The magic of magnesium uniquely adds extra anti-corrosive protection

The superior corrosion resistance of MagnaFlow means it is an ideal choice for more demanding environments, such as roofs 100m from the coastline. The magnesium in the aluminium/zinc/magnesium alloy coating ‘magically’ helps zinc flow over cut edges, sealing them and providing long term protection against corrosion. No other similar-priced metal roofing product offers this superior built-in edge protection.

‘Self healing’ – an exciting innovation

The first signs of corrosion on any steel roof nearly always happen where the roofing product has been penetrated by holes (to secure a satellite dish, for example) or the cut edges necessary in any roof installation.

Our unique alloy technology combines zinc and aluminium with magnesium. The magnesium allows the zinc to literally flow and self heal the cut edges that would otherwise expose the steel substrate to atmospheric conditions, ensuring a much longer life for your roof at a modest additional cost.

Industrial strength

If you are building in an environment where corrosive chemicals may be present, MagnaFlow ‘PLUS’ paint system is a chemically resistant thermosetting water borne acrylic that provides added protection against chemicals in industrial environments such as sites near airports, dairy factories or petrol stations as well as those in areas with geothermal activity.

PLUS paint is only available in a restricted colour range and availability may be subject to longer than our standard lead times. Please consult with your ColorCote distributor or contact us directly.

Colour choice

MagnaFlow is available in all the same great colours as ZinaCore so there’s plenty of choice to match with other features on your house.
