NJR Defence in Action: The Steel Security System You Can Trust

29 October 2025

Security today requires more than just a barrier — it demands strength, visibility, and durability you can trust.


That’s why NJR Steel developed the NJR Steel De-fence range — a modular fencing system that delivers high-performance protection without compromising on design.

Discover What Makes Our De-fence So Effective

As you can see in our NJR Steel De-fence video, this isn’t just another fencing solution — it’s a complete system built on strength, visibility, and reliability.


The video highlights how our modular panels, gates, and add-ons come together to create a security solution that looks professional, installs seamlessly, and most importantly, protects what matters most.

The Philosophy Behind NJR Defence


The core principle of NJR Steel De-fence is simple: maximum strength, complete visibility.


Unlike solid walls or closed-off barriers, NJR Steel De-fence panels allow for clear sightlines from every angle.


This not only deters intruders but also ensures that your property remains open, safe, and connected to its surroundings.

A Range for Every Need


The NJR Steel De-fence family offers solutions for every environment — from critical infrastructure to lifestyle estates.


Each system is available in a range of standard heights, with custom sizes available on request.

De-fence Max


Engineered for high-risk areas such as airports, factories, and distribution hubs.


With tightly spaced mesh apertures and an interlocking post system, it’s virtually impossible to climb or tamper with.


Specs & Applications


De-fence Mid


Balance strength and openness, making it ideal for commercial perimeters like garages and retail sites.


Specs & Applications

De-fence Multi


Designed with aesthetics in mind — perfect for estates, schools, and landscaped areas where security must blend seamlessly into the environment.


Specs & Applications

De-fence Econo


Provides a cost-effective option for farms, storage facilities, and sports enclosures without compromising on durability.

De-fence Pool

Specs & Applications


Built to Last


Every NJR Steel De-fence panel is manufactured from high-grade steel and coated for maximum protection.


Electro-galvanising and powder coating ensure a sleek finish and long-lasting resistance against corrosion, while coastal environments can be catered for with hot-dip galvanising and additional protective coatings. This means your fencing continues to perform — and look good — year after year.

More Than Just Fencing


A fence is only as strong as its weakest point, which is why NJR Steel complements the De-fence system with a full range of custom-built gates.


From swing gates to sliding gates and pedestrian access, each one is designed to integrate seamlessly with the fencing panels.


Tamper-proof fixtures, modular posts, and optional add-ons like electric fencing, razor wire, and spikes further enhance protection, ensuring no weak spots in your perimeter.

Smarter Installation


Because NJR Steel De-fence is modular, there’s no need for messy on-site welding or drilling.

Panels interlock neatly, making installation faster, cleaner, and more adaptable.


This also allows for easy future adjustments — whether you’re extending, upgrading, or repurposing panels to protect equipment, generators, or storage areas.

Trusted by Communities and Industry


From lifestyle estates to industrial parks, NJR Steel De-fence has been installed across South Africa, where safety and reliability are non-negotiable.


Customers consistently praise not only the quality of the fencing but also NJR Steel’s reliable delivery and service. It’s this combination of product and support that makes NJR Steel a trusted name in steel security.

Protect What Matters Most


Security isn’t just about keeping danger out — it’s about creating peace of mind, knowing that your home, business, or community is protected by the strength of steel.

Re-roofing a Landmark: NJR Delivers Engineering Precision at NWU Auditorium NJR Potchefstroom was recently commissioned by North-West University (NWU) to solve a persistent leak in the auditorium roof—a complex task due to the very low pitch of the existing structure. Rather than replace the roof entirely, the team opted to erect a new roof structure over the old one. This solution ensured minimal disruption to ongoing activities inside the auditorium. In the absence of an appointed architect, NJR joined the design team directly, offering both product expertise and technical input. Our proposed light steel truss system was reviewed and approved by the project’s structural engineer. The project posed significant engineering challenges. The 40-year-old auditorium had no CAD documentation—only original paper plans. The building’s large, kite-shaped roof spans 70 metres diagonally and 35 metres across the shorter axis, with perimeter wall heights reaching 12 metres.

These included protective enclosures for external air conditioning units, electrical distribution boxes, water tanks, and other vulnerable infrastructure installations—demonstrating the system's suitability for more than just perimeter DeFence.
