Questions about Diamond Grilles?

Is a Diamond Grille as secure as mesh security screens?

Diamond Grilles provide a strong physical barrier and have a long track record on Australian homes. For the highest certified forced-entry ratings, a tested mesh system such as ScreenGuard may offer additional performance.

No, the open diamond pattern allows light and air through freely, more so than a solid mesh screen.

Yes, many Diamond Grille doors and screens can be fitted with an insect mesh infill behind the grille for added protection against flies and mosquitoes.

Frames are available in a range of powder-coat colours to match your existing doors and windows. We confirm current options during your quote.

Yes, the pattern’s classic look is a common match for character and heritage-style properties, alongside standard modern homes.
