Aluminum alloy for light-pole

Cement, cast iron, steel, fiber glass reinforced plastics, etc. are the material for light-pole. The light-pole that made of cement has a low cost, and it no need to processed by surface treatment. However, cement light-pole is very heavy, a high transportation costs, expensive installation equipment and high risk are the weak side. At present, most of the light-pole is made of cast iron, this kind of light-pole has a low cost and a high intensity. However, cost iron light-pole will occurs severe corrosion during use, so it must be maintained regularly, and brings a high maintenance costs.
