Zinc Composite Material – Rainscreen Cladding

Combines natural beauty of zinc with the flatness, durability, of ACM.


ZCM is available in natural blue-grey, pre-weathered finish that matures over time as it is exposed to air and the elements.

Composites are less likely than metals (such as aluminium) to break up completely under stress.

Perfect for buildings that must project a natural, powerful image and can be used in natural settings, historic districts, or as accents to older buildings undergoing renovation.

Scratches and imperfections melt away over time as the natural patina develops and matures.

The material is non-corrosive, environmentally friendly natural product with 100% clear water runoff.

Provides design flexibility, as the material can be moulded into complex shapes
