Installing a chain link fence on flat ground is usually straightforward. The contractor marks the fence line, sets the posts, installs the framework and stretches the mesh between terminal posts. However, a sloping site changes several parts of that process.
Imagine a warehouse boundary that rises by 1.2 metres from one end to the other. Should the contractor install the fence in horizontal sections, creating a series of steps? Or should the mesh follow the natural slope of the ground?
Both methods are used in chain link fencing, but they produce different results. One can simplify the layout on uneven terrain, while the other can create a more continuous fence line with fewer gaps underneath.
For fencing contractors, industrial project buyers and distributors, choosing the right method before ordering materials can prevent unnecessary cutting, additional posts and installation delays.
This guide explains the differences between stepped and grade-following chain link fencing, including mesh installation, post positioning, bottom clearance, accessories and project costs. It also explains what information buyers should provide when requesting a quotation from a Chain Link Fence manufacturer.
What Happens When Chain Link Fence Meets Sloping Ground?
Chain link mesh is made from woven steel wires that form a series of diamond-shaped openings. Unlike rigid welded mesh panels, the woven structure can adjust its shape to follow certain changes in ground level.
This flexibility gives contractors more installation options. However, it does not mean that every slope can be handled in exactly the same way.
Before choosing an installation method, the contractor needs to understand three things:
- Ground profile: Is the slope gradual, steep, uneven or changing direction?
- Fence requirements: Must the top line remain consistent, or should the fence follow the natural ground?
- Bottom clearance: Can the project accept gaps beneath the mesh, or must the lower edge remain close to the ground?
These questions affect the fence layout, post positions and mesh quantities. A contractor who ignores the ground profile may receive the correct mesh specification but still struggle during installation.
What Is Stepped Chain Link Fence Installation?
Stepped installation divides a sloping fence line into separate sections. Each section follows a relatively level alignment, while the next section starts at a higher or lower elevation.
The finished fence looks similar to a staircase. The posts follow the changes in ground level, and the mesh sections connect at different heights.
Why do contractors choose the stepped method?
One reason is its straightforward layout. The contractor can divide the boundary into manageable sections and establish the post positions for each level.
This method can be useful where the terrain changes sharply or where the project requires horizontal fence sections rather than one continuous sloping line.
For example, a warehouse site may have a steep change in elevation near the rear boundary. Instead of forcing one long mesh run to follow every change, the contractor can divide the area into several sections.
However, the step height and section lengths need to match the site survey. Randomly changing post heights during installation can create an inconsistent top line and uneven panel connections.
The main disadvantage: gaps beneath the mesh
There is one issue buyers should consider before approving a stepped design.
When a horizontal fence section crosses sloping ground, a gap may appear beneath the lower edge of the mesh. The size of that gap depends on the ground profile and the selected step height.
For a general property boundary, a small gap may not create a major problem. However, a warehouse perimeter, animal enclosure or security boundary may require a much closer bottom clearance.
Those gaps can allow small animals, debris or unwanted access beneath the fence.
The contractor may need to consider additional ground preparation, a designed closing section, a concrete curb or another approved solution.
Do not assume that adding more mesh automatically solves the problem. The bottom detail should be included in the installation drawing before the material quantities are finalized.
Stepped installation requires attention at every transition
Each change in level affects the way the mesh terminates and connects to the supporting structure.
Depending on the fence system, the contractor may need additional terminal or corner post assemblies, tension bars and fittings at the transitions.
This can increase the number of components compared with a long, uninterrupted fence run.
For large projects, the BOQ should identify the number of level changes and the additional hardware required at those locations.
What Is Follow-the-Grade Installation?
Follow-the-grade installation, also called contoured or raked installation, allows the chain link mesh to follow the natural slope of the ground.
Instead of creating separate horizontal sections, the fence runs continuously along the rising or falling terrain.
The posts remain vertical. The mesh, top rail and supporting arrangement follow the planned fence alignment.
Because chain link fabric uses woven diamond openings, it can adjust along a suitable slope without requiring every section to remain horizontal.
Why does this method create a more continuous boundary?
The main advantage is the relationship between the mesh and the ground.
When the fence follows a consistent slope, the lower edge can remain closer to the terrain than it would under a stepped arrangement. This reduces the triangular openings that often appear beneath horizontal sections.
The finished fence also creates a continuous visual line along the property boundary.
This can be useful for industrial sites, farms, warehouses and long outdoor perimeters where the natural ground profile changes gradually.
However, the contractor still needs to control the mesh tension and terminal connections. A continuous slope does not remove the need for proper post positioning or suitable fittings.
What is a bias cut?
At a sloping fence termination, the top and bottom edges of the mesh may not meet a vertical terminal post at a right angle.
