ENQUIRE NOW:
In South Africa, a home is more than shelter from the elements. It should be a place of safety. Families need security that works, but few want to live behind heavy bars or lose natural light and views. Many systems fail in coastal environments, under harsh sun, or in the face of local crime. At Alsysco, we take a different approach. We design aluminium security solutions that protect without sacrificing light, airflow, or the way a home feels to live in.
Our purpose is to improve lives by raising the quality of the structures that protect them. Security barriers and screens are central to this. They are not afterthoughts, but part of complete systems designed from the ground up for African conditions. This conviction shapes every Alsysco product.
Most conventional security options ask families to choose between safety and comfort. Thick bars block light and make rooms feel closed in. Imported, flimsy, poorly finished systems often corrode in coastal environments or break down under strong sun. When product selection and installation are rushed, weak points are exposed. If the system fails or needs early replacement, the homeowner pays twice: once in cost and again in lost peace of mind.
We do not accept that compromise. For us, quality is a responsibility. Our security systems are built to last, to fit modern homes, to keep sightlines open where possible, and to perform in the real environments where people live.
The Alushield® range is built to protect doors and windows without compromising design. The Alushield® security gate and fixed window bar are engineered as complete aluminium systems, not just barriers. They provide the strength needed for high-risk settings while keeping lines clean and integrating visually with the home.
These systems are built to resist corrosion in coastal and high-UV areas, fit with modern architecture, and work as part of a modular Alsysco system solution. Because they are systems, rather than stand-alone products, they come with Alsysco’s technical support and quality standards. Accredited Fabricator Partners in our network install them to a consistent level, reducing the risk of shortcuts or poor detailing that can weaken security.
Homeowners can trust that each barrier is designed with the full context in mind: the climate, the security needs, and the long-term life of the home.
CrystalGuard® was created to solve a common problem: security that feels heavy or intrusive. The CrystalGuard® Fixed Window Bar is designed to keep spaces open and light while still providing real protection. It is for windows where people want to keep natural light and views without leaving the home exposed. It is built for local conditions rather than adapted from designs created for milder European climates. The result is a solution that balances security performance with the lived quality of the interior space. Windows remain “the eyes of the home,” not closed-off fortifications.
CrystalGuard® is about solving the real problem. Security is essential, but so is a home that feels open and connected. This product is designed to provide both.
Sliding doors are valued in South African homes for the way they open living spaces to the outdoors and improve airflow. But they can also be vulnerable. The Sanctuary EcoGlide® Sliding Door Security Screen is designed to address this.
Sanctuary works with Alsysco sliding doors featuring 316 or 304 stainless steel wire mesh and a black powder-coated finish. It keeps air and light flowing when the main door is open, so families do not have to choose between fresh air and safety. Built as an aluminium system for local conditions, it withstands corrosion and daily wear.
Alushield® gates and window bars, CrystalGuard® clear window bars, and Sanctuary sliding door screens are part of a bigger picture. We do not just sell products. We work to solve fenestration challenges from specification to installation.
African-engineered performance means our systems are built for real conditions: wind, sun, coastal environments, and security risks. We focus on partnership, not just products. Installers receive training and support so that what is designed is what is delivered. Our principle is simple: build for the life inside, not just for the sale.
This is why quality matters. The cost of a single security failure, water damage after a break-in, or early replacement is far greater than the difference between a basic product and a properly engineered one. Our approach is to make the investment worthwhile through durability, support, and proven results.
Security should not feel like an afterthought added to a well-designed home. When planned early and installed with care, Alushield®, CrystalGuard®, and Sanctuary EcoGlide® can fit the architecture. Clean profiles, matching finishes, and careful detailing make the security feel like part of the design. For fabricators, it provides systems that can be installed predictably and supported after the sale. For homeowners and developers, it delivers protection that respects both safety and the quality of daily life inside the building.
Security decisions are made during construction or renovation. The security choices made during building or renovation shape how families experience their homes for years to come. Alsysco’s barriers and screens are here to raise that standard: stronger protection, better design fit, and systems built for real conditions.

When the structures that shelter people are built right, when the places that shelter people are built without compromise, safety and design support each other. This is the standard we work to uphold.
