CG Range

17 of our most popular colours, chosen by Kiwis, baked onto an industry-leading metallic coating.

Our CG Range combines our top-selling material, MagnaFlow prepainted steel, with our 17 most popular colours. It offers exceptional value: the CG Range not only looks great, it's built to last. Below is more about the magic of magnesium, and why MagnaFlow is so well suited to fascia and rainwater systems.

CG Range material: MagnaFlow prepainted steel

The magic of magnesium adds extra anti-corrosive protection

MagnaFlow's superior corrosion resistance makes it an ideal choice for more demanding environments. The magnesium in its aluminium / zinc / magnesium alloy coating helps zinc flow over cut edges, sealing them and providing long-term protection against corrosion.

Below is the MagnaFlow substrate, layer by layer.

MAG-200: 33% thicker, self healing protective coating

MagnaFlow spouting cut away layer by layer: coloured finish coat, primer, pretreatment, aluminium, magnesium and zinc alloy coating, steel core, then pretreatment, primer and Shadow Grey backer

Mag-200 and Mag-150: what the number means

The CG Range is made in MagnaFlow Mag-200.* It has nine corrosion layers and a 33% thicker, self healing protective coating.

The number is the coating weight. Mag-200 carries 200 g/m² of metallic coating (the combined weight of all its layers), and Mag-150 carries 150 g/m².

*In some cases Mag-200 will be substituted for Mag-150. Please review the specific product page for more details.
