Window & Door Security Grilles

Often referred to as Flag shaped, or T-shaped Windows / Doors security grilles, are all made to measure in every case for the perfect fit. As for installing them,, we offer two options: Self installation, with simple, and easy instructions, or premium fitting service, completed by our colleagues.

It has been widely advocated by crime prevention officers, that the only way to prevent a burglary is to physically strengthen potential entry points, such as windows and doors. Our security window / door grilles are specifically designed with appearance and safety in mind, without compromising on strength. They not only act as a deterrent, but also as a physical barrier. All our domestic window / door security grilles are fixed in all four corners to form a continuous frame – for added protection against forced entry. Due to the unobtrusive design, our expandable security grilles take up very small space when not in use, and can be hidden behind the curtains easily. They are also very simple to operate and slide smoothly with one finger. These sliding window / door security grilles can be unlocked in an instant in case of emergency situations. They even allow sleeping with the window open during summer nights, when locked in safely without having to fear any intrusion.

The top coat of all security grilles are finished with a white polyester coating over rust proof primer for maximum durability and deterrent visibility. No maintenance required.

Advantages of Our Grille Systems

• Multi-Purpose: Designed for both homes and businesses, they fit a wide range of window and door styles.
• Stylish and Functional: High-security doesn’t have to look industrial — our grilles complement your property’s appearance.

Grilles vs. Shutters and Bars

• External Shutters – While they offer a strong visual deterrent, roller shutters are often associated with crime-prone areas and may be restricted by local planning rules. They’re also prone to vandalism like graffiti — making internal grilles a more desirable alternative.
• Internal Security Grilles – More discreet and aesthetically pleasing, internal grilles offer high security without compromising interior design. They are quick to open in an emergency and ideal for properties that value both form and function.
• Traditional Bars- Though effective as a barrier, fixed bars can obstruct escape routes and detract from your property’s look. They often lack the ease of access that modern retractable systems provide.

How Our Grilles Work

• Simple Mechanism: Slide open or closed effortlessly — no heavy lifting, no fuss.
• Tamper-Resistant Locks: Our integrated locking systems are engineered to resist picking, snapping, or forced entry.
• Quick Release for Emergencies: Designed for safety as well as security, our grilles can be swiftly unlocked when needed.
