<p>A snap fitting for linking decking elements has symmetrical grip flanges and grooves (10, 20) on the long edges of the elements. The flanges have two or more grip ridges (14) which engage corresponding grip grooves (24) inside the connecting grooves on adjacent elements. The grip flanges are split (15) to provide a spring effect. The decking elements have different profiled outer surfaces (O1, O2) and can be laid either way up. The elements are secured onto the support structure by threaded fasteners (M) set through the lower lips of the fitting grooves via countersunk holes.</p> |
