Seamless 304 Stainless Steel Pipe Bollards  , Semi Automatic Bollards IP68

Semi-automatic lifting bollards are driven by built-in gas springs for ascending and assisted manually for descending. They are widely used at vehicle access points with low traffic frequency, such as fire lanes, parks and pedestrian streets. A semi-automatic lifting bollard consists of a bollard body, a flange plate, a lifting guide system, a gas spring, a hexagon socket lock structure and other components. When used together with fully automatic lifting bollards of the same appearance, they feature cost efficiency, stability, safety, reliability and practicality, helping to reduce overall costs.
