Aluminium Security Doors & Window Screens
Our aluminium security doors are built to do more than just look good; they’re designed to give you real peace of mind.
Using a high-strength perforated aluminium sheet, powder coated right here in Australia to strict standards, each screen is engineered for durability without sacrificing visibility. The riveted aluminium retention system locks everything firmly in place, creating a screen that’s tough, corrosion-resistant, and still offers clear, unobstructed views.
Security isn’t an afterthought either. With a built-in 3-point locking system, Alu-Gard adds an extra layer of protection where it matters most, your doors. It’s a simple upgrade that makes a noticeable difference to how secure your home feels day to day.
Strength & Durability from Perforated Aluminium
Alu-Gard utilises a strong (1.6mm thick) aluminium sheet that is perforated and powder coated in Australia to standards.The sheet is retained in a frame with riveted aluminium infill retention system.The resulting screen is strong, extremely resistant to corrosion and provides excellent direct clarity of vision.
Colour Range
And when it comes to style, you’re not boxed in. Alu-Gard comes in a wide range of powder-coated colours and anodised finishes, making it easy to match your existing doors and window frames without compromise. The end result? A screen that delivers on strength, security, and street appeal, all in one clean, low-maintenance package.
