3.  With double closing speed adjusting valves at 105°~0°to match different closing purposes;

4.  General designed is suitable for openning doors with left/right hand and single/double opening,accessories are available for each  usagemode.

 

Suggestion:

1. The choice of floor spring is on the basic of the load-bearing of floor spring.

2. The way of calculate the door weight:    According to standards, the weight of 1mm thickness glass is 2.5KG per square metre.     For example, the glass is 12mm thickness, 2.3M high, 1M wide, so its weight is

               2.3*1*12*2.5=69KG/one square metre.3. The load-bearing of floor spring is the weight of door and the accessories.

4. If the door is light, choose the heavy-duty floor spirng, that will increase the cost    and door can't run well.

5. If in order to reduce the cost, choose the light-duty floor spirng, it will reduce the    the working life of floor sping.

6. If the door is in outside, no matter the door is weight or light, it must choose the    double cylinder floor spring. It's to consider the wind power. Double cylinder floor    spring can be good positioning in 0 degree and 90 degree then single cylinder.

7. It must choose the floor spring that mix the antifreezing oil in cold area.
