Traffic Signal Pole Series
Category and Applicable Range
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 on large bending machines, or assembled and welded from rectangular tubes. The surface is treated with hot-dipped galvanized corrosion protection and plastic coating, making them suitable for urban roads, expressways, elevated bridge intersections, or T-intersections.
1) Traffic signal poles are installed using submerged arc lifting and welding.
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) Smooth, even welding with reliable strength
6) Shape: Equal Diameter, Conical, Variable Diameter
7) Basic Structure: Traffic signal poles and sign posts should be composed of upright posts, connecting flanges, shaped support arms, mounting flanges, and pre-buried steel structures.
8) The poles and their main components should be made of durable structures, composed 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-dip galvanized coating, which should be even and not less than 55μm in thickness.
10) The quality of assembly for the pole 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) 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 height.
15) The dimensions of the poles and their main components should be coordinated and consistent. The truss tower should serve as a good guide and positioning function for the lighting bracket's lifting and lowering.
16) The connection 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 should meet the standard requirements, with a smooth and even surface, free of defects such as voids, slag, incomplete welding, and open joints.
18) Under conditions of reasonable wind load intensity, the displacement (deflection value) at the top of the upright and its main components should not be less than 1/200 of the height of the upright 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 of the pole and its main components' housing should not be less than IP55, and the protection rating of the pole and its main components should meet the requirements for outdoor usage environments.
21) The poles 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 pole and its main components' foundations should be determined based on the seismic intensity at the lighthouse installation site, wind load strength, geological conditions, and specific requirements from the customer. Detailed installation drawings and construction requirements should be provided as requested (specifically 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 of the pre-buried 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 the uprights 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) of the uprights to the transverse support arms are Φ89×4.5 seamless steel pipes, protected with a welding reinforcing plate (δ10 steel plate); the uprights are connected to the foundation with a flange and pre-buried bolts, also protected with a welding reinforcing plate (δ10 steel plate); the transverse support arms are connected to the upright ends with flanges and are reinforced with welding reinforcing plates (δ10 steel plate); the distance between the central axis of the upright and the end of the transverse support arm nearest the road center is 5 meters. The transverse support arms are made of Φ89×4.5 seamless steel pipes; and three vertical pipes are evenly welded in the middle of the transverse support arms, using Φ60×4.5 steel pipes.
25) Overall hot-dipped galvanized flag pole.
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 post foundation is at the same elevation as the road infrastructure nearby the post.
27) When the area of the installation sign in compliance with the national standards does not exceed 4.5 square meters, its wind resistance is 8 grades.
After the sign pole is installed,焊接 the base nut protector.
