We have more than 25 years of experience in manufacturing and installing retractable security grilles for patio and french doors. These doors tend to be wide, and inviting for burglars, and therefore it is very important to secure them with a visual deterrent as well as a physical barrier. They also tend to open from a highly frequented area, typically a lounge for example, it is therefore also a great advantage if the security grilles still look discreet and elegant, not to disrupt the overall feel and look of such a main living area. Our sliding security grilles are designed for all these in mind: ultimate security with a neat design. Below are some of the patio / french doors with our collapsible security grilles.
