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® 500.40 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® 500.40 can handle almost any span and the maximum bending stress will not be reached. In other words, like all planks, krafton® 500.40 can also effortlessly form an FRP bridge deck with the required FRP planks load.
