YX65-185-555

65mm depth×555mm width metal decking profile

Effective cover width: 555mm
Overall width of sheet: 1000mm
Length: Customizable
Thickness: 0.75mm-1.2mm
Material: Galvanized steel sheet, galvalume steel sheet

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.
