It is currently the most mainstream material for manufacturing light poles. When you buy street lights, you must choose them carefully and check them carefully. High-quality steel can even withstand strong winds above level 12 in nature.. Observed intently, a good welding process has a smooth surface without obvious welding defects such as pores, weld bumps, and undercuts. Therefore, the regular street lamp manufacturers have a polishing process before spraying, so that the spraying is uniform and the color is purer.
Street light poles of substandard quality have poor corrosion resistance, are easy to rust, have weak impact resistance, affect their appearance, and have poor waterproof effects. 2. However, the zinc layer of hot-dip galvanizing is dozens of times thicker than cold galvanizing, and its corrosion resistance is also dozens of times that of cold galvanizing. Buyers must keep their eyes open and distinguish carefully. Generally, the welding after rolling the pole is machine automatic submerged arc welding, machine welding, the pole body welding pattern is smooth and even. It will not only bring inconvenience to daily use, but also greatly shorten the service life.
To judge the quality of the light pole is not only the material but also the craftsmanship. In order Wholesale Road Lights Manufacturer to meet the acceptance criteria, unscrupulous manufacturers often increase the thickness of the light pole by spraying multiple times. This type of steel is called non-standard steel because the production requirements do not meet the national standards. In order to pursue greater profits, some unscrupulous companies produce inferior light poles in large quantities.
Galvanizing of street light poles The galvanizing of street lamp poles is mainly cold galvanizing and hot galvanizing. Under the same specifications, if the weight is too light, you can consider non-standard. Also as the main component of street lights, if the quality of the light pole is not good, it will cause many problems and even bury potential safety hazards in the future.
