Planterworx was founded by Randy Rollner, who studied at Parsons before beginning his career in architectural metal in 1997. "It’s all in the details," says Rollner, and the designers on his team are true artisans and craftsmen who bring the precise, balanced lines normally found in modern architecture to these metal Planters (2011). The Planterworx designers insist on using a high percentage of recycled content and recyclable materials. The Corten® Steel Planters are made of the same material designed for bridges and skyscrapers, which has a reactive patina period of three to nine months, depending on location and climate. This patina or rust acts as a protective barrier and does not compromise the structural integrity of the material.
