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. It is generally not recommended to 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.
2. 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.
