The decking board is made from NTR AB-classified timber and is of high quality. The decking board has rounded edges and is planed on all four sides, making it comfortable to walk on. One side of the decking board is always slightly finer, so examine them before screwing them down to achieve the best possible result.
 
The maximum center-to-center distance (c/c measurement) for the joists is 600 mm. Since this decking board is 28 mm thick, you will get a very stable floor if you lay joists with this spacing.
 
The length of the screws used to fasten the decking boards should be at least 55 mm. Secure each decking board with two screws at every joist. At the ends, you can pre-drill to avoid splitting the board.
