Weathering Steel Guide Part 2: How Preweathering Steel Works
Explore how preweathering accelerates and refines the patina process on weathering steel, giving designers control over surface aesthetics, timeline, and performance. Through controlled oxidation cycles and preparation techniques, preweathering produces rich, stable surfaces that emulate years of natural exposure while minimizing loose rust and runoff. Understanding the science and methods behind this approach helps teams balance design intent with practical considerations in architectural applications.
Weathering Steel Guide Part 1: The History of COR-TEN Steel
Explore how weathering steel — often called COR-TEN or Corten — evolved from a utilitarian industrial alloy into a material with powerful architectural appeal. Originally developed in the 1930s for heavy-duty applications, its ability to form a stable, protective rust patina caught the attention of designers in the mid-20th century. Early architectural uses showcase how its rugged, earthy tones and enduring performance reshaped modern design approaches.
Labs Report 002: Notes from the Field
Zahner Labs employs a spiral development method for producing products, tools and services. We take ideas through a series of Design > Build > Test > Analyze loops, which allow for stress-testing concepts and integrating feedback. We’ve employed this process in previous product concept “splashes,” including Zinc Concepts, SurveyLink, and Precision Patina.
Reducing Manufacturing Wastewater Production With Ion Exchange
Sustainability is more than just an industry buzzword at Zahner. It’s a daily commitment to preserving and protecting the natural resources we’ve been entrusted with and using them responsibly in the built environment.
City View Garage in Miami’s Design District Features 3 Iconic Facades by Zahner
Completed in 2015, the City View Garage in Miami’s Design District stands as a captivating feature in a neighborhood surrounded by iconic works of architecture. The development was led by Dacra, who, over the years, has transformed the district from an overlooked and stagnant area into a thriving center for commerce and culture.
