The different systems
There are several ways to attach decking boards without visible screws. For tropical wood decking boards, however, a fastener should always be used that is screwed from below. Lateral attachment is not suitable for very durable decking wood.
With the systems we offer at Betterwood, clips or strips are screwed onto the decking boards from below, which in turn are attached to the substructure. This solution offers significantly better structural wood protection than a concealed attachment for side-grooved decking boards.
