Technical properties krafton® 256.40 FRP Bridge Decking Plank

With its plank pattern, mounted with 1 cm of spacing, the krafton® 256.40 creates a rustic appearance as an FRP bridge deck.

The mounting with spacing automatically accommodates for the coefficient of expansion. Since all the planks are laid separately from one another, there is no need for an expansion joint.

The load capacity of the krafton® 256.40 FRP plank is relatively high, given its low height of only 40mm.
Please refer to the graphs and tables shown below for a visual representation.

Maximum span as a function of deflection requirement

Depending on the deflection requirement, krafton® 256.40 can handle virtually any span and not reach the maximum bending stress. In other words, like all planks, krafton® 256.40 can effortlessly form an FRP bridge deck with the required FRP planks load.
