With the improvement of people's living standards, people's visual senses are constantly improving. Therefore, in order to better attract the attention of consumers, businesses are also taking great pains and constantly creating new ways of publicity. For this reason, the form of advertising in the market is ever-changing, and the update frequency is super fast. All kinds of new advertising equipment are constantly pouring into the market, impacting people's visual nerves, and constantly igniting people's desire to buy.

In LCD digital signage display products, most of the shell materials of the products are aluminum profiles or sheet metal processes. Today we compare the advantages and disadvantages of aluminum profiles and sheet metal processes in digital signage applications.

First point : light weight. Since the density of aluminum is only about one-third of that of iron, under the same design, the weight of digital signage using aluminum profiles will be lighter, which is convenient for installation and transportation.

The second point : the anti-corrosion function. Generally speaking, the anti-corrosion function of aluminum profiles is due to the properties of the metal itself. Aluminum will combine with oxygen in the air to form a layer of aluminum oxide film, which will isolate the underlying metal from continuing to produce chemical reactions. After that, the surface will be painted to further enhance the anti-corrosion function of the aluminum profile. The anti-corrosion function of iron materials is completely provided by the surface painting. After a long time, the anti-corrosion performance will be reduced.

The third point: surface treatment performance. Aluminum profiles have good surface treatment properties and can accept a variety of surface treatment methods. The surface treatment of aluminum profiles is anodic alkaline frosted oxidation, which not only maintains the silvery white color of aluminum alloys, is light in weight, corrosion-resistant, high in structural strength, and scratch-resistant , easy to assemble, never rust, not easy to deform, high temperature and low temperature resistance, easy to disassemble and replace, quick to make and more environmentally friendly.

The fourth point: production accuracy. There is no heat welding in the production process of aluminum profiles, and the material has no deformation, so the assembly accuracy is high; while the traditional materials using heat welding will inevitably be deformed, which will affect the final assembly accuracy.

Of course, aluminum profiles also have disadvantages. For example, aluminum profiles are an expensive material because they require special manufacturing processes and surface treatment techniques. Aluminum profiles are a very useful and popular material. Although they have some disadvantages, this does not affect their status as digital signage. When choosing aluminum profiles, you need to weigh its advantages and disadvantages, and choose the most suitable application scenarios and needs.
