    These closed profile metal floor decks are designed with a rib height of 65mm, rib spacing of 185mm, and an effective cover width of 555mm. The closed profile structure creates a stronger bond with concrete, delivering high load capacity, reliable seismic performance, and better fire resistance than open profiles.

    Applications

    Closed profile metal floor decks are widely used in high-rise steel structures, industrial plants, shopping centers, airports, railway stations, stadiums, and other large-scale projects that require strength, fire safety, and efficient installation.

    Features
    • The closed profile design forms a strong bond with concrete, preventing slippage and ensuring long-term structural reliability.
    • High bending and shear resistance ensure a good load-bearing capacity, even in demanding projects.
    • Fire resistance is enhanced since the ribs are fully encased in concrete.
    • Multi-level operations during construction are possible, which helps shorten project timelines.
    • The flat underside has a clean finish, which makes additional ceiling work not necessary.
    • Compatible suspension systems allow easy installation and adjustment of pipes, conduits, and other building services.

    Dovetail re-entrant metal floor decks are a good option. They are lightweight yet strong, with high load-bearing and seismic performance. The flat underside provides a smooth surface, making it easier to attach suspended ceilings, electrical conduits, and other systems during construction.

    Closed profile metal floor decks are often used in these cases. Their fully enclosed profile design locks tightly with concrete, reducing the risk of steel and concrete separating under stress. This structure not only enhances overall strength but also offers improved fire resistance, making it a safer choice for large public buildings.

    Since the steel deck acts as permanent formwork, there’s no need for additional support structures. This simplifies installation, speeds up the concrete pour, and reduces labor on site. As a result, projects can be completed faster and with lower overall costs compared to traditional flooring methods.
