Why choose galvanized steel? solar street light-litelsolar manufacturers

Steel is very easy to be oxidized to form red rust in the natural state. If it is not oiled, it can hardly meet the storage, transportation and indoor use. On the one hand, zinc can have better corrosion resistance than iron without passivation. After passivation, it can be used indoors for a long time without rusting. On the other hand, zinc on the steel surface can sacrifice itself to protect the steel, which can greatly prolong the time of red rust. In addition, chrome plating generally has longer corrosion resistance than zinc plating. This is also the role of steel corrosion resistance. Galvanizing is divided into hot-dip galvanizing and cold galvanizing. The main raw material is zinc ingot. Whether it is hot-dipped or cold-dipped, it can achieve the effect of color and luster, but the anti-corrosion effect of the two is very different. Cold galvanizing, also known as electro-galvanizing, is to use electrolytic equipment to deoil and pickle the workpiece into a solution of zinc salt, and connect the negative electrode of the electrolytic equipment; place a zinc plate on the opposite side of the workpiece to connect to the electrolytic equipment. Positive, turn on the power, and use the current to move from the positive to the negative direction, which will deposit a layer of zinc on the workpiece. With the development of the industry, hot-dip galvanized products have been used in many fields. The advantage of hot-dip galvanizing is that the anti-corrosion life is long, and it has always been a popular anti-corrosion treatment method to adapt to a wide range of environments. It is widely used in power towers, communication towers, railways, highway protection, street light poles, marine components, building steel structure components, substation auxiliary facilities, light industry, etc. The anti-corrosion period of hot-dip galvanizing is long, but the anti-corrosion period is different in different environments: 13 years in heavy industrial areas, 50 years in oceans, 104 years in suburbs, and 30 years in cities. The thickness of the alloy layer of hot-dip galvanizing mainly depends on the chemical composition such as the silicon content of the steel, the cross-sectional area of u200bu200bthe steel, the roughness of the steel surface, the temperature of the zinc pot, the dipping time, the cooling speed, and the cold rolling deformation. solar street light,solar street light manufacturer,high pole light,high pole light manufacturer,street light,street light manufacturer,street light,street light manufacturer,led street light,led street light manufacturer,street light pole,street light pole manufacturer,landscape light,landscape light manufacturer , Magnolia lanterns, Magnolia lanterns manufacturers, minority street lights Yangzhou Global Solar Technology Development Co., Ltd. is a manufacturer engaged in the production of outdoor road lighting, the main products are city circuit lights, solar street lights, high pole lights, led street lights, all kinds of special-shaped Landscape lights, magnolia lights, Chinese lights, street lights with ethnic characteristics, etc., welcome to visit our factory and consult and discuss business cooperation
