krafton® 256.40 FRP bridge decking plank
Appearances count! A span using 256.40 FRP bridge decking planks has the appearance of a wooden bridge with plank decking, since both sides of the plank are straight. During assembly, a joint between the FRP bridge decking elements is automatically created. This makes the plank one of a kind. The krafton® 256.40 FRP bridge decking planks are separated by a 10mm joint, allowing for easy drainage of rainwater and quicker drying of the FRP bridge deck.
In other words, installation of an expansion joint is not necessary.

The krafton® 256.40 plank has an ECI value of €0.92 m1 which converts to €3.59 m2, for a service life of 100 years. In comparison with a bridge deck made of wood, this is 63.9% lower, were a wooden deck must be replaced every 20 years (based on the EPD product card Footbridge (wood), category 3). In comparison with a bridge deck made of steel walking grids, this is 85.2% lower, were the steel walking grid needs to be replaced every 50 years (based on the EPD product card Walking grid; steel, galvanized and coated, category 3).
Technical properties krafton® 256.40 FRP bridge decking plank
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.
