Why should we use roofing sheets for our roof?
Roofing is a significant component in the construction industry world over. Of late, there has been a shift towards the importance of aesthetics. From wallpaper to contemporary architecture, building construction goes beyond just practicality and functionality. One aspect that is gaining steady popularity is decorative, colour-coated roofing sheets. While we see them mostly in urban and industrialised areas, these sheets can be used not just for large industrial and commercial buildings, but residential buildings primarily for aesthetic reasons and but also as an alternative to the conventional galvanised iron sheets.
Until the mid-19th century, wood, slate and clay tiles were predominantly used as roofing materials. The last century saw asphalt, asbestos and fibre-cement replacing traditional materials. But now thanks to newer, more sophisticated technology, roofing sheets are made from a variety of metals like aluminium, copper, zinc and tin. A long period of market experimentation also saw roofing sheets develop through various levels of durability and fire-resistance. They are also available in different shapes, sizes and gauges to suit every customer’s needs.
The thickness of the colours coated on these sheets varies according to the requirement. Read on to know more about the benefits of using our colour coated sheets.
The most colour coated sheet is made of Aluminium and it is one of the lightest available commercial metals with a density only a third of steel or copper. Since most colour-coated sheets are made of aluminium, they are both lightweight but have a strong and sturdy structure versus other roofing sheet materials.
As most colour coated sheets are made of aluminium, they are non-combustible and have a Class-A fire rating. This makes them safe to use for homes, gardens, warehouses, factories, etc.
When exposed to air, aluminium sheets develop a thin layer of aluminium 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. Colour coated sheets are coated with different colours via a chemical process. This ensures they retain they’re colour and shine for a long time.
A corrugated aluminium roofing sheet is highly durable. They have a high tensile strength at low temperatures, are thermal-friendly and retain their toughness through all kinds of weather. These sheets can also bear heavy loads without getting damaged. Because they last longer than traditional steel roofing sheets, you save money in the long run.
Easy to install
As colour coated sheets are lightweight, they are extremely easy to install. Unlike other sheets, they don’t bend and don’t exert pressure on roofs.
Only three to five per cent of the original energy used to produce the colour coated sheets is needed for recycling. Aluminium also has a very low melting point, so recycling them becomes easy.
Energy reflective and safe
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.
The final and most obvious benefit is that colour coated sheets dramatically increase the aesthetic value of every building as they come in a variety of colours, shapes, sizes and thickness. This makes them suitable for hotels, resorts, airport hangers, restaurants, offices, decorative walling purposes, etc.
