Colour coated sheets today have a galvalume coating, which is an aluminium-zinc alloy. These sheets combine the strength of steel with the anti-corrosive property of aluminium and the durability of zinc. As a result, these colour coated sheets are an effective energy saving solution as they reflect heat and thus cut back on your cooling costs. You can also be assured that your roof will not catch fire in the event of a lightning strike, nor will the colour crack or peel when subjected to the elements.
Most colour coated sheets are made of Aluminium and it is one the lightest available commercial metals with a density of only a third of steel or copper. When exposed to air, aluminum sheets develop a thin layer of aluminum oxide. This makes them resistant to corrosion and rusting. So you can be sure your colour coated roofs won’t fade when exposed to rain, heavy winds, or bright sunlight. They are non-combustible and have a good fire rating. This makes them safe to use for homes, gardens, warehouses, factories, etc.
