Abstract
The invention provides a new fence system permitting the construction of privacy fences; perimeter fences; boundary fences and rail fences using a small number of different fence elements. These elements consist of a hollow elongated post/rail element of semi-octagonal transverse cross-section; an end cap for the element when used as a post; an L-shaped connecting bracket; a panel element and an end cap therefor; a clip for fastening panel elements to the rails; closure elements for the rails and posts that also locate and hold the panels when they are engaged in slots therein. The panels are provided near to their center with a plurality of spaced stiffening walls to resist buckling under heavy loads.

A post/rail element for a fence construction comprising an elongated hollow member of part-octagonal transverse cross-section having:
- an elongated base wall, two elongated intermediate walls, two elongated side walls parallel to one another, two elongated flange walls coplanar with one another, and two elongated spaced returned walls parallel with one another;
- respective longitudinal edges of the two intermediate walls having respective parallel junctions with the two longitudinal edges of the base wall;
- two respective longitudinal edges of the two parallel side walls having respective parallel junctions with the other two edges of the intermediate walls;
- two respective longitudinal edges of the two coplanar flange walls having respective parallel junctions with the other two edges of the side walls, and
- two respective longitudinal edges of the two parallel returned walls having respective parallel junctions with the other two edges of the flange walls.
