Technical properties krafton® 400.80 FRP Bridge Decking Plank

With its modest width of 400mm and its height of 80mm, the krafton® 400.80 is our most impressive powerhouse. This plank is used to create an FRP bridge deck that can handle, in addition to pedestrians and cyclists, a service vehicle weighing as much as 20 tons.

Please refer to the graphs and tables shown below for a visual representation.

Maximum span relative to deflection requirement

When a span is chosen in combination with a deflection requirement that is below the relevant lines in the graph, the krafton® 400.80 meets the requirements set for a bridge decking plank in accordance with the Dutch Building Decree for use as a cycle and pedestrian bridge deck. Depending on the deflection requirement, the krafton® 400.80 can handle almost any span and the maximum bending stress will not be reached. In other words, like all planks, krafton® 400.80 can effortlessly form an FRP bridge deck with the required FRP planks load.
