Overview of Closed 500 Floor Deck

Closed 500 floor deck is a composite floor system widely used in modern construction, with a cross-sectional height of 500 mm. It features a closed-type profiled steel sheet design, providing both structural support and formwork functionality. Through optimized cross-sectional shape and material strength, this product achieves a balance between high load-bearing capacity and construction convenience, making it suitable for industrial and civil buildings with specific span and load requirements.

Product Structure and Features

1. Closed Cross-Section Design: The bottom of the steel sheet is closed, effectively reducing lateral pressure during concrete pouring, ensuring a flat floor surface, and enhancing shear resistance.

2. High-Strength Material: Made from hot-dip galvanized steel or aluminum-zinc coated steel, offering excellent corrosion resistance.

3. Rapid Construction: Eliminates the need for additional formwork support, serving directly as formwork, which can shorten the construction period by 30%.

4. Seismic Performance: Integrates with concrete to form a monolithic structure, improving the floor's impact resistance.

Construction Process and Precautions

1. Laying Stage: Fix the floor deck according to the design spacing (typically 600-1200 mm), ensuring tight interlocking between sheets.

2. Welding and Fixation: Use spot welding or stud connectors to achieve a secure connection with steel beams.

3. Concrete Pouring: Prefer self-compacting concrete to avoid uneven vibration due to the closed structure.

Application Scenarios and Advantages

• Industrial Plants: Suitable for workshops with heavy equipment, with a load-bearing capacity of up to 8 kN/m2 or more.

• Commercial Complexes: Meets spatial requirements and enables flexible layouts when combined with steel frame structures.

• Cost Efficiency: Reduces the use of formwork and support materials, lowering overall costs by 15%-20%.

Conclusion

With its structural stability, the Closed 500 floor deck has become a preferred solution in modern construction. In the future, as lightweight and green building practices evolve, its technological iterations will increasingly focus on integrating environmental sustainability and smart construction.
