcategory of swing doors, have emerged. Their unique product advantages, which distinguish them from ordinary swing doors, have also gained increasing recognition and praise from customers.
