Dimond Roofing – MagnaFlow™



TOP 3 Benefits:
• Health and Eco-Toxicity
• Product Stewardship
• Fit for purpose

MagnaFlow™, a roofing product is made up of a hot dipped aluminium/zinc alloy mixed with magnesium  coating over a steel substrate. This enables the zinc to seal the cut edges thus preventing premature corrosion. The substrate is coated to at least 240gms/m2 coating weight and manufactured to AS 1397:2011 standard. The product can be used in atmospheric conditions classified as C1-C4 and is designed for the more demanding atmospheric conditions.  The product is pre-treated with a corrosion resistant chromate conversion coating and primed with a flexible corrosion resistant chromated primer with nominal film thickness of 7μ on the top side and 5μ on the reverse. The finish is completed with a flexible exterior acrylic, polyester or modified coating with a nominal thickness of 18μ.

MagnaFlow™ can be supplied with an optional protective film. The product is tested to ASTM D5178-13 scratch resistance test and experiences no loss of paint adhesion after it is struck on the reversed side in line with test requirements specified in AS/NZS2728:2013 Table 2.2 and appendix E. This product also meets the requirements of AS/NZS2728:2013 Sections 2.8 and 2.10 Salt Spray, Sections 2.8 and 2.9 Humidity resistance and Sections 2.8 and Table 2.4 QUV resistance (durability of coating system) after 4000hrs exposure.
