When smart design meets technical refinement. The irregular canting creates vibrant light and shade effects depending on the position of the sun.

However, the canting has an even more important role: It reinforces the panels, ensuring greater resistance. An additional characteristic is the tapered standing seam which has a number of uses:

  • Absorbs lateral expansion


  • Available in 10 standard colours
  • 2 formats (short and long) to create an offset appearance
  • Installation without clips
  • Complete range of accessories
  • 40-year guarantee
