Galvanized Light Pole Acceptance Standards

Phoebus hot-dip galvanized poles undergo a rigorous factory inspection, verifying appearance quality, process parameters, performance indicators, and technical parameters to ensure compliance with industry standards and order requirements. Let's take a look.

I. Material and Process Requirements

1. The main galvanized post is formed in one piece. The weld seams of the steel pole (Q235) must be smooth and flat. The flatness error between the raised part of the weld seam and the pole body should not exceed +1mm. (Method: Use a light pole thickness gauge to check the error between the raised part of the weld seam and the adjacent flat area.) The light pole is welded using automatic sub-arc welding, and the dye penetrant testing meets the requirements of the international welding standard GB/T3323-1989111. The light pole is fixed using through-bolts and set screws. (Visual inspection)

2. Light Pole Process. The anti-corrosion treatment is hot-dip galvanizing, requiring a smooth and aesthetically pleasing galvanized layer with consistent gloss. The pole should be free of wrinkles, drips, zinc nodules, peeling, spots, and uneven surfaces (visual inspection required). The zinc coating thickness should be at least 85µm (tested with a pole thickness gauge). The adhesion of the galvanized layer should meet GB2694-98 standards, guaranteeing no fading for 8 years. The pole's wind resistance is designed for 36.9 m/s. The pole's corrosion resistance lifespan should be greater than 20 years. (Relevant inspection reports from national institutions should be provided by the manufacturer.)

3. The pole's manufacturing process and acceptance standards should comply with national standards. The design coefficient is 1.8. The pole's design lifespan should be greater than 20 years. (Inspection reports provided by the manufacturer.)

4. The galvanized post design should facilitate wire connection. The handhole should be a backpack-style door (visual inspection required). The door must be flat and smooth, with a flatness error of no more than ±1mm (flatness checked with a pole testing instrument). Doors on identical poles should be interchangeable, meeting anti-theft and rainproof requirements. After the pole is cut, local reinforcement is applied to achieve a strength that is basically the same as the original integral pole. (Then, swap the small doors of two light poles to check their interchangeability.)

Phoebus hot-dip galvanized poles are made of high-quality Q235 steel, using hot-dip galvanizing technology. The zinc layer is uniform and thick, providing corrosion and rust resistance, and ensuring outdoor durability for over 20 years. Multiple quality inspections are conducted, with each step involving manual inspection. Our main products include street light poles and surveillance poles, and we support customization of height and diameter.
