the street light pole with hot galvanizing reason have?

with 6 meters of solar street light pole need high weight of solar panels, wind high torque, LED lights, and even some project need will be placed on the light pole heavy-duty battery. If the malfunction of the light pole may cause light pole distorted or broken or damage to property and personnel. Galvanized can effectively keep the light pole from corrosion, ensure the normal order of the light pole strength for 25 years, and effectively maintain its various components.

so what is the principle of hot dip galvanized, in order to prevent the light pole corrode? People who have studied the chemical should know & other; Special anode & throughout; The principle of. Zinc is more active than iron metal elements. When zinc - Iron complex ( Zinc - Iron compounds) Corrosion to form the electrodes, then keep in electronic will be transferred to the iron iron, thereby helping to zinc. Zinc in forming a fine layer of oxide layer in the air, protect the zinc from deep oxidation.

the key is clear: in the air, forming a kind of thin oxide, zinc to avoid further oxidation; In the electrolyte ( Rain water, sea water, river water, acid and alkali corrosion) , zinc plays a special anode effect, so in any case, the zinc will make iron from corrosion.
