What kind of material is better for garden lights

The shaft is a very important part of the major components of the courtyard lamp, so what kind of material is the best to use on the courtyard lamp shaft? There are roughly three kinds of materials for the shaft of the courtyard lamp, one is the aluminum courtyard lamp. One is the iron courtyard lamp, and there is a common steel courtyard lamp. The three production processes are somewhat different, the grinding tools are different, the construction period is also different, the degree of complexity is also different, and of course the effect is also different. Let's analyze it mainly from the firmness, the price of courtyard lights, and the workmanship.
1
Robustness: Aluminum has a low boiling point, strong flexibility, and is easily deformed when encountering high temperatures. Compared with steel, it has a slightly weaker firmness. Generally not recommended for use in windy areas. The wall thickness of the steel material can be increased, the stability is high, the supporting force is strong, the wind resistance is up to 36km/s, and the earthquake resistance is above 8.8.

The price of courtyard lights; the production process of cast aluminum is complicated, the material cost is high, and the shape is peculiar. Therefore, the price is relatively 3 to 6 times higher than that of steel courtyard lights. In terms of shape, the cast aluminum courtyard lamp may not be the most beautiful and peculiar. The landscape courtyard lamp made of steel materials is also very beautiful.

Workmanship: The workmanship of cast aluminum and cast iron is much more complicated than that of steel materials. Here, aluminum is the subject of analysis. First, the aluminum is fired into a liquid, and then the liquid is transformed into a shape by a special abrasive tool. In the middle, various patterns are engraved on the aluminum rod, and after it is dried, it is galvanized and sprayed. The construction period and complexity are more than those of steel materials. The steel material is just cut into the required conical plates with a steel plate through a shearing machine, and then rolled into a light pole by a plate rolling machine, and then welded, polished and other processes are used to make it look beautiful. After completion, galvanized and sprayed.
Garden lights are ideal road lighting fixtures. With the improvement of people's lives and the continuous development of society, it will be widely used, so that the light given to the earth by the sun can illuminate humans at night.
