Square hollow section fence post - has T=section groove on each face and is formed by welding triple V=section externally to each corner

摘要

The fence uses square hollow section posts (5) with a triple 'V' section piece (6-9) welded externally to each corner. The legs of the attachments (6-9) are angled at right angles to their neighbours. A 'T' section groove is formed on each of the post faces, to locate cantilever rail spigots (4). Each spigot may terminate in a vertical plate (21) of a shallow 'U' shape in horizontal section which is secured by a bolt (22) which traverses a plate (21) hole to engage a square nut (23) located by a post groove (5).
