In modern information display and interaction scenarios, multi-screen systems have become the core technology for applications such as commercial displays, command and control, digital signage, and conference collaboration. The combination of multiple displays not only expands the visual boundaries but also poses unprecedented demands on the physical structure—the enclosure—that supports them. Unlike single-screen devices, multi-screen shells carry several times the weight, have a larger structural span, and are subjected to more complex forces. If deformation, loosening, or even collapse occurs during long-term operation, it will directly affect the display effect, device safety, and even user experience. Therefore, the material used for the enclosure's strength and stability is a key factor determining system reliability. High-strength metal materials, with their superior mechanical properties and durability, play an irreplaceable role in multi-screen enclosure construction, providing solid support for long-term stable operation.The structural challenges of multi-screen enclosures stem primarily from weight. The combined weight of multiple displays far exceeds that of ordinary electronic devices, especially in large video walls, curved displays, or outdoor advertising screens. If the enclosure material is not strong enough, simply increasing its thickness or volume will not only result in a bulky structure but may also cause sagging, warping, or cracking at the joints due to its own weight. High-strength metals, such as aerospace-grade aluminum alloys, stainless steel, or special alloys, possess excellent strength-to-weight ratios. They can withstand enormous loads in relatively lightweight structures, effectively distributing the weight of the screens and preventing localized stress concentration, ensuring the frame maintains its geometric stability under long-term load.Even more complex is the dynamic stress environment. Multi-screen systems are not only subjected to static loads but also to dynamic forces such as vibration during transport, installation adjustments, thermal expansion and contraction due to temperature changes, and even accidental human contact or minor impacts. These external forces are transmitted through the enclosure to the screens. If the structure is not rigid enough, even slight deformation can cause gaps, misalignment, or offset seams between screens, disrupting image continuity and aesthetics. High-strength metal materials possess excellent bending, torsional, and impact resistance, absorbing and dispersing external disturbances to maintain the overall structural rigidity and stability. Even under frequent movement or varying environmental conditions, the metal casing maintains its original shape, ensuring the screen remains precisely positioned.From a long-term durability perspective, the fatigue resistance of metal is crucial. A multi-screen system is not a temporary structure for short-term use; it needs to function reliably for years, even decades. During this period, the material will experience repeated stress cycles. Ordinary plastics or low-grade metals may crack or break due to fatigue. High-strength metals, however, undergo precise machining and heat treatment, resulting in a dense, uniform microstructure with excellent fatigue resistance. They maintain stable performance under long-term loads, resisting aging, deformation, and loss of elasticity, ensuring minimal maintenance and component replacement throughout the system's lifespan.Furthermore, metal provides a reliable foundation for functional integration in multi-screen systems. The casing often needs to incorporate features such as cooling vents, cable routing, mounting brackets, grounding terminals, and even electromagnetic shielding. High-strength metal can support these additional structures and, through precise CNC machining, achieve complex integrated features. For example, heat dissipation fins can be directly machined into the metal frame, improving efficiency and eliminating the risk of loosening from separate components. Grounding paths can be directly conducted through the metal body, enhancing electrical safety. This deep integration of functionality and structure further enhances overall system reliability.In terms of aesthetics and protection, metal casings also excel. Surface treatments such as anodizing, sandblasting, and electrocoating enhance corrosion resistance and fingerprint resistance, while also imparting a premium look and feel. Even in high-traffic public spaces like shopping malls, airports, and factories, the casing withstands daily wear and tear, maintaining a clean appearance.In summary, high-strength metal is not only the "skeleton" of the multi-screen shell, but also the guarantee of its long-term stable operation. With its inherent robustness, it silently supports visual display and information flow, ensuring clear presentation and safe operation.
