The welding mode of lamp pole is automatic sub-arc welding, and the dye Detection Inspection meets the requirements of international standard GB / t3323-1989111. The lamp pole shall be fixed by threading nails and jacking screws. (visual inspection)

Solar Street Light pole workmanship

1. The anti-corrosion treatment is hot-dip galvanizing, and the surface of the galvanizing layer is required to be smooth and beautiful with consistent luster. There is no wrinkle, sagging, zinc tumor, peeling, spot, and defects on the internal and external surfaces. (the previous visual inspection) the thickness of the zinc layer is more than 85um (the thickness of the zinc layer is tested with a lamp post thickness gauge). The adhesion of the zinc layer shall meet the gb2694-98 standard to ensure that it will not fade for 8 years. The wind resistance of lamp-post shall be designed as per 36.9m/s. The anti-corrosion life of the lamp pole is more than 20 years. (the manufacturer shall provide relevant inspection reports of some national institutions)
2. The thickness of plastic spraying on the surface of lamp pole shall be no less than 100um, the adhesion shall reach gb9286-880, the surface shall be smooth: the hardness shall be no less than 2h, the outdoor weather-resistant material shall be adopted, and the plastic spraying material shall be all polyester plastic powder. (hardness of the material is indicated by indentation diameter)
3. The lamp pole process and acceptance standards shall be in accordance with the national standards. The design factor is 1.8. The design life of the lamp pole is more than 20 years. (inspection report provided by the manufacturer)
4. The lamp pole shall be designed to facilitate the wire penetration and the hand hole door shall be in the form of backpack door. (visual inspection) the pole door must be flat and smooth, and the flatness error with this pole shall not be greater than ± 1mm (the flatness shall be detected by the pole detector). The interchangeability between the same pole door and the door shall be good, so as to meet the requirements of anti-theft and rainproof. After the cutting of the bar and door, the local reinforcement treatment is carried out to basically achieve the strength of the original integral bar. (change the small doors of two poles to see interchangeability)
5. Appearance color: according to the color of the contract. (visual inspection)
