Three-roll gate introduction

Three-roller gates are also called three-pole gates, three-roller gates, three-roll gates, roller gates, and roll gates. The barrier (gate bar) consists of 3 metal bars forming a spatial triangle, generally using a hollow closed stainless steel tube, which is strong and not easy to deform, and achieves blocking and passage through rotation. From the core control method, it is divided into mechanical type, semi-automatic type, and fully automatic type. From the form, it is divided into vertical and bridge type. The vertical three-roller gate has a smaller volume and is easier to install; the bridge-type three-roller gate has a longer channel and higher security. Advantages of three-roller gates: They can very effectively achieve single-person passage at a time, that is, only one person can pass at a time, and the safety and reliability are relatively high. The cost is relatively low. It has strong waterproof and dustproof capabilities, strong adaptability to the environment, and is suitable for both outdoor and indoor use. Suitable for ordinary pedestrians and occasions where the traffic flow is not large or pedestrians do not take good care of it when using it, as well as some harsh outdoor environments.
