In modern urban life, we can often see various types, different sizes, bright colors, and colorful outdoor digital signage. Many of them use aluminum alloys instead of traditional iron structures. So why the trend? Here are several ways in which it is more suitable than other options.   1. Lightweight design Compared with other traditional materials, iron, aluminum products are much lighter. This means that less manual and equipment can be used to complete the installation, and the installation cost is also significantly reduced.     2. Good corrosion resistance Because it is usually used outdoors, there is a clear difference between the two in terms of environmental factors. In contrast, aluminum products have strong oxidation resistance, are not easily affected by humid air, and have strong waterproof performance; At the same time, spraying technology can also be used to increase the surface hardness and improve the wear resistance. Therefore, the service life is longer in humid, rainy and other harsh environments.     3. Easy to maintain Aluminum alloy material has good plasticity and stampability, can be drilled, cut or bent into various shapes to adapt to different advertising needs. At the same time, it also facilitates daily maintenance work and saves human and material resources.     4. Environmental protection and safety Aluminum alloy is a non-toxic and easy to recycle material. Iron, on the other hand, can be a pollution problem and a safety hazard (such as rust). The selection of aluminum products can meet the requirements of environmental protection and ensure the safety of use.     In short, in the field of outdoor advertising machines, the choice of aluminum instead of iron has proved to be a better solution. It not only reduces equipment weight and installation costs, but also improves corrosion resistance and easy maintenance and renewal, and meets the requirements of modern society for health and environmental protection. https://www.cnlcdisplay.com/
