The tiles are designed to Fibrocanal dressing corrugated roofing sheets.
The contour is smaller than that of the ordinary tile. They are especially suited to small waves (17.7 cm) fiber cement plates.
The curve of the fiber channel tile perfectly matches the wave of the fiber cement sheet to provide a traditional finish (you can see this in the slideshow photos).
This fiber channel is installed ONLY on the top of the wave and not in the runoff channel. (See diagram.)
