The Advantages of Roofing Sheets

Thin sheet metal is more than just a tough material with a long life expectancy. It is also one of the few materials that can be recycled any number of times without losing its positive qualities. Thus thin sheet metal is a major asset in sustainable community building.


From Tiles to Steel Sheet

In addition to being a very durable material, thin metal sheet’s light weight is a major advantage. Steel sheet exerts less of a load on a roof structure than clay or concrete tiles. This usually means you can switch to a metal roof without any problem. But remember, preparatory work must always be done properly no matter what type of roofing you choose.

Profiles and Colours for Everyone

Thin sheet metal is a flexible material that is easy to shape. This becomes apparent from our wide range of stylish roofing profiles to choose from. They are all available in a variety of inspiring colours taken from nature’s own palette. It’s easy to find a roof that suits you, your home and your surroundings.


A Natural Choice

At Plannja, we use galvanized steel sheet in the majority of our products to help them stand up to harsh environments. And there’s a paint coating to provide extra protection. Plannja is a GreenCoat-partner, and the eco-friendly GreenCoat BT-coatings are chromate-free and based on natural oils from the plant kingdom.



Thin sheet metal is a fantastic roof and exterior wall material. It has been used for hundreds of years to protect everything from churches to barns from the elements. In many of our cities, we can still see buildings with metal roofs dating back to the late 19th century. Their survival until today is not by chance. You’ll have to search far and wide for a building material with a longer life expectancy.


Ideal Material

For many, the big advantage with our sheet products is that they are practically maintenance free. Only minimal effort is necessary for the roof to protect your home year after year. Because metal sheet is inorganic it does not bind moisture, which is great when you want to reduce the risk of things like moisture damage and fungus – yet another advantage. In other words, metal sheet is an ideal material for roofing and rainwater systems that you can rely on over time.


Aluminium for Harsh Environments

Rain and damp in coastal environments, big cities and close to industries, may contain salt or acid pollutants with low pH values. In such surroundings roofs and walls are exposed to great stress in the form of corrosion.
