Manufacturing method of light pole and matters needing attention in material selection

Street lamps are a kind of lamps that we can see everywhere outside. If there are street lamps, of course, there must be lamp poles. The production of this product is generally to flatten the two ends of the bent steel pipe billet, weld the bottom flange and ribs on one end, and plasma cutting. Make sure the kerf is straight. The lock seat is welded in the middle of the door, keeping it level. The product is galvanized according to the national standard to ensure that its surface is smooth, no color difference, and no sagging. The surface of the galvanized product is ground with a polishing wheel and then sprayed. The production of the new product is that the upper end of the spherical support shaft is consolidated with two steel plate discs, in which the support shaft transmits the force. Then put it into the upper light pole, connect and fix the steel plate disc (mostly stainless steel) at the lower end of the ball support shaft with the upper circumference, put the ball at the lower end of the ball support shaft into the inner spherical circle of the support seat, and then It is welded and fixed along the circumference, and then the support base is inserted into the lamp socket of the lower section from the upper end of the lamp socket of the lower section, and is welded and fixed on the circumference thereof.





Street lamp pole material: It is commonly made of high-quality steel plate, hot-dip galvanized, and then polished and sprayed. This type of product is very popular, but some people will use cold-rolled strip Q235 and Q195 because of the high price, which is not recommended for the government to use. Although hot-dip galvanizing is anti-corrosion, there will also be problems of rust and scars on the inner and outer walls. During routine maintenance, ultrasonic and magnetic particle inspection are used to detect the outer surface of high-pole lamps, which are also commonly used rust removal methods.


In the daily use of the product, maintenance is required. When there are rust marks on the street lamp pole, and there are cracks, it is reasonable to have a break without timely repair. Most of these products are older models. In the previous production, only a simple spray treatment was carried out. As the years of use are long, problems are prone to occur. And now the products of manufacturers are mostly galvanized, the technology is more advanced, and the service life is longer. Leakage of such products is a very dangerous thing, and there are many news reports on the hazards. Regarding such failures, most of the reasons are caused by the aging of the street lamps. In the daily maintenance, the relevant street lamp management departments should take the main responsibility. Another reason is that the rectifier is broken down, causing the product to be charged. If the leakage of electricity is found, it is necessary to report to the relevant departments in time.
