Dubai Metro features no less than 60,000m2 of ComFlor® 80 composite floor decking.

The large corner curvature detail of ComFlor® 80 provides a very efficient profile. In conjunction with the higher grade of steel (450N/mm2), it ensures typical unpropped spans of 4.2m simply supported. Spans of 5.0m can be achieved in the continuous condition.

The achievement of such large spans means less structural steel usage and consequential savings in costs, providing more scope for architects and engineers in their design process.

The innovative profile design provides real ComFlor® 80 was used on 38 stations on “Tata Steel also provided a technical service benefits.
