WHAT OUR CLIENT’S ARE SAYING
“We’ve had such a lovely experience with Defendoor from the very beginning. We were looking to install security gates in our lounge and kitchen and after meeting a few providers, we made the decision to go with Defendoor, because of their honesty, transparency and quality.
Their service was really good, especially from Hugo and his team who fitted the gates.
2 years later, I needed assistance to replace a lock (because I used the wrong key and it got stuck, not a gate issue). I just called Hugo who assisted, and the guys come out the very same day.
Feel like we made the right choice with this provider!”
“We were impressed by the professional way in which the products were installed. The installers were friendly, efficient and left our house clean after the installation. The product itself, namely two retractable security gates, is strong and clearly made from high quality material. Since our gates were installed, we have felt safer.“
“The installers were professional, friendly and had positive attitudes. They cleaned up after the installation and worked fast and efficiently. The door is a beautiful color, it is very strong and solid. I highly recommend this company.”
“I had a very positive experience interacting with Defendoor right from the point of quotation and measurements (Hugo) to installation (Freddy and Shaka). Hugo was in and out of my house within minutes. I did not feel hassled or harassed in any way. The same was with Freddy and Shaka – very professional guys. They introduced themselves like true gentleman. They carried all their own equipment and cleaning material and carried out the installation with efficiency and expertise. Thank you Defendoor. I appreciate your good service.“
“The most satisfyingly service I have ever had. Excellent service, professional and clean installation. I recommend DEFENDoor to anybody that require security doors and/or windows. Thank you to Hugo for his good service.“
“Defendoor has outstanding service. The product was delivered sooner than expected. Hugo really took care of the customer requirement. Shaka and his team were super and fitted the doors in with precision.“
“Best home sliding security door I have ever had.. going 9 years now with no problems. Best quality and home security door!“
“After a recent break-in I contacted several security gate companies for quotes. The agent that came to take measurements made a recommendation that I took and am very pleased with. It looks great, matches the current color scheme of the glass door metal and is made of galvanized stainless steel. The keys and lock mechanism is unique to Defendoor and tamper proof. I’m really impressed.
The guys that came to install the gate was quick and did a good job. Nothing broken and that needed repairs afterwards. Work was neat and proper. They even stopped working when I had to take calls; very professional. Would definitely recommend!“

Proudly Manufactured in Johannesburg
Every DEFENDoor is designed and built at our Johannesburg facility using locally sourced steel and materials. Supporting us means supporting South African industry, and receiving personal service from a company that knows your world.
Tamper-Proof, Durable Construction
Our doors are engineered to withstand high-impact force, prying tools, and corrosion from the elements. No matter if you’re in a high-crime area or coastal region, you can trust in long-term protection backed by meticulous manufacturing standards.
Custom Solutions for Every Space
No two buildings are the same – and your security needs shouldn’t be either. We design doors to fit your specific entrance, frame, or opening. From suburban homes to retail stores and office blocks, our range is made to match.
Style That Doesn’t Compromise on Safety
Choose from a variety of powder-coated finishes to complement your existing design. Whether you prefer a sleek modern look or a traditional cottage-pane style, your security solution will look as good as it performs.
Nationwide Delivery and Expert Installation
Based in Johannesburg, we install across Gauteng and deliver across South Africa. Our professional installers make sure your door is fitted correctly the first time – secure, clean, and ready to last. With DEFENDoor, you’re not just buying a product. You’re investing in peace of mind.
Built to Withstand South African Conditions
South Africa’s climate is as varied as its landscape, from the highveld’s dry winters to the humid coastlines and the searing summer heat of the interior. Combined with a high demand for reliable home and business protection, these factors make durability non-negotiable.
At DEFENDoor, our security doors are designed with local realities in mind. Each unit is constructed from high-grade steel that stands up to the elements and resists the wear and tear of daily use. No matter if you’re in a dry, dusty region or facing salt-laden coastal air, our weatherproof powder coatings help prevent rust, corrosion, and premature ageing. Our UV-resistant powder coatings help prevent fading.
Security is also about resilience. That’s why our doors feature tamper-resistant designs, secure frames, and reinforced locks that are built to deter crowbars, grinders, and forced entry attempts.
From Johannesburg suburbs to small-town storefronts and holiday homes in the Western Cape, DEFENDoor doors offer peace of mind where it’s needed most.
Your environment shouldn’t weaken your protection. With DEFENDoor, your security is built to last – wherever you are in South Africa.
Professional Installation – Done Right the First Time
At DEFENDoor, we don’t just manufacture security doors, we make sure they’re installed to perfection. Our in-house team of experienced installers is responsible for every fitting for consistency, accountability, and peace of mind. We never outsource our installation work, which means no subcontractors, no guesswork, and no shortcuts.
Each security door is custom-built to your exact specifications, and we ensure the installation matches that precision. Whether it’s a single door in a private home or multiple units in a residential complex, our team works efficiently and respectfully with minimal disruption and maximum care.
We believe that a security door is only as strong as its installation. That’s why we take pride in fitting each unit securely into its frame, testing its integrity, and ensuring that it looks as good as it performs. From welded frames to expertly applied finishes, our installations are clean, reliable, and built to last.
With DEFENDoor, your safety isn’t just in the steel — it’s in the service.
