1.Floor spring selecting shall considering the weight of the door. Different weight door will require different type floor springs. 

 

2.Glass weight measurement (China national standard glass) method: 

 

 3.thickness = 1mm,  1 square meter glass weight shall be 2.5 kg, as usual thickness shall be 12mm, height of door= 2.3m, width= 1m, total weight of the door glass shall be 2.3*1*12*2.5=69KG.

 

4. With weight of all hardware components shall earn the total weight of the door. 

 

5.A heavy duty spring for a light door will be a wast to the door cost, which also can not earn a satisfy working performance. 

 

6.Carrying too much weight for a spring will reduce the working life.

 

7. Cause of the wind, a twin spring will need when doors were used in an open air environment. A twin spring will work better when locating at 0º and 90º position.
