Welcome to the FRP Bridge decking website from krafton®

Technical properties krafton® 500.35 FRP Bridge Decking Plank

A special plank in our wide range! With its 35 mm height, this is the least strong plank in our FRP plank collection. Nevertheless, it is highly suitable for boardwalks, decks, terraces and balconies. This plank is also often used for roof and wall construction purposes!
krafton® 500.35 may not be as strong as our other FRP bridge decking planks in terms of load, but on the other hand, it is ideal for use in places where you can be sure that no vehicles will drive across it.

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

Maximum span relative to deflection requirement

krafton® 500.35 is not used as a bridge deck as often as our other planks. Due to its low height of 35 mm and fewer support legs, this plank will deflect relatively more with a larger span, and as such will be quicker to reach maximum bending stress. This plank is ideally more suitable for decking, train platforms and, for example, roof structures where 2kN is a requirement.
