Product Description


      When closed, high-strength nylon wheel center around the spring galvanized pipe  rotation, the already tightening the spring due to the generation of torque (or  rotational force) naturally relax, help to close. However, when closing the  other side of the corresponding spring are taut. When open, the spring tension  of the torque due to the effect of natural door body back to their original  position to achieve the purpose of the booster.

Normally,  the market of such springs are usually dense body, but between the coils in the  twisting process will naturally distorted, generating too much resistance,  affecting the normal operation of the rolling gates. Therefore, Fiat door  industry under long-term testing, coils pitch adjustment width of 2mm to reduce  friction, avoid them generate resistance to rotation or rotational  force.
