Are You Familiar With Octagonal Traffic Signal Poles?

The importance of traffic signal poles is well-known, hence the need for strict technical requirements to standardize their production. So, what are the technical requirements for traffic signal posts? Let's take a closer look with the introduction from the professional octagonal pole manufacturer Phoebus.

Is a thicker traffic signal pole always better?

The diameter of a traffic signal post mainly depends on the height of the upright and the length of the crossarm. The taller the upright and the longer the crossarm, the thicker and thicker the main pole's diameter and wall thickness must be. Generally, the height of monitoring poles in safe city projects is 5.5-7 meters, and the crossarm is about 6-7.5 meters. Therefore, according to national standards, octagonal traffic signal poles are made in an octagonal pyramid shape, which greatly enhances the pole's wind resistance and torsional strength.

General Technical Requirements for octagonal traffic signal poles

Octagonal traffic signal poles and sign poles should consist of an upright, connecting flange, shaped crossarm, mounting flange, and embedded steel structure.

The uprights or horizontal supports are made of straight-seam steel pipes or seamless steel pipes; the connection ends between the uprights and horizontal supports use the same steel pipes as the horizontal supports, reinforced with welded reinforcing plates; the uprights are connected to the foundation using flanges and pre-embedded bolts, reinforced with welded reinforcing plates; the connection method between the horizontal supports and the upright ends is flange connection, reinforced with welded reinforcing plates. All welds on the uprights and their main components should meet standard requirements, with smooth and even surfaces, flat, smooth, firm, and reliable welds, free from defects such as porosity, slag, incomplete welds, and missed welds.

The uprights and their main components have lightning protection functionality.

The uprights and their main components should be equipped with reliable grounding devices, with a grounding resistance ≤10 ohms.

Wind resistance: 45 kg/mh.

Surface treatment: Pickling, phosphating, hot-dip galvanizing, and powder coating.

Traffic signal pole shape: Usually a variable-diameter octagonal pole.

What are the acceptance methods and standards for octagonal traffic signal poles?

1. Wall thickness is a major technical requirement for inspection and quality control. 1. Due to the presence of caps and flanges at both ends, calipers or thickness gauges cannot be used to measure the cantilever and vertical sections of the traffic light pole. Ultrasonic thickness measurement is possible. The thickness of the steel plate should be tested using instruments to ensure it meets contractual requirements and national standards.

2. The thickness of the galvanized layer determines the corrosion resistance of the coated parts. A zinc layer thickness gauge can detect the thickness of the hot-dip galvanized layer on the light pole to ensure it meets national standards and the client's requirements.

3. Coating thickness is an important process parameter. In routine testing, the Taguchi method is commonly used to test coating adhesion, but sometimes it is difficult to control the coating thickness. Here, we recommend using electromagnetic induction measurement. A thickness gauge can accurately detect the coating thickness of the current product.

Phoebus specializes in producing high-quality octagonal traffic light poles. Our products are made of high-strength steel, precision bent, and hot-dip galvanized for corrosion protection. They feature a robust structure that is wind and pressure resistant, and an electrostatic powder-coated surface that is weather-resistant and wear-resistant. Custom sizes are available to suit various traffic light installation needs. Our craftsmanship is exquisite, and our quality control is rigorous.
