If you are installing a chain link fence, get the order right first. Mark the fence line and gate openings, put in the terminal and line posts, fit the rails and fence fittings, then stretch and fasten the mesh. Gates are usually dealt with after the main structure is in place.
That sounds simple, and for a short straight run it often is. The trouble usually starts with something small: one post is slightly out of line, a fitting does not match the tube, or one section of mesh gets pulled harder than the rest. Once several metres of fence are already fixed, those small errors become expensive to undo.
What Should You Prepare Before Installing a Chain Link Fence?
There is no benefit in digging the first hole before you know exactly where the fence is going. A few checks on the ground and a quick look through the delivered parts can save a lot of time later.
Mark the Fence Line and Gate Openings
To begin with, anchor the following points: the start and end points, corners, changes in direction, and gate openings. Tie a string line between the start and end points. Use this as a reference when placing the intermediate posts.
Do not guess gate width from the drawing and leave it there. Check the real opening on site. A small pedestrian gate is fairly forgiving. A wide vehicle gate is not. Its posts carry more load, and a mistake in the opening often shows up only when you try to hang the gate.
Match the Mesh, Posts, Rails, and Fittings
A roll of mesh is only one part of a chain link fence. The Chain Link Fence system also needs posts, rails, tension bars, brace bands, tension bands, rail ends, caps, clips, fence ties, and gate hardware.
For the mesh itself, wire diameter options include 2.5, 3.0, 3.5, 4.0, and 4.5 mm. Mesh openings can be 40 × 40 mm, 50 × 50 mm, 60 × 60 mm, 75 × 75 mm, or 100 × 100 mm.
Just because it looks safer on paper, there’s no reason to go for a heavier specification. A combination of factors including fence height, site use, security requirements, gate arrangements and expected loads all need to be considered.
Prepare Tools and Foundation Materials
Get the basic tools together before work starts: measuring tape, string line, digging equipment, concrete or the specified footing material, spanners, pliers, cutting tools, and whatever equipment you plan to use for mesh tensioning.
Open the accessory cartons too. Installers tend to notice a missing post very quickly. A missing tension band or rail end is easier to overlook, yet that one small part can stop a whole section from being completed.
How Do You Set Chain Link Fence Posts Correctly?
The mesh gets most of the attention because it is what people see, but the posts decide whether the fence will end up straight. Once the rails are connected and the mesh is under tension, moving a post is no longer a small job.
Set Terminal, Corner, and Gate Posts First
Start with the posts that define the fence. Terminal posts, corner posts, and gate posts should go in before the intermediate line posts.
Common round post sizes include φ40, φ48, φ60, and φ75 mm, with wall thicknesses from 1.5 to 2.5 mm. The right size depends on the actual fence. A taller perimeter, a large gate, or a site exposed to higher loads may call for a different post than a basic boundary fence.
Bigger is not always the answer. What matters is whether the post works with the rails, mesh, gate, footing, and the rest of the system.
Align the Line Posts
With the main posts fixed, go back to the string line and set the line posts between them.
Check them as you work. Height and vertical alignment matter, but so does the way you measure the run. If every new post is positioned only from the previous one, small errors can slowly add up. By the time you reach the end, the whole line may have drifted.
Straight posts also make everything after this easier. Rails meet more cleanly, the mesh pulls more evenly, and installers spend less time forcing parts into place.
Allow the Foundations to Set
One mistake we still see on site is tensioning the mesh too soon.
Chain link fence tensioning puts sideways load on terminal and corner posts. If the footing has not developed enough strength, a post can move while the mesh is being pulled. Then you are trying to fix the post and the mesh at the same time.
There is no single curing period or foundation size that fits every job. Soil condition, post size, fence height, local rules, and project design all matter here.
How Do You Install Rails and Chain Link Fence Fittings?
When the posts are ready, the job starts to come together quite quickly. Rails form the supporting line, while the smaller fence fittings handle most of the actual connections.
Connect the Top Rails
Rail sizes such as φ32, φ40, and φ48 mm are commonly used with chain link systems. Fit them along the post line and look at the joints before everything is tightened.
Do not ignore a rail that sits a little high or twists at the end connection. It may seem minor before the mesh goes on. Once the mesh is tied to it, the uneven line becomes much easier to see.
Install Bands, Caps, Rail Ends, and Clips
A typical set of chain link fence fittings may include brace bands, tension bands, rail ends, loop caps, post caps, end rail clamps, line rail clamps, rail sleeves, fence ties, clips, hinges, bolts, and nuts.
They are not interchangeable bits of hardware. A tension band holds the tension bar at a terminal post. A rail sleeve joins two rail sections. Fence ties keep the mesh connected to the supporting frame. Caps close the open ends of the tubes.
This is why fitting size should be checked against the post and rail before shipment. If a band is wrong or a rail end does not fit, somebody on site usually ends up drilling, cutting, or waiting for replacement parts.
Prepare Gate Hardware Before Final Mesh Tensioning
Do not leave the gate until every metre of surrounding mesh is finished.
Check the hinges, latch, gate posts, stops, opening width, and ground clearance first. Single swing gates, double swing gates, and sliding gates all put different loads on the structure.
A wide gate, especially one used by vehicles, should be treated as part of the fence design from the start. It is not just an accessory added after the main run is complete.
How Do You Stretch and Secure Chain Link Mesh?
This is the stage where the fence starts to look finished. It is also where rushed work becomes obvious. The mesh needs enough tension to stay flat, but pulling harder is not always better.
