The shaft is the most important part of the "body" of the garden light, which is as important as the human leg, so the shaft material used in the garden light must be good. The shaft of a general courtyard lamp has three materials: aluminum, cast iron, steel, etc. 1. Choose the garden light from the firmness Let's talk about aluminum first. We all know that aluminum has a low boiling point and strong flexibility, so it is easier to deform, so its firmness is worse than steel, and it is generally not recommended to be used in windy areas. The wall thickness of the steel material can be increased, the stability is high, the support force is strong, the wind resistance is up to 36km / s, and the earthquake resistance is above 8.8, so the steel material is more robust. 2. Choose the garden light from the price If you choose the courtyard lamp from the price, aluminum is complicated to make and the material cost is expensive, so the price of the aluminum courtyard lamp is 3-6 times higher than the price of the steel material. When making aluminum garden lights, first burn the liquid, and then use a special abrasive tool to change the liquid into a shape. In the middle, various patterns will be engraved on the aluminum rod. After it is dried, it is galvanized and sprayed. The steel material is just cut into the required conical plate with a steel plate through a shearing machine, and then rolled into a light pole at a time through a rolling machine, and then it is beautiful through welding, grinding and other processes, and is galvanized and sprayed after completion. The construction time and complexity of aluminum courtyard lamps are more than those of steel materials. This also means that the garden lights made of steel materials are relatively simple in style, while aluminum garden lights are expensive and not strong, but they are rich in style.
