A stainless steel stanchion (10) is formed from a tubular element (12). Two pairs of opposed access apertures are punched in the tubular element (12). Two forming tools are located in the tubular element (12), each in alignment with one of the pairs of access apertures. The forming tools are then displaced by displacement tools which engage the forming tools via the access apertures. The displacement tools push the forming tools first one way and then the other to deform wall material in the region of the access apertures to form outwardly protruding lip formations (28) which define receiving apertures (14) for handrails (16). A base (20) and cap (18) are shrink fitted to the formed tubular member (12) to form the stanchion (10). As there is no heating or welding the stainless steel does not discolour. |
