Traffic Signal Pole Series
Product Categories and Application Scope
Signal poles, also known as traffic light poles, are generally available in types such as I-type, T-type, and F-type. Specific specifications can be custom-made according to customer requirements. Signal poles are commonly made from high-quality steel plates, processed into an octagonal or hexagonal shape by large bending machines, or assembled and welded from rectangular tubes. The surface is treated with hot-dip galvanizing for corrosion resistance and then spray-painted. They are suitable for urban roads, expressways, elevated bridge intersections, or T-intersections.
1) Traffic signal poles are installed using submerge arc lifting and welding.
2) Surface treatment: Hot dipped galvanized and powder coated.
3) Wind Resistance: 45 kg/m²/h.
4) Surface Treatment: Pickling and phosphating followed by hot-dip galvanizing and powder coating.
5) Welded flat, smooth, and robust
6) Shape: Equal Diameter, Conical, Variable Diameter
7) Basic Structure: Traffic signal poles and sign posts should consist of a vertical post, connecting flange, shaped support arm, mounting flange, and pre-buried steel structure.
8) The pole and its main components should be made of durable structures, constructed from materials capable of withstanding appropriate mechanical, electrical, and thermal stresses. Such materials and electrical components should be moisture-resistant, non-explosive, fire-retardant, or flame-retardant products.
9) All exposed metal surfaces of the poles and their main components should be protected with a hot-dip galvanized coating, which is even and has a thickness of not less than 55μm.
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) Allowable tolerance for the cross-sectional dimensions of the pole and its main components is ±3mm.
13) The allowable deviation of the tower axis 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 sizes of the poles and their main components should be consistent, and the truss tower should serve as an excellent guide and positioning function for the light bracket lifting.
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 sturdy 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 pores, slag, incomplete welds, and weld gaps.
18) Under conditions of reasonable wind load intensity, the deflection (rotational 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 form an integral unit, connected to the grounding wire via grounding bolts on the housing.
20) The protection grade of the pole and its main components'外壳 shall not be less than IP55, and the protection grade of the pole and its main components should meet the requirements of 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 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 foundation concrete strength 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-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 poles and their main components should be made of stainless steel and have their surfaces powder-coated.
24) The uprights are made of Φ159×6 seamless steel pipes; the connection ends (0.2m) between the uprights and cross supports use Φ89×4.5 seamless steel pipes, protected by a welding reinforcing plate (δ10 steel plate); the uprights are connected to the foundation with a flange and pre-buried bolts, also protected by a welding reinforcing plate (δ10 steel plate); the cross supports are connected to the upright ends with flanges and reinforced with welding reinforcing plates (δ10 steel plates); the centerline of the uprights is 5m from the roadside end of the cross supports. The cross supports are made of Φ89×4.5 seamless steel pipes and have 3 evenly welded vertical pipes using Φ60×4.5 steel pipes in the middle.
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 pits. The upper surface of the sign post foundation is at the same elevation as the road infrastructure nearby.
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 pole installation is complete,焊接base nut protection.
1. Basic Structure: Traffic signal posts and sign posts shall consist of a vertical post, connecting flange, shaped support arm, mounting flange, and pre-buried steel structure.
2. Straight seam steel pipes or seamless steel pipes are used for the upright or transverse bracing arms; the connection ends of the uprights to the transverse bracing arms are made with pipes identical to the transverse arms, protected by a reinforced welding plate. The uprights are connected to the foundation with flanges and pre-buried bolts, also protected by a reinforced welding plate. The transverse bracing arms are connected to the upright ends using flange connections, with additional protection from a reinforced welding plate.
3. All welding joints on the upright and its main components must meet the standard requirements, with a smooth and even surface. The welds should be flat, smooth, firm, and reliable, without any defects such as voids, slag, cold joints, or open joints.
4. The upright 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 via grounding bolts on the housing.
