Flooring structures and specially-adapted interlocking extruded aluminium plank components (1) for incorporation in them. The plank components (1) are characterised by a fixed point anchorage such as a retractable stud (3). Support and retention structure for the anchorage (3) is provided internally of the plank (1), with appropriate internal bracing and reinforcement (22,23,25). The anchorage structure is supported entirely by the plank, and does not need to project out behind the plank for securement to a vehicle underfloor. |
