Technical Description:
Welding Technique
The entire rod should be free from any cracks, leaks, continuous blowholes, undercutting, etc., with smooth and even welds, no bumps or undulations, and no welding defects. A welding flaw detection report must be provided.
2. Appliance Door
a. Electric doors are cut using plasma cutting.
b. The electrical door and lamp body are seamlessly integrated, without welding a protruding platform at the door opening, ensuring high structural strength.
c. Features reasonable operating space; electrical installation accessories included inside the door.
d. The gap between the door and the rod should not exceed 1 millimeter, and it should have good waterproof performance.
e. Equipped with a specialized fastening system and excellent anti-theft features, the fixed bolts require a non-standard tool for opening.
f. Electric doors should have high interchangeability, with reasonable operating space inside, and provide 3% of electric door accessories.
g. A M8x30 bolt is securely welded in the lower left corner of the lamp pole work door, which is hot dipped galvanized together with the pole, for connecting the cable's PE wire.
3. Hot-Dip Galvanizing Process
The inner and outer surfaces should be treated with hot-dipped galvanizing to prevent corrosion, with a thickness of ≥75um meeting the GB—／T13912－92 standard. The design service life should not be less than 30 years. The zinc-plated surface should be smooth and aesthetically pleasing, with a consistent color. After the hammering test, it should not peel or flake off. A zinc coating inspection report is provided.
4. Powder Coating Process
Outdoor high-purity polyester powder coating should be used, with white color available upon customer request. The coating has stable quality, does not fade or peel off. It has strong adhesion, resists intense UV rays, and is suitable for lakeside cities and key saline areas. The designed lifespan exceeds 30 years, with a thickness of ≥80um, meeting ASTMD3359-83 standards. A coating inspection report is provided. Powder coating protection requirements: film thickness not less than 40um, strong adhesion, no peeling or flaking. The surface is flat and smooth with consistent color.
5. Design Capabilities
a. Provide a rod loading calculation based on the light pole design drawing, in accordance with the wind speed tolerance requirements.
b. The forming square steel used for the rod body must meet the corresponding Chinese standards in terms of strength and surface structure.
Seal the lamp post to prevent moisture from entering.
6. Verticality Inspection
After the lamp post is standing upright, use a theodolite to check the vertical alignment between the lamp post and the horizontal. The verticality should be less than or equal to 0.2%.
7. Rod Appearance
The design and dimensions meet requirements, with an overall elegant and generous appearance. The rod surface is smooth and consistent, with even coloration. The galvanized layer is smooth and flat, and the powder coating has strong adhesion without peeling.
All fixed bolts and nuts, etc., are made of stainless steel (except for anchor bolts and nuts).
9. The cable passage inside the pole is unobstructed, making it easy to thread cables. It has no sharp edges, burrs, teeth, or similar features to prevent damage to the cables.
10. Poles meet lightning protection and grounding requirements; environmental temperature: -15 to 50 degrees Celsius; wind speed: 60 m/s; seismic resistance: 8 grades; corrosion resistance: 30 years.
Categories and Application Scope:
Monitored poles, also known as camera light poles, are typically categorized into Y, T, and R types. 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 then coated with plastic. They are suitable for urban roads, expressways, elevated bridge intersections, or T-intersections.
1. Basic Structure: Traffic signal poles and sign posts should consist of a vertical post, a connecting flange, a shaped support arm, an installation flange, and pre-buried steel structure.
2. The upright or transverse brace is made of straight seam steel pipe or seamless steel pipe; the connection end of the upright and transverse brace uses a steel pipe identical to the transverse arm, with a welding reinforcing plate for protection. The upright is connected to the foundation with a flange and pre-buried bolt, with a welding reinforcing plate for protection. The connection method for the transverse brace to the upright end uses a flange connection, with additional welding reinforcing plate protection.
3. All welds on the uprights and their main components must meet the standard requirements, with a smooth and even surface. The welding should be flat, smooth, solid, and reliable, free from defects such as voids, slag, cold joints, and incomplete welds.
4. The poles and their main components are equipped with lightning protection. The non-electric metal parts of the lamps form an integral unit, connected to the grounding wire through grounding bolts on the housing.
5. Poles and their main components should be equipped with a reliable grounding device, with the grounding resistance not to exceed 10 ohms.
6. Wind resistance: 45 kg/m²/h.
7. Surface Treatment: Pickling and phosphatizing followed by hot-dipped galvanized spraying.
8. Traffic Signal Pole Shapes: Round, Conical, Variable Diameter, Square Tube, Frame.
9. Traffic Signal Pole Material: Generally made of Q235 steel pipe welding. Main Technical Parameters: Pole Height: 6000mm-7500mm; Arm Length: 2000mm-24000mm; Main Pole: Wall Thickness: 4mm-12mm; Crossbar: Wall Thickness: 2mm-8mm; Pole Surface: Hot-Dip Galvanized; Protection Grade: IP54.
