Agricultural fencing is utility first. The right layout depends on what the fence has to contain, the ground it crosses and where the real pressure points are. There is no single post spacing or material list that suits every farm, paddock or field.
The animal and the land decide the fence
Sheep pushing through a low boundary, cattle leaning over a fence, horses avoiding barbed wire and a quiet field divider all put different loads on the system. Ground conditions matter too: wet ground, slopes, dips, corners and gateways can change the post and strainer layout.
Official fencing specifications use different spacing for mild-steel and high-tensile systems and tell installers to adjust for the ground. That matches how farmers actually work: use the specification as a framework, then build for the field in front of you.
Strainers take the tension; line posts support the run
Plan the ends, corners, gateways and major changes of direction first. These are the points that take the load and normally need heavier strainer posts and suitable bracing. Intermediate posts support the line between them.
For stock, farm and field fencing, compare the full Agricultural Fence Posts range rather than treating every post as interchangeable.
Stock wire, high tensile, rails and barbed wire solve different jobs
Stock Fencing & Agricultural Wire covers livestock and field-boundary wire. Standard mild-steel stock fencing is more flexible and needs less strain; high-tensile systems run tighter and may use wider intermediate-post spacing where the installation allows it.
For a visible timber system, use Post & Rail Fencing. Add barbed wire only where it suits the livestock, boundary and public-access situation.
Gateways are separate load points
Gate posts, hinges and latches take repeated movement that the normal fence line does not. Match the opening, gate and post together, then use suitable Field Gate Fittings.
Buy the system, not just the obvious item
For a post-and-wire job, start with the wire and Agricultural Fence Posts, then add strainers, fencing staples, gates and the required Fencing Tools. For the complete range, return to Agricultural Fencing Supplies.
