The common height range for traffic sign poles typically varies from 3 to 6 meters, with some taller poles used in specific scenarios. These poles are installed using different methods, such as direct burial, flange mounting, or base plate installation. They are commonly used in a wide range of application scenarios, including urban streets, highways, parking lots, and construction sites, to support and display traffic signs, ensuring clear and visible guidance for road users and enhancing road safety.
