The iron box is a common box on the market. Its advantages are cheap price, good sealing, and easy to change the shape and structure. The disadvantages are also obvious. The weight of the iron box is too high, which is not easy to install and transport. In addition, its strength and precision are not enough, and it is easy to rust after a long time.

Die-casting aluminum cabinets are often used in rental LED displays. For example, Liancheng Falongyi and Longteng series LED rental screens are made of die-casting aluminum. It is characterized by high strength and precision, and light weight. More importantly, it can achieve seamless Stitching can have a better effect on the screen display.
The carbon fiber box design is ultra-thin, light in weight, good in strength, with a tensile strength of 1500kg, and the weight per square meter is only 9.4kg. With a fully modular design, maintenance is more convenient, and the 45-degree right-angle side can realize 90-degree splicing and installation of the screen body. At the same time, a non-transparent backplane is provided, which is suitable for large-area installation in the fields of sports venues and outdoor advertising lights.
The characteristics of the aluminum alloy box are that the density is relatively small, the strength is very high, and the heat dissipation is good, the shock absorption is good, and it can bear a certain load capacity.
