Typical Uses of HY-51-250-750


Industrial and Manufacturing Facilities

The HY-51-250-750 is widely used in industrial plants, including automobile manufacturing workshops, electronics factories, and machinery production facilities. Its high section modulus (up to 29.2 cm³/m at 1.2mm thickness) enables it to support heavy equipment, production lines, and storage racks, while its lightweight design reduces the building’s overall load. For example, it can be integrated into the floor systems of manufacturing hubs, where stability and load-bearing capacity are critical for operational safety.


Commercial and Mixed-Use Developments

Commercial malls, office buildings, and mixed-use complexes benefit from the HY-51-250-750’s versatility. It serves as an excellent floor bearing solution for multi-story commercial spaces, providing stable support for foot traffic, retail displays, and office equipment. Its compatibility with various interior finishes (e.g., concrete, flooring tiles) makes it a flexible choice for architects and designers.


Public and Transportation Infrastructure

Public projects such as airport terminals, and municipal buildings rely on the HY-51-250-750 for its structural reliability and long-term durability. Its ability to span large distances without compromising strength makes it ideal for open public spaces, while its resistance to wear and tear ensures performance in high-traffic environments. It has also been successfully applied in key infrastructure projects such as railway stations and urban transit hubs.

FAQ


What is the difference between the HY-51-250-750 and other floor bearing plate models?

The HY-51-250-750 is distinguished by its optimized 51-250-750 profile, which delivers a higher moment of inertia and section modulus relative to its weight. This makes it more efficient in load-bearing while reducing material consumption, compared to conventional models with similar thicknesses.

Can the HY-51-250-750 be used in seismic zones?

Yes. The product’s robust structural design and high ductility make it suitable for use in seismic zones. It can absorb and dissipate seismic energy, reducing the risk of structural damage during earthquakes. For projects in high-seismic-intensity areas, consult the manufacturer for customized reinforcement solutions.

How long is the lead time for the HY-51-250-750?

The standard lead time is 7-15 working days for bulk orders. For customized orders (e.g., special thicknesses or material treatments), the lead time may extend to 20-30 working days. Contact the manufacturer for exact delivery timelines based on your project schedule.

Does the manufacturer provide installation guidance?

Yes. The manufacturer offers detailed installation manuals, including step-by-step procedures, safety precautions, and technical requirements. On-site technical support can also be arranged for large or complex projects, ensuring proper installation and optimal performance.

Is the HY-51-250-750 environmentally friendly?

Absolutely. The product is made of recyclable steel, aligning with green construction trends. Its long service life (over 25 years with proper maintenance) reduces the need for frequent replacements, minimizing construction waste. Additionally, its lightweight design lowers transportation energy consumption during delivery.
