AL line

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.

Earth
The Earth line features a range of colours inspired by the colours of nature. Designed for welcoming atmospheres to be completed with colours that give the character that only nature can deliver to what it touches and expresses.

Anodic
Technical, precise and design-oriented. The anodic line contains innovative colours, furnishing environments designed to convey technological and avant-garde concepts.

Inspiration
Inspiration is the color line that reinterprets the representative trends of the most important architectural buildings. A range of colors inspired by the most influential aesthetic lines and the taste of the best designers, which can be used for any type of construction.
