Bolt Body Corrosion Treatment: Entire inner and outer surfaces are hot-dipped galvanized with a zinc coating thickness of not less than 86μm, ensuring no rust for 30 years; the outer surface is coated with plastic powder with a layer thickness of not less than 95μm, maintaining color and adhesion for 5 years.

Technical Description:

Welding Technology

The entire rod should be free of any cracks, weld leaks, continuous blow holes, undercut, etc., with smooth and even weld seams, no bumps or undulations, and no welding defects. A welding flaw detection report must be provided.

2. Appliance Door

Electrical doors are plasma-cut.

b. The electrical door and lamp body are seamlessly integrated, without a welded boss 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 capabilities, the fixed bolts are opened with non-standard tools.

f. Electric doors should have high interchangeability, with reasonable operating space inside, and provide 3% of electric door accessories.

g. A securely welded M8×30 bolt is visible in the lower left corner inside the light pole access door, which is hot-dipped galvanized together with the light pole, for connecting the cable's PE wire.

3. Hot-Dip Galvanizing Process

The surface should be treated with hot-dipped galvanizing on both the inner and outer surfaces, with a thickness of ≥75μm, in compliance with GB/T 13912-92 standard. The design lifespan should not be less than 30 years. The zinc-plated surface should be smooth and aesthetically pleasing, with a consistent color. It should not peel or flake off after impact testing. A zinc coating inspection report is provided.

4. Powder Coating Process

Outdoor high-purity polyester powder coating should be used, with the color being white (subject to customer requirements). The plastic layer maintains stable quality, resists fading and peeling. It has strong adhesion, withstands intense ultraviolet radiation, and is suitable for cities along lakes and key saline areas. The design life exceeds 30 years, with a thickness of ≥80um, and complies with ASTM D3359-83 standards. A powder coating inspection report is provided. Powder coating protection requirements: film thickness not less than 40um, strong adhesion, no flaking or peeling. Surface is smooth and even, with consistent color.

5. Design Capabilities

a. Provide a rod load calculation based on the light pole design drawing, in compliance with the wind speed tolerance requirements.

b. The shaped square steel used for the rod body must meet the corresponding Chinese standards in terms of strength and surface structure.

C. 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 verticality between the lamp post and the horizontal plane, which should be less than or equal to 0.2%.

7. Rod appearance

The design and dimensions meet the requirements, with an overall elegant and generous appearance. The rod surface is smooth and uniform in color, with a zinc coating that is smooth and flat, and a powder coating that adheres strongly 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, easy to thread cables through, and free from sharp edges, burrs, teeth, or similar conditions to prevent damage to the cables.

10. The lamp post meets lightning protection and grounding requirements, 2. Environmental temperature: -15 to 50 degrees Celsius; wind speed: 60 m/s; seismic resistance: 8; corrosion resistance: 30 years.

Category and Applicability Range:

Monitors 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, shaped into an octagonal or hexagonal form by a large bending machine, or assembled and welded from rectangular tubes. The surface is treated with hot-dipped galvanized corrosion protection and then powder-coated. Suitable for urban roads, expressways, elevated bridge intersections, or T-junctions.

1. 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.

2. The upright or transverse support arm is made of straight seam steel pipe or seamless steel pipe; the connection end of the upright and transverse support arm uses steel pipe identical to the transverse arm, with a welding reinforcement plate for protection; the upright is connected to the foundation with a flange and pre-buried bolt, with a welding reinforcement plate for protection; the connection method between the transverse support arm and the upright end uses a flange connection, with a welding reinforcement plate for protection.

3. All welds on the uprights and their main components must meet the standard requirements, with a smooth and even surface, ensuring flat, smooth, and reliable welding with no voids, slag, loose welds, or open welds.

4. The upright posts 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.

5. The upright poles and their main components should be equipped with a reliable grounding device, with the grounding resistance not exceeding 10 ohms.

6. Wind resistance: 45 kg/m²/h.

7. Surface Treatment: Pickling and phosphatizing followed by hot galvanized and powder coating.

8. Traffic Signal Poles: 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
