What is the price of 15 meters high solar street light

When purchasing lamps, buyers tend to be more focused on the quality of the lamps and lanterns, spend a lot of thoughts on the style or brightness, thus ignore the choice of the light pole. The same as the main part of street lamps, light pole if quality is bad, will cause a lot of problems, even

when purchasing a street lamp, buyers tend to be more focused on the quality of the lamps and lanterns, the style or the brightness to spend a lot of state of mind, so the choice of ignored the light pole. Street light as the main part of street lamp, if the quality of the light is bad, will cause a lot of problems, even buried safe hidden trouble in the future. Substandard poor corrosion resistance of the light, easy to rust, impact resistance is poor, poor appearance and waterproof effect. It not only bring inconvenience to daily use, but also greatly shorten the service life. In pursuit of greater profits, some unscrupulous businesses to mass produce inferior light pole. The buyer must open your eyes, carefully identify. When choosing high quality light, we must pay attention to these aspects. First, light plate steel with high strength, strong plasticity and good toughness, is now the most mainstream material manufacture light pole. High quality steel can even against nature, there are more than 12 level winds. There are good quality steel and poor quality of steel, because of production requirements do not conform to the national standard, so called non-standard steel. When unscrupulous street lamp manufacturers light, they are using a non-standard steel. However, non-standard steel thickness is very thin. In order to meet acceptance criteria, immoral manufacturers often through multiple injection plastics to increase the thickness of the light pole. In this way, the production of light pole easily shaking or under strong winds. To determine whether a lamppost conform to the standards of the most effective way to learn; Ndash weighing, if you don't know the specification and weight of the light pole, you'd better look around. If the weight is too light in the same specification, you can consider the standard. Second, the light pole welding welding is one of the important link of street light processing technology. Poor welding will ultimately lead to a lamppost fracture. Therefore, must be strict with light welding. Light pole welding need to machine and Labour. In general, automatic submerged arc welding welding is after the light pole winding machine, lamp post weld smooth evenly. In other areas, if welding machine can't operation, you will need to manually, it needs high technology. Observed, good welding surface is smooth, no obvious welding defects such as porosity, flash and bite. 3. Lamp light pole electroplating galvanized cold galvanized and hot dip galvanized, main is to prevent corrosion, prolong the service life of street lamps. Hot dip galvanized zinc layer, however, a few times thicker than the cold galvanizing, its corrosion resistance is several times higher than cold galvanizing. Learn to distinguish between cold galvanized and hot dip galvanized will create favorable conditions for you buy a street lamp. Cold galvanizing smooth and bright, the workpiece without zinc block and agglomerate. Hot dip galvanized is rough and the silver, the surface has a process line and a small amount of water droplets, especially at one end of the workpiece. 第四。 Light pole plastic spraying a streetlight coating in order to beautiful and prevent corrosion. Color of light pole is unqualified products. Therefore, ordinary street lamp manufacturers are through polishing processing before the coating, this coating uniformity, color is more pure. To understand the plant production process, you must be visiting the factory. Determine the quality of the light pole depends not only on the material, but also on technology. Safe and reliable high quality light pole, the minimum life of 25 years. When you buy a street, you must be carefully selected and examined. Select normal product, away from the immoral manufacturers.
