For more than 40 years, Plannja has refined steel for roofs in Sweden and abroad. We have developed resistent roofing solutions and roof parts, which withstand everything from sliding ice sheets to extreme differences in temperature.

Hand in hand with the technical development, Plannja’s design development is continuously ongoing. What other material than sheet metal can offer 19 colours and half a dozen different profiles?

Steel or Aluminium

Plannja’s roofs consist of a core of hot galvanised steel or of aluminium. In addition, several protective layers and coatings make Plannja largely a maintenance-free alternative. The low weight of the Plannja roof is gentle on the person laying the roof and for the roof construction itself. A concrete tile roof weighs ten times more than Plannja’s tin roof and 20 times more than our aluminium roof.


Aluzink is steel sheet protected by both aluminum and zinc, an effective way of protecting the material. Often, you use the sheet in natural design without coating because it has a unique expression.
