Our Security Grilles offer protection against forced entry for windows and glazed doors. The grilles can made bespoke to your existing windows size and can be fixed or sliding systems. Security Grilles are a cost effective security solution that can be retrofitted to any window or door. Zinc plated pre-galvanised steel is used in the construction of the grilles and are finished with a tough powder coat. The vertical bars are spaced 100mm to 150mm apart to comply with insurance recommendations, horizontal bars are used to reinforce the grille at 500mm apart.
