1. Firmness, aluminum has a low boiling point and is flexible. It is easily deformed when exposed to high temperatures. It is less stable than steel. It is generally not recommended to use in windy areas. The wall thickness of steel materials 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 garden lamps, the production process of cast aluminum is complicated, the material cost is high, and the shape is peculiar. Therefore, it is normal for the price to be 3 to 6 times higher than the garden lamp of steel materials. In terms of styling, cast aluminum garden lights are not necessarily the most beautiful and unique, and the landscape garden lights made of steel materials are also very beautiful.
3. Workmanship, cast aluminum and cast iron work more complex than steel materials, here with aluminum as the topic of analysis. First, the aluminum is burned into a liquid, and then the liquid is transformed into a type by a special abrasive. In the middle, the aluminum rod is engraved with various patterns, and after being dried, galvanized and sprayed. More time and complexity than steel materials. The steel material is only cut into the required conical plates by the steel plate through the shearing machine, and then rolled into a lamp post by the coiling machine once, and then it is beautifully polished by welding, grinding, etc., and then galvanized and sprayed.
