Multi-Dimensional Triple Cantilever Road Sign Pole

·Structural Strength: The pole body is made of high-quality Q235B/Q355B low-carbon steel. The wall thickness has undergone rigorous finite element stress analysis calculations to ensure extremely high torsional and overturning resistance while bearing the loads of signs in three directions.

·Corrosion Protection: The poles, crossarms, flanges, and all fasteners undergo strict hot-dip galvanizing treatment. The uniform and dense zinc layer effectively prevents oxidation of the steel by air, providing corrosion protection for over 20 years.

·Connection Technology: The three cantilever arms are connected to the pole via multi-directional flanges or reinforced clamps, ensuring full weld seams at the connections and ultrasonic flaw detection to meet high-strength wind resistance requirements.

·Appearance Customization: Outdoor-specific electrostatic powder coating is supported on a galvanized base, with colors customized according to urban visual standards, providing both aesthetics and an additional layer of chemical protection.

Primarily used in extra-large intersections, complex five-way junctions, merging and diverging points of urban overpasses, and highway interchanges. It is often used to simultaneously mount speed limit signs, directional signs, and lane guidance signs, achieving comprehensive traffic guidance at a single visual intersection.

·Problem: Vibration coupling between cantilever arms causes irregular vibration of the pole.

Solution: Optimize the length ratio and wall thickness distribution of the cantilever arms during the design phase to avoid resonant frequencies; install damping shock absorbers at the ends of the crossarms.

·Problem: Inconsistent wind exposure across multiple panels leads to unbalanced force on the pole.

Solution: Before construction, the reinforcement quantity and depth of the concrete foundation must be re-checked based on the actual total area of ​​the signboard, and the load-bearing capacity of the anchor bolts must be increased.

·Important Notes: Due to the extreme weight and wind force of the three-cantilever structure, the quality of the concrete foundation pouring is crucial for safety. The embedment depth must be strictly calculated based on the bearing capacity of the foundation. A large-tonnage crane must be used during installation to ensure balanced lifting of the three cantilever arms. It is strictly forbidden to increase or enlarge the signboard area without load-bearing calculations.
