Reasons to choose aluminium
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. Plannja’s series of profiled aluminium roofing and wall cladding has exceptional tolerance to salt and acidic oxides and is therefore an excellent choice for roofs and walls in aggressive environments. If aluminium sheet suffers a scratch or other damage, an oxide layer is immediately formed on the exposed surface. This means that the aluminium actually repairs itself and always protects against corrosive attack – whether or not the sheet has a protective paint finish.
Aluminium’s main advantages include low weight and the ease with which it can be processed.
Advantages of roofing sheet
Aluminium and steel have several shared advantages compared to many other roofing materials.
• Low weight. A concrete tile roof weighs more than ten times as much as a Plannja steel roof and 20 times more than our aluminium roofs.
• 100% Recyclable
• Non-organic; does not bind moisture
• Requires minimal maintenance
• Long-lasting
• Easy to work
