      1、传动链条的问题:这个对于以后是至关重要的,一般情况下,配备的链条都是比较小的,耐磨性比较差,在长时间的使用中会出现断裂的可能。济南卷帘门
      1, drive chain problem: this is the most crucial for later, in general, equipped with chain is relatively small, with poor wear resistance, in the long time use will appear the possibility of fracture.
      所以在使用的时候一定要查看,若是不满足自己使用的,要求厂家给换一条结实的。
      So at the time of use must check, if can not meet the needs of their own use, a strong request factory to change.
      2、卷帘门预卷的问题,标准的济南卷帘门,在全部拉下来的时候,上面还会留下一圈,这个是为了防止因为门帘的重量使得它在拉力的作用下,出现破裂。
      2, problems in the process of the volume, standard of jinan shutter, in all down, would leave a circle on the top, this is to prevent because the weight of the door made it under the action of tension and rupture.
      但是很多的厂家未必都做到了这一点,查看的时候也没有办法验收,所以使用时间长了,会出现掉下来的危险。
      But many manufacturers may not have done this in the past, see also have no way of acceptance, so long time, will be in danger of falling.
      3、门帘地量问题:在我们看到的门之中,有的带有底梁,有的没有,若是有的话,也是不怎么好的料。
      3, door curtain quantity problem: in the gate, we see some with sill, some not, if any, is also not very good.
      其实这个在整个门之中还是重要的,起到固定的作用,要是没有边框,在遇到大火的时候,容易掀翻门帘。
      Actually the among the whole door is one of the most important, have the effect of fixed, without borders, in case of fire, easily overturned the curtain.
