Floor Spring Introduction





Floor Spring Installation




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.
