Steel tapered pole is usually used for solar energy. They are beautiful, stable, durable and easy to make various shapes. The processing technology is simple and the mechanical strength is high. The cross section shapes of commonly used tapered lamp poles are round, hexagon and octagon. Tapers are usually 1:90 and 1:100, and the wall thickness is generally 3-5mm according to the stress of the lamp pole. Since the operating environment of solar street lamps is outdoor, in order to prevent the corrosion of solar garden street lamp poles from reducing the structural strength, it is necessary to conduct anti-corrosion treatment on the lamp poles.
Anticorrosion is mainly to take preventive measures against corrosion causes. Corrosion protection shall prevent or mitigate the effects of humidity, high temperature, oxidation, chloride and other elements.
The common methods are as follows: hot dip galvanizing of solar street lamp poles: the process and method of immersing the pretreated parts in the molten zinc solution to form zinc and zinc iron alloy coatings on their surfaces. The thickness of the zinc layer is 65-90um. The zinc layer of galvanized parts shall be uniform, lubricated, and free of burrs, drips and excess lumps. The zinc layer shall be firmly combined with the steel bar, and the zinc layer shall not be peeled or raised. Plastic spraying treatment of solar street lamp pole: plastic spraying treatment shall be carried out after hot galvanizing. The sprayed powder shall be outdoor powder, and the coating shall not fall off or crack.
The plastic spraying treatment can improve the anti-corrosion performance of the steel pipe pole and greatly improve the aesthetic decoration of the solar street lamp pole. There are also various colors.
