Talking about the selection of road light poles

1. The street light pole is made of high-quality low carbon steel Q235. The silicon content of the steel is not higher than 0.04%. After one-time bending by a large bending machine, the straightness error does not exceed 0.05%. The wind resistance of the light pole is 36.9 meters. It is designed for level 11 or higher per second, and the seismic intensity is level 8. 2. The total height of the rod body is X meters, the upper diameter is Xmm, the lower diameter is Xmm, and the wall thickness is Xmm. There is a flange at the bottom of the light pole, and the distance between the installation holes of the flange is X, and it is installed on the foundation through anchor bolts. (X is the parameter set by the user, or configured by the company according to the conventional configuration) 3. The welding method of the lamp pole is automatic submerged arc welding, the welding is reliable, the surface is smooth, and there are no obvious welding defects such as porosity, welding flash, undercut, etc. Ultrasonic flaw detection Inspection, up to the welding GBl1345 Ⅱ standard requirements. 4. The anti-corrosion treatment of steel rod adopts internal and external hot-dip galvanizing. The galvanizing process goes through the processes of pickling, hot-dip galvanizing, water washing, phosphating, and passivation. And zinc tumor, peeling, spots, yin and yang surface and other defects exist, the thickness of the zinc layer is more than 86um, which meets the national standard GB/T13912-92, the adhesion of the galvanized layer meets the requirements of GB2694-88, and the anti-corrosion life is more than 30 years. 5. After hot-dip galvanizing, the lamp pole is electrostatically sprayed (color can be selected), and sanding is performed before spraying to increase the adhesion. During the spraying process, the curing time and temperature are strictly controlled to ensure that the plastic layer is uniform, smooth and free of pores. The thickness of the spray layer is ≥1Ooum, the adhesion reaches GB9286-880, the surface is smooth, and the hardness is ≥2H.
