The wind resistance of lamp pole is designed to be above M 36.9 m/s 11 and the seismic intensity is M 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. The bottom of the lamp pole is equipped with a flange, and the flange mounting hole spacing is? X. The flange is mounted on the base through the foot bolt. (X is a user-defined parameter, or is configured by the company as usual)
3. The welding mode of lamp pole is automatic submerged arc welding. The welding is reliable, the surface is smooth, and there are no obvious welding defects such as gas holes, welding nodules, undercut, etc. The ultrasonic flaw detection test meets the requirements of GBl1345 Class II standard.
4. Hot-dip galvanizing is used for steel rod anticorrosive treatment. The galvanizing process includes pickling, hot-dip galvanizing, water washing, phosphating and passivation. The surface of the galvanized layer is smooth and beautiful, with uniform luster. There are no wrinkles, falling, galvanizing tumors, peeling, spots, Yin and yang. The thickness of the galvanized layer is over 86um, which meets the national standard GB/T13912-92, and the adhesion of the galvanized layer is in line with GB2694-88. Requirements, anticorrosion life is longer than 30 years.
5. Electrostatic spraying of lamp pole after galvanizing (color is optional), grinding before spraying to increase adhesion, curing time and temperature are strictly controlled during spraying process to ensure uniform, smooth and non-porous plastic layer. The thickness of sprayed layer is more than 1 Ooum, the adhesion is GB9286-880, the surface is smooth, and the hardness is more than 2 H.
2. Lamps and lanterns:
