Road Safety Intelligent 3 color arrow traffic light

What are the materials of the Road Safety Intelligent 3 color arrow traffic light?
Due to the weather, there are some areas in China that are hot in summer and cold in winter.
The external conditions are very harsh, the principle of thermal expansion and contraction,
In northern cities in China, only aluminum traffic light housings can be used.
And the PC plastic case that can be used in the south,
Therefore, different materials of aluminum shell and plastic shell have appeared in China.
