Armoured gratings
Lumen 3 and Lumen 4
The strength of steel certified to burglar resistance classes 3 and 4
Bauxt’s armoured Lumen gratings are the right solution to secure windows, French windows and service access doors of homes, offices, commercial premises and shops. They feature a strong steel construction, enhanced by a number. Lumen gratings are much more than a deterrent. They are an active protection solution against intrusion attempts and, following the same classi cation of armoured doors (Standard UNI EN 1627:2011), are available in Class 3 (resistant to crowbars, saws, etc.) and in Class 4 (resistance to drills, axe, hack saw).
Our Lumen gratings are available in a variety of configurations and sizes, from a basic fixed version to single or double leaf opening versions for windows, French windows and patio doors. Their reduced overall depth (only 30 mm) makes them ideal to be used with thinner walls. They are suitable for outdoor installations, even in the more severe climates. Based on the specific configuration selected, friezes, decorations and inserts (even customer-designed if required) may be added to the bars within a specific 100 mm area designed for this purpose.
