Hot DIP Outdoor Single Arm LED Street Light Pole will undergo anti-corrosion treatment on the surface and inside and outside of the pole body after the pole is rolled and welded. The surface will be covered with a corrosion-resistant zinc layer to prevent rusting of the steel. Hot dip galvanizing is a method of anti-corrosion treatment for steel. The hot-dip galvanizing process involves immersing the processed street lamp poles, which have been degreased, pickled, impregnated, and dried, in a molten zinc solution at around 500 ℃ to attach a zinc layer to the surface of the steel parts, thus providing anti-corrosion protection. The thickness of the galvanized layer is usually above 75 μ m, making the lamp poles corrosion-resistant for more than 30 years.
