Plannja coatings are very important. Not only because they give you a wide range of colors to choose from, but also because the coatings provide a long and lasting protection for the metal sheet. We have four different coating systems.

Hard Coat

A roof must resist snow, ice and pouring rain. As well as the chimney sweep’s boots and the blazing sun. Our surface coating, Hard Coat, has been developed with this in mind and it therefore becomes a quality concept within the building industry. Hard Coat is polyester-based with unique additives, which give it a very hard and scratch-resistant surface. In spite of the hardness, Hard Coat is flexible and withstands any movements in the roofing sheet.

Our rainwater system in aluminium is coated with Hard Coat Glossy. 


GreenCoat Pro BT

GreenCoat BT (biobased technology) is a new generation of painted steel sheet. The concept is patented for organic surface coating. A significant part of the conventional solvents has been replaced by renewable solvents produced from natural oils. From an environmental point of view, GreenCoat BT is beneficial and leads to less carbon dioxide load on our atmosphere. In addition, the coating is the only non-chromatic product developed for Nordic conditions. GreenCoat Pro BT is available in both a matt and a glossy finish.


GreenCoat Mica BT

GreenCoat Mica BT is a GreenCoat BT coating with an exclusive and glossy textured surface. It has been developed especially for use on roof profiles with high aesthetic requirements.



Polyester 25

Polyester 25 is a standardized and economical color system with good properties for gloss and colour retention. The coating consists of two layers with a total thickness of 25 m and is adapted for roof and facade profiles.
