#iron posts

A less expensive alternative to round metal posts is black-painted steel angle-iron posts. These fence posts have a smaller cross-section than the round posts and are less likely to be heaved up by frost. However, angle-iron deer fence posts are not robust enough to serve as corner posts when the weight of a metal hexagrid fence, falling branches, snow, or deer are likely to create major stress. So in these cases, wood posts or round metal posts should be used on the corners.
