Wind
In most cases when we buy solar street light poles we are concerned about being waterproof and corrosion resistant, but the wind is also a major factor in the durability of poles.
In some areas, there are often strong hurricane winds that can damage the fixtures of street lights and may tear cheap poles down the middle, in which case only steel or aluminum poles can withstand it.
It is also important to know how the poles are mounted. Usually, the poles are buried in the ground and fixed to a concrete foundation, so that they can better withstand the effects of the wind.
Corrosion
Corrosion is the real cause of damage to solar street light poles, as it can make the pole material brittle and cause the pole to deform or crumble. Solar street light poles are usually made of iron or steel, and these metals are prone to corrosion. Therefore, when purchasing a solar street light, make sure the pole has a good anti-corrosion coating to increase its durability.
High temperature
High temperatures can also affect the durability and performance of solar street lighting poles, especially in the summer. If you choose a cheap pole, plastic and iron poles that are not heat resistant may not stand up to the heat and risk collapsing.
It is therefore very important to choose a pole material that has good heat resistance. Some high-quality poles are often made of aluminum or carbon fiber, which are both highly heat resistant.
Coating
Galvanised coatings are effective in preventing the corrosion of solar street light poles. Galvanizing is a common anti-corrosion technique that prevents the corrosion of light poles by applying a zinc layer to the surface of the pole. Compared to cold dip galvanizing, hot dip galvanizing provides better corrosion protection and a thicker zinc coating.
Therefore, when purchasing solar street lights, you should ensure that the poles are hot-dipped galvanized and have a long corrosion life.
Rain
Rain can also affect the durability of solar street light poles. Rainwater contains several acids, such as sulphuric and chloric acid, which can erode the surface of the pole and cause it to corrode. These substances are particularly prone to erode iron and steel, so if you live in an area where there is a lot of rain, it is particularly important to choose a pole material that does not corrode easily.
Aluminum is a non-corrosive material that not only has high strength but can also withstand high winds and rainfall. Therefore, in areas where there is a lot of rain, choosing an aluminum pole can increase its durability.