In that situation, the installer may need to make a bias cut. This means trimming the excess mesh along the slope so the tension bar can follow the required connection angle.
The installer must preserve the woven structure and leave enough wire for the specified termination detail. Cutting the wrong strands can weaken the mesh edge or make it difficult to secure the fabric properly.
For this reason, bias cutting requires careful measurement and the correct tools. It should follow the fence system’s installation instructions rather than an improvised cutting method.
Master Halco’s chain link installation instructions describe this hillside stretch method and explain how the installer positions the tension bar along the angled fabric edge.
For reference, see Master Halco Chain-Link Fence and Gate Installation Instructions.
Stepped vs Follow the Grade: Which Method Should You Choose?
The two methods solve different site conditions. A buyer should compare the ground profile, required bottom clearance and installation arrangement before selecting one.
| Comparison | Stepped Installation | Follow-the-Grade Installation |
|---|---|---|
| Fence Layout | Separate horizontal sections | Continuous slope along the ground |
| Appearance | Staircase-like profile | Continuous sloping profile |
| Ground Clearance | May create triangular gaps | Can follow the ground more closely |
| Post Arrangement | Post heights follow each step | Posts remain vertical along the sloping alignment |
| Mesh Adjustment | Separate sections and terminations | Mesh adjusts to the slope |
| Installation Work | Requires planned level changes and transition details | Requires careful tensioning and possible bias cutting |
| Material Planning | May need additional terminal posts and closing details | May need additional mesh length or special termination details |
| Typical Consideration | Steeper or irregular ground where steps suit the design | Gradual slopes where a continuous boundary is preferred |
There is no universal slope angle that automatically determines the correct method. The decision depends on the fence height, post spacing, mesh specification, ground profile and installation system.
For some projects, a combination of both methods may be more practical. The contractor could follow the grade along a gradual section and introduce a step where the terrain changes more sharply.
When Should You Choose Stepped Installation?
Stepped installation deserves consideration when the ground rises or falls sharply over a relatively short distance.
It can also suit sites where the contractor wants separate level sections or needs to coordinate the fence with existing retaining walls and terraced ground.
Consider the following applications:
Industrial properties with sharp changes in elevation
Some industrial sites contain cut-and-fill areas, retaining structures and access roads at different levels.
A stepped fence can follow these changes without requiring every mesh section to match the full ground slope.
However, the contractor should check the gap beneath each section and provide a suitable closing detail where the project requires it.
Terraced land and retaining structures
Where the landscape already uses terraces, a stepped fence may follow the existing layout more naturally.
Each fence section can align with its corresponding level, while terminal or corner assemblies support the changes in direction and elevation.
The designer should also check the retaining wall structure and the available space for post foundations.
Projects with clearly defined horizontal sections
Some commercial and infrastructure projects prefer level fence runs for appearance or coordination with other site elements.
In those situations, a stepped arrangement can provide a consistent horizontal line within each section.
The project team should still confirm whether the gaps below the mesh are acceptable.
When Should You Follow the Natural Ground Grade?
Following the grade is worth considering when the fence line has a relatively consistent slope and the project needs a continuous lower boundary.
Long agricultural and rural boundaries
Farms and rural properties often have long fence lines that cross natural slopes.
A contoured chain link system can follow the land without creating repeated step changes along the boundary.
This can also help maintain a closer fit between the mesh and the ground, which matters for animal containment.
Industrial and warehouse perimeters
Large industrial properties may have gradual elevation changes along roads, drainage channels and open storage areas.
Following the grade can create a more continuous perimeter and reduce the need for multiple stepped transitions.
However, the contractor must check the bottom clearance carefully. Areas with erosion, drainage channels or loose soil may need separate ground preparation.
Public and sports facilities
Sports fields and public recreation areas often need consistent boundary coverage.
A grade-following fence can reduce gaps beneath the mesh where the ground changes gradually.
The designer should still consider ball containment, pedestrian safety and the required fence height at each point.
What About a Site That Has Both Gentle and Steep Slopes?
Not every project needs one installation method across the entire perimeter.
Imagine a distribution centre with a relatively level front entrance, a gradual slope along the side boundary and a steep drop near the rear drainage area.
Using only a stepped design may create unnecessary gaps along the gradual section. Using only a grade-following design may require more complicated mesh terminations around the steep area.
A hybrid layout can address these differences.
The contractor could use:
- Standard installation along level ground.
- Follow-the-grade installation along gradual slopes.
- Stepped sections where the elevation changes sharply.
- Special closing details near drainage channels and retaining structures.
The benefit of a hybrid approach is that each section can follow the actual site conditions.
