What is the difference between a SteelWall internal and a SteelWall external post?
An external post faces outwards, whereas an internal post faces inwards. As standard a square compound for instance would have four external posts, on in each of the corners. You will only require internal posts in the semi-permanent fencing system you are installing at some point turns back in on its self. In this case you want an internal, rather than external, post in order to keep the image presented to the public (those on the outside of the fencing system) consistent.
