The steel structure manufacturing principle of outdoor LED display mainly includes the following aspects:   Structural design: According to the size and weight requirements of the LED display, design a suitable steel structure frame. The structural design needs to take into account the support and fixation of the various components of the display screen, and at the same time, it needs to meet the relevant safety and stability requirements.   Material selection: Choose weather-resistant steel suitable for outdoor environments, such as stainless steel or galvanized steel. These materials have good oxidation resistance and corrosion resistance, and can operate stably for a long time in an outdoor environment.   Welding and joining: Use welding or bolting to fasten the various parts of the steel frame together. Welding provides a stronger connection, while bolting facilitates disassembly and maintenance.   Strengthen support: In order to enhance the stability and load-bearing capacity of the structure, the steel structure frame usually adds components such as beams, longitudinal beams and support columns. These reinforced supports distribute weight and pressure, making the entire structure stronger and more stable.   Protection and coating: Steel structure frames need to be protected to improve weather resistance and corrosion resistance. Anti-rust treatment and coating can be carried out, so that the surface of the steel structure has better protection performance. Adding a circle of aluminum-plastic panel edging outside the steel structure will make the whole more beautiful, and also increase a certain degree of waterproofness.   Installation and adjustment: install the steel structure frame at the designated position, and adjust the levelness and verticality of the structure. Make sure led display is mounted smoothly, meets safety requirements, and is functioning properly.   Testing and acceptance: After the steel structure is fabricated, carry out necessary testing and acceptance. To ensure the stability and bearing capacity of the structure, while meeting the relevant quality standards and requirements.   Through the above steel structure production principles, it can provide stable support and fixation for the outdoor LED display to ensure its safe and stable operation in the outdoor environment. It is important to strictly follow the relevant standards and specifications during the production process to ensure the quality and reliability of the steel structure. It is recommended to seek the guidance and support of a professional steel structure fabrication company during the fabrication process.
