ANTHRA-ZINC
ANTHRA-ZINC with its visible grain matches the colour of slate and blends well in combination with photovoltaic panels.
ANTHRA-ZINC is produced through a phosphatation of mill finish Natural zinc. The darkness of the pre-weathered zinc is measured electronically using a Y figure where 0 is black and 100 is white. Acceptable tolerance of ANTHRA-ZINC, y = 5 to 7. ANTHRA-ZINC also includes a thin organic coating.

As with Natural Zinc, based on the type of installation, surface exposure to weather, and geographical conditions, ANTHRA-ZINC may slowly and gradually lighten over time to dark grey. Superficial surface scratches and marks will be covered by the natural grey patina.

While white marks can occasionally appear on zinc surfaces that are unexposed to rain or are not regularly rinsed, such superficial marks do not reduce the material’s lifespan.
