Floor deck-51 is a purpose designed trapezoidal composite flooring profile and is the most advanced composite decking in the region, It incorporates the specific floor decking required by designers, developers, engineers and builders, resulting in a revolutionary geometrical dimensions profile.



The Floor Deck-51 is a trapezium-shaped steel sheet that is an integral part of the composite steel deck floors. Steel Deck Flooring typically consists of 3 major elements: Floor Deck 51, concrete and light meshes to control cracking. The profiled steel deck acts as easy to install shuttering to contain the setting concrete.

Product Features

  • FLOOR DECK-51 should be kept dry during storage before it is used. It should be stacked clear off the ground with timber sleepers and covered to prevent water penetration into the bundles. If the bundles become wet during transportation or storage, the deck plates must be separated and wiped with a clean cloth as quickly as possible.
    When lifting the deck plates whilst loading or unloading or when lifting it onto the floor frame structure, care must be taken to prevent the bundles or loose pieces from dropping to the ground or hanging against the building.
Material Specifications :
• High tensile steel with minimum yield strength of 550Mpa and a minimum zinc coating mass of 270g/m².

Tolerances :
• FLOOR DECK-51 are produced within the following tolerances: 
     • Length : 10mm
     • Cover : 10mm
     • Thickness : 0.02mm

Embossments :
• Raised pigeon tail pattern embossments on each face of the web provides the mechanical connection between the steel and the hardened concrete.

Generally gaps are sealed with waterproof tape by sandwiching contraction joint materials between the abutting ends of the Floor Deck-51 sheet. If there is a sizeable gap, you may have to support the waterproof tape.
