“Very thorough, very efficient, and competitive too..”

Gemsec works with the country’s leading manufacturers of physical security products to offer an unbeatable range of retractable security grilles, steel security doors, anti-vandal screens, etc

Retractable security grilles are a strong physical and visual deterrent suitable for both commercial and domestic use. They’re unobtrusive when not in use and come in three different designs, with the option of colours to fit your environment.

The Optiguard Vandal Protection Window Screen looks like tinted glass but close up provides a strong visual and physical deterrent. Perforations allow the maximum amount of vision and light to penetrate whilst retaining the integrity of the screen. Perfect for buildings where unobtrusive security is paramount.
