<p>A decking member (10) has opposite longitudinal edges (11, 12) which are shaped to form respective overlap and underlap portions. The edges are arranged to form a lap connection (24) when interconnecting the overlap portion (25) of one member (10<1>) with the underlap portion (26) of another member (10). In forming the lap connection, the overlap portion is arranged to engage the underlap portion under the application of downward pressure wherein, by that engagement, the members are operative to be caused to have a component of lateral movement on the application of continued downward pressure.</p> |
