Highway Gantry Traffic Signal Pole

Product features:

The Highway Gantry Traffic Signal Pole offers excellent load-bearing capacity and reliability for high-speed road scenarios. Its box-shaped steel beam structure provides superior bending and torsional resistance, supporting heavy equipment such as large LED VMS displays and multiple traffic signal heads without deformation. The hot-dip galvanization + epoxy coating double anti-corrosion treatment ensures long-term performance in harsh environments, including coastal highways with salt spray and mountainous expressways with temperature fluctuations. The gantry design allows signal placement directly above traffic lanes, ensuring maximum visibility for drivers even in heavy rain or fog. Additionally, the modular beam design simplifies transportation and on-site assembly, reducing construction time for large-scale highway projects. This product addresses critical pain points such as insufficient signal visibility for wide highways, interference with large vehicles, and high maintenance costs for heavy-duty infrastructure.

Product specifications:

The Highway Gantry Traffic Signal Pole features robust technical parameters to meet highway engineering standards. The span ranges from 15 to 30 meters, with a height of 5 to 7 meters above the road surface to accommodate large vehicles. The core structure uses Q355B high-strength steel beams with a cross-section of 400mm x 200mm x 10mm, providing a load capacity of up to 2000kg for signals and VMS displays. It can withstand wind speeds of up to 50m/s (Level 15), ensuring stability during extreme weather events such as typhoons. The surface treatment includes hot-dip galvanization (minimum thickness 85μm) followed by epoxy coating (minimum thickness 60μm), meeting ISO 1461 and ISO 12944 standards for corrosion resistance. The installation requires two concrete foundations (1200mm x 1200mm x 2.5 meters each) on both sides of the road, with steel anchor bolts for secure fixation. The beam is prefabricated with mounting brackets for traffic signals and VMS displays, reducing on-site drilling and welding work. All components undergo non-destructive testing to ensure structural integrity.

Product application:

This pole is exclusively designed for high-speed and high-flow road networks. Highways and intercity expressways are its primary application areas, as the gantry structure provides uniform signal coverage for multiple lanes, ensuring consistent traffic guidance for high-speed vehicles. Urban expressways and ring roads use it to install variable message signs, providing real-time traffic updates such as congestion alerts and accident notifications to drivers. Tunnel entrances and exits also benefit from this pole, as it can display warning signs and traffic signals to guide vehicles through transition zones. Additionally, it is suitable for toll station plazas and border checkpoints, where it can integrate traffic signals with access control systems. Highway management bureaus, transportation infrastructure companies, and toll road operators are the core target customers, as the pole’s durability and load capacity align with the long operational life of highway infrastructure.
