RHEINZINK expands its portfolio of architectural grade zinc options with the introduction of RHEINZINK-GRANUM in a dark gray Basalte and lighter Skygrey matte finishes for roofing, façade cladding and wall products.

Design and building professionals appreciate these popular gray tones for their versatility in both contemporary and traditional architectural styles, and their flexibility in pairing with wood, natural stone, plaster, glass and other building materials. Appealing to building and home owners, the zinc material maintains its self-healing, low-maintenance, corrosion-resistant performance with a potential lifespan of several decades.

"This long-lasting, weather-resistant and sustainable zinc material is ideal for resilient roofing, façade and wall cladding systems," said Charles (Chip) McGowan, president of RHEINZINK America. "RHEINZINK-GRANUM provides owners and designers with an immediate, distinctive dark or light gray finish. Over time, the dynamic qualities of the finish and the zinc alloy naturally patinate to a blue-gray tone."

RHEINZINK-GRANUM's Basalte and Skygrey matte aesthetic is achieved by phosphating the zinc surface using state-of-the-art, environmentally responsible production technology. At the end of its useful life on the roof or wall façade, it remains 100% recyclable.
