Chainlink Fencing Installation


Is the straining wire included with the mesh? Yes. On which side of the posts is the mesh connected? The outside, except for tennis courts or ball courts.

Roll Size and Height

Roll size come in many sizes starting at: 900mm, 1200mm and 1800mm all at 25M length.

What Type of Mesh

Is the mesh likely to be cut or are large numbers of people likely to lean on, play sport nearby or climb over the fence? These would all indicate a thicker wire diameter or heavier weight mesh should be chosen. Green is the most common colour for PVC coated mesh, other colours are available to order.

If mesh is not PVC coated it will have a galvanised finish which will protect the mesh from corrosion. This is silver/grey in appearance. The majority of chainlink has a 50mm mesh size, other sizes are available and 45mm is used commonly for tennis courts.

What Type of Posts?

There are a number of factors which you will need to take into account when choosing the materials for posts.

Concrete Posts

Concrete posts probably make the longest lasting fence but are prone to vehicle damage if used in drives and car parks, they are also reasonably heavy if access to the fence line is poor, unlike angle iron posts these have to be dug and concreted into the ground fully.

Angle Iron Posts

Angle iron posts have many advantages, they are durable, lightweight and concreting of intermediate angle iron stakes is optional depending on ground conditions, so the fence is quicker to erect. In coastal areas, to achieve the desired life, these posts may need to be galvanised finish.


Timber is another light weight low cost option for fence posts. Timber is particularly suited to lighter weight chainlink, again when using machine rounded intermediate stakes, these can be driven rather than concreted if desired, depending on ground conditions. Additional heights available up to 3.6m for use in tennis courts and security fencing.

Paint Finish to Metal Posts

Painted angle iron fencing posts are traditionally supplied in a one coat paint finish, applied at the factory. This is often relied upon as the only form of protection against the elements, so if you intend to use this type of post without further decoration, some rusting will occur almost immediately although the steel posts still seem to have a pretty good life.

To prevent further rusting, we recommend that the posts are given an additional paint finish following erection ideally prior to erection of the mesh.

Other Posts

Straining posts and struts must always be fully and firmly concreted into the ground as these form the anchor positions for the strained wire. The intermediate line posts can, except in the case of reinforced concrete, be driven into the ground. The ground conditions will dictate whether or not some concrete is required.

Straining Posts

These are placed at all ends, corners and changes of direction. A chainlink fence is constructed with two or three tensioned straining wires, which the mesh is attached to. It is imperative that the fence runs totally straight between these straining posts and the intermediate posts, which without the benefit of struts to support them, will be pulled out of upright and the fence will go slack.

Even in straight runs straining posts must be placed a maximum of 69m apart.

Connection to Line Posts

When using angle iron posts the straining wire is threaded through holes in the intermediate stakes and no additional materials are required. Although this can be done with concrete posts normally the line wires run across the face of the post.

Dependent on the type of post you will need to purchase either stirrup wire or a hair pin staple to connect the line wire to the line post. With timber posts, line wires would normally be stapled to the post with 30mm galvanised staples.

Joining Chainlink

Butt together the ends to be joined. Prepare the joint by carefully removing the last wire from one piece. To do this undo the ends and rotate which will cause the wire to emerge from the mesh. Now take this loose spiral of wire and wind it back into place, this time include the mesh to be joined on in the process.

Light Weight Angle Posts

Lighter weight straining posts are frequently used for 900mm high chainlink. For 900mm and 1200mm high chainlink light weight angle iron intermediate stakes are also available. When deciding whether these will be suitable for your application, you will need to consider the environment into which the fence is to be erected and also the distance between the straining posts.

It is normally accepted that the maximum distance permitted is 69m although in reality, distance between straining posts is usually a lot less, due to corners and changes of direction. It is not recommended that the light weight straining posts are used in situations where long runs of fencing are to be strained.

Straining Tight

There are two components in a chainlink fence that require to be tensioned. The strained line wires need to be tight. The chainlink or welded mesh which is applied to these line wires also needs to be tensioned and in all but the very light weight mesh, this needs to be achieved using a ratchet winch or straining device.

Clipping and Knuckling

At the edge of the roll of chainlink the wire that the mesh is made from is folded back on itself to form a finished edge that hopefully will not come unravelled. These are what we call the knuckles. The easiest way to fix the chainlink onto the straining wires is to open up knuckles at the edge of the roll every 300mm and hang the roll of chainlink onto the top line wire.

Once the chainlink is fully strained and you''re happy with its appearance, these can then be closed up with a pair of pliers. The middle and lower line wires are then clipped to the chainlink using netting clips either manually or using a clip gun.

In some instances, where the fence is likely to come under pressure from large dogs or footballs, the use of a thin galvanised wire to tie the chainlink to the straining wires is recommended rather than using the netting clips.


If you really cannot avoid going round a curve, there are a number of things you could do. The intermediate posts can be closed up so that they are between 1m and 2.5m apart depending on the severity of the radius. These posts should have additional concrete around their foundations and where it is feasible on an external radius, back supports for intermediate posts should be positioned behind the fence line.

Chainlink on Angle Iron Posts

These are installed by concreting in the strainer posts and simply baring a pilot hole and driving in the intermediate posts.

Strainer posts should be used at ends, corners, every 50m or at any change in direction off of a straight run. All strainer posts require struts, the number of depends on which type of strainer is being used. For a corner two are required, and an end, one. Struts are included when purchasing straining posts.

Line wires are then strung between the strainer posts using the ferrule winders that come with the strainer posts. The wire should be attached to the intermediate posts (at a maximum of 3m apart), by either threading through the holes provided or by using stirrup wires/tye wire.

The chainlink is attached by “knuckling” the top of the chainlink over the top line wire and clipping the chainlink to the other line wires. The bottom line wires should be clipped every 6” (approximately) and the middle every 1’ (approximately). It is then strained using the stretcher bars, threaded through then ends of the chainlink, these are attached to the posts by bolting them on using M8x30 bolts.

Chainlink on Concrete Posts

All of the concrete posts need to be concreted into the ground.

Line wires are strung between the strainer posts using eyebolts and attached to the intermediate posts using stirrup wires.

The chainlink is attached by “knuckling” the top of the chainlink over the top line wire and clipping the chainlink to the other two line wires. It is then strained using the stretcher bars threaded through the ends of the chainlink, these are attached to the posts by bolting them on using M8x25 or 30mm bolts and the angle cleats.
