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.
