Security grilles are typically metal structures or barriers, that are installed over doors, windows and other openings, to provide added security against break-ins or unauthorized access. They are commonly used in commercial buildings, shopfronts, and residential properties, to deter intruders and protect against burglaries. Security grilles come in various designs and materials, such as steel, aluminum, or wrought iron and can be customized to fit different door and window sizes. They can also be customised to fit different shape openings. Security grilles are often equipped with locks or other security features to prevent tampering or forced entry.

Types of Security Grilles

Roller Grilles: These are a type of security barrier often used in commercial settings, such as retail stores, shopping malls, airports, and warehouses. They consist of a series of interlocking slats or links that roll up and down, to either secure or allow access to an area. They are typically made of aluminum or steel. 

Accordion Grilles: Also known as collapsible gates or retractable grilles; they are flexible, retractable barriers used for security and space management in various settings. They are commonly made of durable materials like steel, aluminum, or plastic and are designed to fold up in an accordion-like manner when opened, providing a clear passage when not in use. They are often used for larger openings and provide a good balance of security and accessibility.

Fixed Grilles: The grilles are permanently affixed to a wall or frame. They are commonly used for windows or as a barrier in specific areas. They can take the form of window bars, which are horizontal or vertical bars that are installed on the outside or inside of windows and fixed permanently.
