Traffic Signal Pole Series

Categories and Application Scope

Signal poles, also known as traffic light poles, are generally categorized into Type, T-Type, and F-Type. Specific specifications can be customized according to customer requirements. Signal poles are commonly made from high-quality steel plates, processed into an octagonal or hexagonal shape using large bending machines, or assembled and welded from rectangular tubes. The surface is treated with hot-dipped galvanizing for corrosion resistance and coated with plastic for the exterior. They are suitable for urban roads, expressways, elevated bridge intersections, or T-intersections.

1) Traffic signal poles are installed using submerged arc welding.

2) Hot-dip galvanized and powder-coated surface treatment

3) Wind resistance: 45 kg/m²/h.

4) Surface Treatment: Acid pickling and phosphatizing followed by hot-dip galvanizing and powder coating.

5) Welded flat, smooth, and sturdy

6) Shapes: Equal Diameter, Conical, Variable Diameter

7) Basic Structure: Traffic signal poles and sign posts shall consist of a vertical pole, connecting flange, shaped support arm, mounting flange, and pre-buried steel structure.

8) The poles and their main components should be made of durable structures, composed of materials capable of withstanding suitable mechanical, electrical, and thermal stresses. These materials and electrical components should be moisture-proof, non-explosive, fire-resistant, or flame-retardant products.

9) All exposed metal surfaces of the upright and its main components should be protected with a hot-dipped galvanized coating, which should be even and not less than 55μm in thickness.

10) The quality of assembly for the uprights and their main structural components should meet the following requirements:

11) The height deviation for the pole and its main components is permitted ±200mm.

12) Allowable deviation for the cross-sectional dimensions of the pole and its main components is ±3mm.

13) The allowable deviation for the tower axis displacement after the installation of the pole and its main components is ±5mm.

14) The vertical deviation of the upright and its main components is allowed to be 1/1000 of the tower's height.

15) The upright and its main components should be dimensionally coordinated, and the truss tower should serve as a good guide and positioning function for the lighting bracket's lifting and lowering.

16) The connecting bolts for steel structures should be simple and uniform, with M16 as the preferred specification. The joints should have anti-loosening measures and be secure and reliable.

17) All welds on the upright and its main components must meet the standard requirements, with a smooth and even surface, free of defects such as pores, slag, incomplete welding, and gaps.

18) Under conditions of reasonable wind load intensity, the deflection (value of deflection) at the top of the upright post and its main components should be no less than 1/200 of the height of the upright post and its main components.

19) The poles and their main components are equipped with lightning protection. The non-electric metal parts of the lighting fixtures form an integral structure, connected to the grounding wire via grounding bolts on the housing.

20) The protection grade of the pole and its main components' housing shall not be less than IP55, and the protection grade of the pole and its main components should meet the requirements for outdoor usage environments.

21) The upright and its main components should be equipped with a reliable grounding device, with the grounding resistance ≤ 10 ohms.

22) The type and dimensions of the pole and its main components' foundations should be determined based on the seismic intensity at the lighthouse installation location, wind load intensity, geological conditions, and specific requirements provided by the customer. Detailed installation drawings and construction requirements should be provided as requested (specifically including: the concrete strength of the foundation should not be less than C20; an M24 anchor bolt should be pre-buried at the top of the foundation, with the bolt protruding at least 100mm above the foundation level; the deviation in the pre-burial position of the bolt should not exceed ±2mm; the location and specifications of the pre-buried steel pipe for the incoming cable).

23) The outdoor control switch boxes for uprights and their main components should be made of stainless steel, with the surface being coated with plastic.

24) The uprights are made of Φ159×6 seamless steel pipes; the connection ends (0.2m) of the uprights to the transverse brackets are Φ89×4.5 seamless steel pipes, protected with a welding reinforcement plate (δ10 steel plate); the uprights are connected to the foundation with a flange and pre-buried bolts, also protected with a welding reinforcement plate (δ10 steel plate); the transverse brackets are connected to the upright ends with flanges and are reinforced with welding reinforcement plates (δ10 steel plate); the centerline of the uprights is 5m away from the end of the transverse bracket nearest the road center. The transverse brackets are made of Φ89×4.5 seamless steel pipes; and three vertical pipes are evenly welded in the middle of the transverse brackets, using Φ60×4.5 steel pipes.

25) The flag pole is fully hot-dipped galvanized.

26) During construction, the foundation is cast on-site. Before casting, a 20CM thick sand cushion layer is laid in the pre-dug pit. The upper surface of the sign pole foundation is at the same elevation as the road infrastructure nearby the pole.

27) Signs installed in compliance with national standards, with an area not exceeding 4.5 square meters, have a wind resistance of 8 levels.

After the sign post is installed,焊接 the base nut protector.
