The HY-51-342-1025 is a high-performance open/closed steel floor bearing plate tailored for large-span and heavy-load construction scenarios. As a core product of Wuxi Yataida—an enterprise with 4 automated production lines and an annual capacity of 600 million square meters for floor bearing plates—this model combines precision engineering with cost-effectiveness. It is crafted using advanced rolling technology, ensuring consistent dimensions and reliable mechanical performance for long-term use.
The HY-51-342-1025 stands out for its exceptional load-bearing efficiency. Its unique YX 51-342-1025 profile enhances structural rigidity, allowing it to span greater distances without compromising stability. Additionally, the product’s lightweight design reduces the overall building weight, while its easy-to-install features streamline construction schedules. It also adheres to strict quality control standards, with each unit inspected to ensure compliance with industry norms.

This floor bearing plate is ideal for industrial workshops and manufacturing plants requiring wide, unobstructed spaces. It has been successfully applied in projects similar to the tsmc and Changxin Storage facilities, where its high section of modulus enables it to support heavy machinery and equipment.
For logistics centers and large warehouses—such as Qingdao Chengtong New Energy Supply Chain Warehouse—the HY-51-342-1025 offers superior durability and load distribution. It can withstand the constant movement of forklifts and storage racks, while its corrosion-resistant surface ensures longevity in high-traffic environments.
The HY-51-342-1025 is also suitable for commercial malls, exhibition centers, and educational institutions. Its compatibility with various roof and wall systems makes it a flexible choice for architects, as seen in projects like the Tianjin Eco-City Kindergarten. It balances structural performance with aesthetic adaptability, fitting diverse design styles.

The HY-51-342-1025 features a trapezoidal cross-section that optimizes force distribution. Its expanded width options (1200mm/1250mm) allow for flexible coverage, while the interlocking connection method ensures structural integrity during installation and use. The product’s mechanical performance is enhanced by its precise moment of inertia, which minimizes deflection under load.
The maximum span depends on the selected thickness and load conditions. For standard industrial loads, the 1.5mm thickness variant—with a section of modulus of 32.4 cm³/m—can cover spans up to 4 meters. Our technical team can provide detailed span calculations based on your project’s specific load requirements.
The HY-51-342-1025 is manufactured using high-quality steel with inherent corrosion resistance. For harsh environments (e.g., coastal areas or chemical plants), we offer optional galvanized or painted finishes to enhance durability. These treatments extend the product’s service life and maintain its performance in corrosive conditions.
With our annual production capacity of 600 million square meters for floor bearing plates, we can efficiently fulfill orders. Standard orders have a lead time of 7-10 working days, while large-volume or customized orders may take 12-15 working days. We prioritize on-time delivery and can adjust schedules to meet urgent project deadlines.