However, it requires a more detailed material schedule. The contractor must identify where the installation method changes and which posts, tension bars and mesh terminations each section requires.
Ground Survey: What Should Be Measured Before Ordering?
The installation method should come from a site survey rather than a rough estimate of the slope.
A drawing that only shows the total horizontal perimeter length does not explain the elevation changes along the fence route.
Before preparing the BOQ, the contractor should record the following information:
| Survey Item | Why It Matters |
|---|---|
| Total Fence Route | Establishes the overall material requirement |
| Ground Elevations | Shows how the terrain changes along the boundary |
| Slope Direction | Identifies rising and falling sections |
| Steep Transitions | Helps locate potential step changes and special posts |
| Drainage Routes | Identifies areas where water may wash out soil beneath the fence |
| Gate Locations | Helps establish level operating areas and opening clearances |
| Underground Services | Prevents conflicts during post excavation |
| Property Boundaries | Ensures post footings remain within the approved fence line |
A laser level, survey equipment or another suitable measuring method can help establish the elevation profile.
The survey should also identify the finished ground level, not just the existing surface. Planned excavation, filling and drainage work may change the final fence alignment.
Post Height and Foundation Requirements on Sloping Ground
Post selection becomes more complicated when the ground is not level.
For a grade-following installation, the vertical posts remain plumb while their exposed heights may vary along the slope. The contractor needs to account for the mesh position, top rail and required finished fence height.
For a stepped installation, the post heights follow the different elevation levels. Terminal and corner posts may also require additional fittings at the transitions.
Foundation design should reflect the actual soil and loading conditions. A post installed on a steep section may face different ground conditions from one on a flat area.
Before approving the post schedule, the responsible designer should review:
- Fence height and mesh configuration.
- Post section and wall thickness.
- Post spacing and terminal locations.
- Soil type and ground stability.
- Wind exposure and applicable structural loads.
- Required embedment and concrete footing dimensions.
- Drainage and possible soil erosion around posts.
Do not use one standard footing dimension for every slope. The final foundation arrangement should follow the project design and site conditions.
Top Rails, Bottom Tension Wires and Fence Fittings
A sloping chain link fence needs compatible supporting components.
In a conventional system, the top rail follows the designed fence alignment. Bottom tension wire, where specified, runs near the lower edge of the mesh and helps control the fabric between posts.
The terminal posts also use tension bars and tension bands to secure the mesh at the ends of each section.
On sloping ground, these details need additional attention.
For example, a bias-cut mesh termination requires a tension bar that follows the intended angle. A stepped section may need separate terminal connections at the transition.
Other accessories can include:
- Line posts and terminal posts.
- Corner posts and brace assemblies.
- Top rails and rail ends.
- Tension bars and tension bands.
- Bottom tension wire and clips.
- Post caps and fence ties.
- Gate posts and gate hardware.
The quantity of each component depends on the fence layout. A quotation based only on total fence length may not include enough fittings for a complicated slope.
For more information about the difference between tension bars and tension wires, see the Chain Link Fence Installation Guide.
Gate Openings Need a Separate Ground-Level Review
A fence can follow a slope successfully while the gate still creates a problem.
A swing gate needs enough clearance to open without hitting the ground. If the driveway rises or falls across the gate opening, the leaf may contact the surface during movement.
For this reason, gate areas should have a suitable ground profile. Industry installation guidance recommends keeping the area between gate posts as level as practical while maintaining the required drainage.
Sliding gates need a different review. The track or support arrangement must follow the gate manufacturer’s requirements so the gate can move without binding.
For a sloping property, the project team should decide whether to adjust the ground level around the entrance or use a gate system designed for the actual site conditions.
Do not calculate the gate height and bottom clearance from the fence roll dimensions alone. The opening, ground level and operating movement need their own drawing.
How Sloping Ground Affects the Total Project Cost
The cost difference between stepped and grade-following installation is not simply the price of the mesh.
Several other factors can change the final quotation:
| Cost Factor | Possible Effect |
|---|---|
| Additional Posts | Stepped transitions may require more terminal or corner assemblies |
| Mesh Cutting | Grade-following sections may require additional cutting and fitting work |
| Extra Fittings | More tension bars, bands and connections may be needed |
| Ground Preparation | Uneven terrain may require clearing, grading or drainage work |
| Foundation Work | Soil conditions and elevation changes can affect footing requirements |
| Installation Labour | Special alignment and termination work can increase site labour |
| Closing Details | Large gaps may require additional mesh, infill or civil work |
| Gate Adjustments | Sloping entrances may require additional ground preparation or special gate arrangements |
For a long perimeter, these costs can add up across several sections.
