Innovative aluminium material w.15 is here!

The innovative surface finishing of the aluminium material was created for KJG for up to six years. It was attended by the Norwegian supplier Hydro Aluminium and customers will find it under the brand Worahnik with the designation w.15.
Exceptional results in protection against corrosion are achieved by aluminium coils and sheets of metal, which are made of well-formed aluminium alloys. For this reason, aluminium sheets are easily and safely processed. Aluminium sheets are suitable for folded roofs, facade panels, gutter system, roof coverings, or windowsills. Aluminium reacts with oxygen in the air, creating a natural oxide layer. This layer provides excellent anti-corrosion protection.
MAIN ADVANTAGES OF THE MATERIAL W.15
Exceptional
functionality
The new product line is unique in its unpretentiousness and precision. The lightness of the aluminium material enables very easy handling and uncomplicated installation.
Unique
structure
The unique surface structure ensures that the material is not scratched anywhere in the – process - either during production or during final installation. In addition, the high quality of the textured coating provides good colour fastness, and thanks to many years of innovation, the material fits perfectly with the remaining roof accessories and KJG gutter systems.
Self-cleaning
lotus effect
A unique aesthetic benefit of the material is the self-cleaning effect of the surface. Self-cleaning is also called lotus effect – dirt and dust are immediately washed away with rainwater. Thanks to this, the roof looks like new.
Noble
looking
The W.15 also impresses with its matt, and therefore exceptionally elegant surface. The roof drainage optically disappears into the background, looks decent and creates highly tasteful accents that are particularly suitable for contemporary architectural style.
Unquestionable
endurance
The W.15 aluminium material and the W.15 gutter system withstand all kinds of weather conditions such as sunshine, rain, hail, storm and snow. Therefore, KJG provides customers with up to 40 years on material and surface finish for them.
Wide colour
scale
The W.15 material is available in twelve colour shades, which are identical to the gutter system and roof accessories. The availability in the popular STUCCO finish is also new for the W.15.
