AL line

The AL line range represents the most classic colours.
The traditional glossy finishes are flanked by opaque colours, with a covering effect and excellent scratch resistance

Raffaello line

The Raffaello line was developed in collaboration with important architecture firms and offers two different finishes: smooth and hammered. Both, thanks to a particular “pointillism” technique obtained by controlled mixing of several colours, give an exclusive effect to sight and touch.

Sablè line

The Sablé finishes have a multi-sensory effect for those who experience them… fantastic to look at and rough or satin to the touch. The sandblasted effect is very versatile, contemporary and easily combined with renovations and living spaces with an innovative flair.

Decor line

Decor combines the strength of aluminum with the aesthetic component of wood. The line faithfully reproduces the grain of traditional wood, thanks to the sublimation process carried out on the painted substrate.
