Driven by the rapid development of the prefabricated building industry, the fiber cement board industry continues its strong growth momentum in 2025. As a key component of prefabricated non-removable floor slab systems, the demand for fiber cement boards maintains an average annual growth rate of over 15%. Notably, YJ non-removable formwork steel truss floor slabs, with their ease of installation and cost-effectiveness, have captured over 60% market share in projects such as transportation hubs and commercial complexes. The structural performance of these systems largely depends on the quality of the connection between the truss reinforcement and the fiber cement board; therefore, optimizing connector technology is a key factor driving industry development. This is especially important for any leading fiber cement interior wall panel supplier looking to expand its structural applications.
Case Study: Optimized Connector Application in a 31,100㎡ Project
The Shanhaiguan Service Area expansion project, with a total construction area of 31,100㎡, served as a practical verification site. This two-story frame structure had a tight schedule of only 7 months, requiring the installation of 800 YJ boards. Each slab (3.0m × 1.2m) consists of 12mm thick fiber cement board and 80mm high HRB400 truss reinforcement, secured by 15 optimized connectors arranged at specific intervals. We conducted numerous tests to evaluate the performance of these connectors.
Construction Efficiency Improvement: The application of these connectors significantly improved construction efficiency. The connection process between the truss reinforcement and fiber cement board reduced column-related work from 8 days to 3 days (a 62.5% efficiency improvement) and floor-related work from 12 days to 4 days (a 66.7% efficiency improvement). Overall, the lead time for related processes was reduced from 30 days to 15 days, a 50% efficiency improvement. This achievement was made possible by a simplified connection process-using self-tapping screws instead of repeatedly adjusting bolts, minimizing skilled welding, and reducing rework through increased adaptability, thereby reducing reliance on labor and simplifying on-site coordination.
2025 Outlook and Impact
Driven by the demand for prefabricated construction, the innovation focus of the fiber cement board industry in 2025 will be on "efficient connectivity" and "performance enhancement." The optimized connector technology presented in this article addresses long-standing issues such as installation complexity and poor adaptability.
It offers the following core advantages:
1) Ensuring structural safety by meeting key performance indicators such as tensile strength and deflection control;
2) Reducing critical path time by 50% to 66.7%, thereby ensuring on-time project delivery;
3) Providing a replicable connectivity solution for similar YJ panel systems, encouraging wider use of fiber cement boards in complex structures. As a forward-thinking fiber cement wall panel supplier, adapting to these technological changes is crucial. Looking ahead, connectivity technologies must evolve towards intelligence and lightweighting to keep pace with advancements in materials science and further drive the development of the prefabricated construction industry.
