In modern construction, the rapid and precise installation of prefabricated walls is key to improving construction efficiency and ensuring the safety of structure. To this end, we have introduced an innovative System of Diagonal Bracing specifically designed to optimize the support process for prefabricated walls. The large strut bracing system, through its unique design, can easily and quickly support prefabricated walls. Compared to traditional bracing methods, it significantly reduces labor requirements, making the installation process more efficient.
