Traffic Signal Pole Series
Categories and Applicable Scope
Signal poles, also known as traffic light poles, are generally categorized into types such as 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 octagonal or hexagonal shapes using large bending machines, or assembled and welded from rectangular tubes. The surfaces are treated with hot-dipped galvanized corrosion protection and powder coating, making them suitable for urban roads, expressways, overpass intersections, or T-intersections.
1) Traffic signal poles are installed using submerged arc welding with suspended hoisting.
2) Hot-dip galvanized and powder-coated surface treatment
3) Wind Resistance: 45 kg/m²/h.
4) Surface Treatment: Pickling and phosphatizing followed by hot-dip galvanizing and powder coating.
5) Welded flat, smooth, and sturdy
6) Shape: Equal Diameter, Conical, Variable Diameter
7) Basic Structure: Traffic road signal poles, sign poles should be composed of upright poles, connecting flanges, shaped support arms, mounting flanges, and pre-buried steel structures.
8) The uprights and their main components should be durable structures, made of materials capable of withstanding appropriate mechanical, electrical, and thermal stresses. These materials and electrical components should be moisture-proof, non-igniting, 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 upright and its main components should meet the following requirements:
11) The height of the upright and its main components is allowed to deviate ±200mm.
12) The allowable deviation for the cross-sectional dimensions of the upright and its main components is ±3mm.
13) After installation, the allowable deviation of the tower axis displacement for the upright and its main components is ±5mm.
14) The vertical deviation of the upright and its main components is permitted to be 1/1000th of the tower's height.
15) The upright and its main components should be proportionate and consistent in size. The truss tower should serve as an effective guide and positioning aid 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 robust 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 (deflection value) at the top of the upright column and its main components should not be less than 1/200 of the height of the upright column 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 unit, connected to the grounding wire through grounding bolts on the housing.
20) The protection rating for the pole and its main components' housing shall not be less than IP55, and the protection rating of the pole and its main components should meet the requirements of outdoor usage environment.
21) The uprights and their main components should be equipped with a reliable grounding device, with the grounding resistance ≤ 10 ohms.
22) The type and dimensions of the upright and its main components should be determined based on the seismic intensity at the lighthouse installation site, wind load strength, geological conditions, and specific requirements proposed by the user. Specific installation drawings and construction requirements (including: the concrete strength of the foundation should not be lower than C20; a M24 anchor bolt should be pre-buried at the top of the foundation, with the bolt extending at least 100mm above the foundation level; the deviation in the pre-burial position of the anchor bolt should not exceed ±2mm; the location and specifications of the pre-buried steel pipe for the incoming cable, etc.) should be provided as required.
23) The outdoor control switch boxes for poles and their main components should be made of stainless steel and coated with plastic spray on their surfaces.
24) The uprights are made of Φ159×6 seamless steel pipes; the connection ends (0.2m) between the uprights and cross bracing arms are Φ89×4.5 seamless steel pipes, protected with a welded reinforcing plate (δ10 steel plate); the uprights are connected to the foundation with a flange and pre-buried bolts, also protected with a welded reinforcing plate (δ10 steel plate); the connection between the cross bracing arms and the upright ends uses flanges and is reinforced with a welded reinforcing plate (δ10 steel plate); the distance between the center axis of the upright and the end of the cross bracing arm nearest the road center is 5m. The cross bracing arms are made of Φ89×4.5 seamless steel pipes, with three evenly spaced vertical pipes焊接 in the middle, 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 bedding is laid in the pre-dug pit. The top 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.
The flag pole is installed, and the base nut is welded for protection.
