Chainwire: Top Rail

Our Chainwire Top Rail fencing solutions provide added strength, stability and durability for sites that need a more secure and structured fence system. By installing a Top Rail along the upper section of the fence, your Chainwire Top Rail system gains extra support, helping maintain tension, reduce sagging and improve overall lifespan. This option is ideal for commercial, industrial, sporting and high traffic environments exposed to greater pressure, impact or long term wear.

Manufactured using high quality galvanised steel materials, our systems are built to withstand harsh Australian conditions while delivering long lasting performance. Whether you need a new installation or an upgrade to an existing chainwire fence, our team can provide customised Chainwire Top Rail solutions in a range of fence heights, rail sizes and configurations, with Top Rail fencing systems designed to enhance security, structural strength and professional appearance.

Why a Top Rail Makes a Difference
Without a Top Rail, a chainwire fence relies entirely on the tension of the mesh and the strength of the posts to hold its shape over time. In high-traffic or exposed environments, that is often not enough. Fences without a Top Rail are more susceptible to sagging along the upper section, bowing under pressure, and losing tension after years of use.


Adding a Top Rail changes that. By running a solid horizontal rail along the top of the fence line, the entire structure becomes more rigid, more resistant to impact, and far less likely to shift or deform over time. The result is a fence that stays upright, stays tight, and continues to do its job years longer than an unsupported installation.

Where Chainwire Top Rail Fencing Is Commonly Used
Chainwire Top Rail fencing is a practical choice across a wide range of applications. Some of the most common include:

  • Sporting facilities and recreation areas where fencing is regularly impacted by balls, equipment, or high foot traffic

  • Construction and building sites where temporary or permanent perimeter fencing needs to withstand daily wear

  • Industrial and warehousing facilities where vehicle movements and equipment can place stress on fence lines

  • Schools and childcare centres where long fence runs need to stay tight, safe, and visually consistent over many years

  • Commercial developments and car parks where a clean, professional fence appearance matters alongside structural reliability

  • Government and council infrastructure where fencing must meet strict performance and compliance standards

New Installation or Upgrade?
A major benefit of the Chainwire Top Rail system is its versatility, performing effectively as a fresh installation or as an enhancement to an existing structure. For fences currently experiencing sagging, loosening, or wear along the upper section, integrating a Top Rail provides a more economical alternative to a complete replacement.
To determine the best path forward for your property, our specialists can evaluate your current fencing to see if a Top Rail retrofit is suitable or if a new installation would offer superior long-term value.

amazing work by the team at Longain Fencing - we had Colourbond and chain link fencing installed and had a great experience. Great communication, superb quality, and friendly efficient workers.

Steven
The materials are excellent quality as I wanted, communication was smooth throughout, and the installation process was handled very professionally. I am extremely satisfied with the final result and would highly recommend this company.
Brad
I had a PVC chain fence installed by Richard (Longain). His team arrived on time as promised and finished the job over 2 days. They were very professional (and left no mess behind). Was going to go with a larger company but I am very happy with my decision
Doran
We had a small but challenging residential job: difficult terrain, difficult access, lots of rock, unable to use machinery. Nothing was too difficult for Longain. The team even worked through the rain to finish the job. I am happy to recommend Longain for fencing.

FAQ

1. Why does a chainwire fence need a top rail?

Without a top rail, a chainwire fence depends entirely on post strength and mesh tension to hold its form. In high-traffic or exposed environments, this is often not enough. Over time, the upper section of an unsupported fence can sag, bow under pressure, or lose tension. A top rail runs a solid horizontal rail along the top of the fence, making the whole structure more rigid and far more resistant to deformation.

2. What types of sites is chainwire top rail fencing most suitable for?

Top rail chainwire fencing is well suited to sporting facilities, construction and building sites, industrial and warehousing facilities, schools and childcare centres, commercial developments, car parks, and government or council infrastructure. Any site that experiences regular impact, heavy foot traffic, vehicle movement, or long fence runs will benefit from the added support a top rail provides.

3. Can a top rail be added to an existing chainwire fence, or does it require a new installation?

A top rail can be retrofitted to an existing chainwire fence in many cases. If your current fence is sagging, loosening, or showing wear along the upper section, a top rail retrofit is often a more economical option than a full replacement. Longain Fencing can assess your existing fence and advise whether a retrofit is suitable or whether a new installation would deliver better long-term value.

4. What materials are used in Longain Fencing's top rail systems?

All top rail chainwire systems are manufactured using high-quality galvanised steel. Galvanised steel is chosen for its strength, corrosion resistance, and ability to perform across all Australian weather conditions, including coastal salt air, extreme heat and UV exposure.

 

5. Does top rail chainwire fencing meet government and council compliance requirements?

Longain Fencing’s top rail systems are designed to meet the performance standards required for government and council infrastructure projects. If your project has specific compliance or specification requirements, contact the team to confirm the appropriate configuration for your application.
