Diamond Security Screens Cairns
The traditional welded diamond grille, made as one piece with no screws or rivets to work loose over time.
Diamond grille is the look most people picture when they think of a Queensland security door, and there is a good reason it has stayed popular. The grille, frame and corners are welded into a single piece, so there is nothing mechanical holding it together that can loosen or corrode.
It gives you a solid physical barrier at the door, plenty of airflow, and a finish that suits both older homes and rentals where durability matters more than a modern look.
Available as hinged and sliding doors and window screens, in over 300 powder coat colours.
Part of our Security Doors & Screens range, installed across Cairns and Far North Queensland.
