Characteristics of grid structure engineering Large span design: Grid structures can achieve large span spaces, reducing the need for internal support columns and providing an open usable. Lightweight and high strength: Using lightweight and high-strength materials such as steel or aluminum alloys, the structure has a low self-weight but strong load-bearing. High flexibility: Can be designed into various shapes according to needs, such as flat grid, curved grid, spherical grid, etc. Fast construction: Using prefabric components, on-site assembly, short construction period. Aesthetic and practical: The structure is light and beautiful, suitable for modern architectural styles. Good economy: High utilization rate, low overall cost.
