General street lamp manufacturers

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. At the same time as the main part of street lamp, if the heigh quality is bad, will cause a lot of problems, even buried safe hidden trouble for the future. Quality is not qualified light pole difference of corrosion resistance, easy to rust, poor poor resistance to impact and beautiful effect, waterproof effect is poor. It not only bring inconvenience to daily use, but also greatly shorten the service life. Some unscrupulous companies in pursuit of greater profits, mass production of inferior light pole, buyers must polish eyes, careful resolution. When choosing high quality light pole, we must pay attention to these aspects.

in the first place, light pole plate steel with high strength, strong plasticity and good toughness, is currently the most mainstream materials to make light pole. High quality steel can even resist more than 12 level winds. Of course, also have good quality steel quality is poor. This steel is known as non-standard steel, because production requirements is not in conformity with the national standard. When unscrupulous street lamp manufacturers produce light pole, they use non-standard steel. However, non-standard steel thickness is relatively thin. In order to meet acceptance criteria, unscrupulous manufacturers often through multiple coating to increase the thickness of the light pole. This production of light pole under strong wind shake or deformation easily. Whether light pole conforms to the standard of the most effective method & ndash & ndash weighing, if you don't know the specification and weight of the light pole, you'd better compare the goods to three. Under the same specification, if the weight is too light, 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 human. In general, light pole rolling after welding is automatic submerged arc welding machine. The weld rod body smooth and even. For the rest of the local area, if welding machine can't operation, it must be done manually, this requires high technology. According to the observation, good welding surface is smooth, no obvious welding defects, such as porosity, flash and bite edge. 3. Light pole galvanized galvanized light pole mainly have cold galvanized and hot dip galvanized. Two methods of zinc is to prevent corrosion and prolong the service life of street lamps. Hot dip galvanized zinc layer, however, several dozen times thicker than the cold galvanizing, its corrosion resistance is also cold galvanized dozens of times. Learn to distinguish between cold galvanized and hot dip galvanized will buy street journey create favorable conditions for you. Cold galvanizing smooth and bright, the workpiece without zinc tumor and zinc block. Hot dip galvanizing is rough silver, the surface has process line and a few drops of nodules, especially at one end of the workpiece. Four. Light stick plastic spraying coating is beautiful and the purpose of the light pole to prevent corrosion. Coating color of lamps and lanterns is not qualified products. Therefore, normal street lamp manufacturers are through polishing processing before the coating, this coating evenly, color is more pure. Understanding the production process, a factory must be visiting the factory. Determine the quality of the light depends not only on material, also depends on the process. 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.