Position the Mesh Before Tensioning
Roll the mesh out beside the fence and check the height, direction, and edge type before fixing the end.
Chain link mesh can be supplied as Twist & Twist, Twist & Knuckle, or Knuckle & Knuckle. A knuckled edge folds the wire ends back, giving a smoother finish. A twisted edge leaves a sharper termination and can be used where a stronger security deterrent is wanted.
Also check the roll height against the posts and rails now. Finding the wrong height before tensioning is inconvenient. Finding it after several bays are tied off is much worse.
Apply Tension Gradually
Run the tension bar through the end of the mesh and connect it to the terminal post with the correct tension bands.
Pull the mesh in stages. Keep an eye on the diamond openings instead of judging tension only by feel. If the diamonds start changing shape in one area while another section is still loose, stop and correct it.
For outdoor projects, a galvanized or PVC-coated Chain Link Fence gives you different options for the site and finish. Coating matters for corrosion resistance and appearance, but installation still comes back to the same point: mesh, posts, rails, and fittings have to suit each other.
Secure the Mesh to Posts and Rails
Once the tension looks even, fasten the mesh to the line posts and rails with the specified fence ties or clips.
Try to keep the fixing pattern steady along the run. Big random gaps between ties leave more room for the mesh to move and make a long fence look less tidy.
Before going on to the next section, walk back along what you have installed. Check clips, ties, rail joints, exposed wire ends, post position, and mesh tension. Five minutes here can save a much longer repair later.
What Common Chain Link Fence Installation Mistakes Should You Avoid?
Most bad installations are not caused by one huge mistake. More often, the same small error gets repeated until it becomes obvious across the finished fence.
Misaligned or Unstable Posts
Mesh cannot hide a poor post line. If the posts lean or wander, the rails follow them and the fence will show it.
Use fixed reference points and keep checking the line as posts are installed. Give the foundations enough time before applying mesh tension.
Loose or Over-Tensioned Mesh
Loose mesh will sag and move. Pull it too hard and you can distort the diamond pattern or drag a terminal post out of line.
The aim is even tension. If the mesh looks flat and the diamonds keep their shape, you are getting close. Do not keep pulling simply because the tensioning tool can still move.
Missing or Mismatched Fence Fittings
This one causes more delay than people expect.
A wrong band diameter, an unsuitable hinge, a missing rail end, or clips that do not fit the tube may cost very little compared with the fence itself. On an export project, though, replacing that part after the shipment arrives can take days or weeks.
Check the fence fittings together with the mesh, posts, rails, and gates before loading. It is a simple check and usually a cheap one.
When Should You Use Project Support?
A short, straight fence on easy ground is one thing. A long factory perimeter with several gates, elevation changes, barbed wire, or razor wire is a different job. At that point, installation starts well before the crew reaches the site.
Know When DIY Installation Is Enough
For a small boundary with simple ground and one basic gate, an experienced installer may not need much outside help.
Once the run gets longer or the design includes several gate types, different fence heights, security toppings, or difficult ground, it makes sense to work from drawings and a complete material schedule. BENDIN also provides project support for customers who need help checking specifications and installation details.
Match the Complete Fence System
BENDIN works with complete metal fencing packages, which is useful on jobs where the mesh, posts, rails, gates, and fence fittings all need to arrive ready to work together. The company has more than 30 years of production experience behind its current operation, a 15,000 m² production facility, 190+ employees, and more than 80 machines used for chain link weaving, wire mesh welding, laser cutting, PE coating, and powder coating.
The wider fencing solutions include 3D Fence, 2D Fence, Steel Tubular Fence, 358 Security Fence, Edge Protection Fence, Workshop Safety Fence, gates, and matching components. For a chain link project, the useful part is not simply having more products. It is being able to check the mesh, posts, rails, gates, fittings, and surface finish as one order before production is closed.
Confirm Service, Packing, and Installation Details Early
For a larger order, send the total fence length, height, gate dimensions, mesh specification, post and rail sizes, finish, and accessory requirements before production starts.
Packing deserves a quick check as well. Chain link mesh can be supplied in rolls with wooden pallet, bundle, or bulk packing. Posts may be loaded in bulk or placed on metal pallets. What works best depends on unloading conditions and how the installation crew plans to move material around the site.
If you already have project drawings, send them when you contact the project team. It is much easier to correct a post size or fitting list on a drawing than after the container has arrived.

FAQ
How deep should chain link fence posts be?
Post depth depends on fence height, soil, post size, wind load, and local installation rules. Terminal and gate posts often need stronger foundations because they take more load than normal line posts.
How far apart should chain link fence posts be?
Post spacing should follow the fence design, height, rail layout, and site conditions. Once a spacing has been specified for a straight run, keep it consistent unless the design requires a change.
Do you need a top rail on a chain link fence?
Many chain link fence systems use a top rail to connect the posts and support the upper part of the mesh. Some project designs use a different support arrangement, so follow the specified structure rather than assuming every fence is the same.
What fence fittings are needed for a chain link fence?
Common fence fittings include brace bands, tension bands, rail ends, loop caps, post caps, rail clamps, rail sleeves, fence ties, clips, gate hinges, bolts, and nuts. The exact list changes with the post, rail, gate, and security arrangement.
How tight should a chain link fence be?
The mesh should stay flat without obvious sagging, and the diamond openings should remain even. Too much tension can distort the mesh or move terminal posts, so check the mesh shape and post line while you pull rather than relying only on how tight it feels.