Therefore, the contractor should compare the complete installation scope rather than assume that the method using fewer mesh rolls will always cost less.
Chain Link Fence Specifications for Sloping Projects
The basic chain link product specification still matters, even when the installation takes place on uneven ground.
BDFENCE publishes the following product options for its Chain Link Fence range:
| Product Specification | Published Options |
|---|---|
| Wire Diameter | 2.5 / 3.0 / 3.5 / 4.0 / 4.5 mm |
| Mesh Opening | 40 × 40 / 50 × 50 / 60 × 60 / 75 × 75 / 100 × 100 mm |
| Roll Height | 1.2 / 1.5 / 1.8 / 2.0 / 2.4 / 2.8 / 3.0 m |
| Roll Length | 9 / 10 / 15 / 18 / 20 / 25 / 30 m |
| Top Rail | 32 / 40 / 48 mm diameter |
| Round Post Diameter | 40 / 48 / 60 / 75 mm |
| Post Wall Thickness | 1.5 / 1.8 / 2.0 / 2.5 mm |
| Edge Finish | Knuckled or Twisted |
These are published product options. The suitable configuration for a sloping site depends on the fence height, ground profile, post arrangement and approved design.
For example, a project using 2.0 mm wire and 50 × 50 mm mesh may require a different supporting system from one using 3.5 mm wire and 75 × 75 mm mesh.
Likewise, the required roll height and length should be confirmed against the planned installation method. A roll specification does not automatically determine the final quantity needed for a stepped or contoured perimeter.
Coating and Outdoor Durability
Sloping sites can create drainage and moisture conditions that affect fence components.
Water may collect around low sections, while exposed soil near the posts can move during heavy rain. These conditions deserve attention when selecting the surface treatment and planning the post foundations.
BDFENCE offers galvanized, PVC-coated and galvanized-plus-PVC chain link fence options.
Galvanizing provides zinc protection for the steel wire. PVC coating adds a polymer layer and a colored finish, commonly available in green and black.
However, the selected coating should match the actual site environment. The buyer should confirm the required zinc coating, finished wire diameter and treatment for the posts, rails and fittings.
During installation, workers should also protect the coating when cutting, tensioning and handling the mesh. Damaged areas should follow the approved repair procedure rather than receive an improvised treatment.
What Should You Send the Manufacturer Before Ordering?
A short enquiry saying “Chain Link Fence for a sloping site” does not provide enough information for an accurate material quotation.
The manufacturer needs to understand how the fence follows the terrain and where the installation method changes.
For a sloping project, prepare the following information:
- Site layout showing the complete fence route.
- Ground elevation survey or slope profile.
- Required fence height.
- Mesh opening and wire diameter.
- Proposed stepped or grade-following sections.
- Post locations and spacing requirements.
- Top rail and bottom tension wire details.
- Gate openings and ground conditions at entrances.
- Drainage routes and retaining wall locations.
- Surface treatment and color.
- Bill of quantities and delivery destination.
If the installation method has not been finalized, provide the survey information first. The contractor, designer and manufacturer can then review the mesh and supporting components against the proposed layout.
For a bulk order, the final material schedule should distinguish standard fence runs from special sections, step transitions and gate openings.

FAQ
Can chain link fence be installed on sloping ground?
Yes. Chain link mesh can follow suitable slopes because its woven structure allows the diamond openings to adjust. The contractor can also use stepped installation where the terrain or project design requires separate level sections.
What is the difference between stepped and grade-following chain link fence?
Stepped installation divides the fence into horizontal sections at different elevations. Grade-following installation allows the mesh and supporting arrangement to follow the natural slope of the ground.
Which method leaves fewer gaps beneath the fence?
Following the ground grade can keep the lower mesh edge closer to the terrain. Stepped installation may create triangular gaps beneath each section unless the contractor includes suitable ground preparation or closing details.
Does chain link mesh need to be cut when installed on a slope?
Some grade-following installations require a bias cut at the terminal connection so the tension bar fits the angled mesh edge. The installer should follow the selected fence system’s instructions and avoid cutting unnecessary mesh wires.
Should fence posts lean with the slope?
No. Posts are normally installed vertically, even when the fence follows a sloping ground line. Their exposed heights and connection positions should follow the approved fence layout.
Can I use the same gate on a sloping fence?
Not always. Swing gates and sliding gates need suitable ground clearance and operating space. The gate opening should receive a separate design review, including the ground profile and drainage.
What information is needed for a sloping-ground fence quotation?
Provide the site layout, ground elevation survey, fence height, mesh opening, wire diameter, post details, gate locations and the proposed installation method. This helps the manufacturer prepare a more accurate material schedule.
