Demarcation / Boundary Lining
For basic demarcation or boundary lining, it is suggested to to go with the most cost effective form of fencing which involve 14x14 barbed wire on either a 6 ft stone post or concrete post or a light MS Angle Post where 2 feet goes under the ground and 4 feet stays above the ground level.
The recommended distance between two fence posts in 10 feet but they can be placed as far apart as 20 feet to further save on cost. The basic pattern of the fence design is to go for 4 horizontal lines each at a distance of 1 feet from each other. Other popular designs include 5 horizontal and 2 diagonal lines or 6 horizontal lines and 6 vertical lines. Complete guide on how to install this type of fence system can be found here
