Weathering Steel - Cor-Ten | BŌK Modern

BŌK Modern designs and fabricates architectural metal systems that blend aesthetic innovation with functional performance, including sunshades, wall screens, guardrails, and canopies. BŌK Modern introduces Cor-Ten weathering steel facade solutions. As the demand for durable, low-maintenance, and sustainable building materials continues to grow, this solution emerges as a leading choice for architects and designers seeking performance, aesthetics, and cost-effectiveness.

Unlike traditional painted metals, Cor-Ten steel develops a protective rust coating as it weathers, enhancing its visual appeal while preventing further corrosion. The material naturally patinas over time, eliminating the need for ongoing maintenance and recoating. Stronger than aluminum, it maximizes material usage while maintaining structural integrity.

Cor-Ten steel has proven ideal for affordable housing projects such as Tahanan, Blue Oak Landing, and Africatown. Its lack of need for additional treatments makes it one of the most economical facade options available while still delivering a striking look. Many aluminum panels require Kynar paint coatings, a process with a significant environmental impact—Cor-Ten steel does not.

Unlike composite metal panel systems, Cor-Ten steel is easily fabricated, curved, and laser-cut to create patterns or shapes unique to site conditions and design intent. BŌK Modern’s mounting methods are integrated directly into the panels, often eliminating the need for additional support structures and reducing both material use and labor costs. The inherent strength of steel enables the integration of structural folds into panels, reducing the need for secondary supports and allowing for long-span applications. Laser-cut openings can be incorporated to allow airflow while maintaining a sleek appearance.

While Cor-Ten steel’s patina evolves naturally with environmental factors such as humidity and rainfall, rust drips can occur in the first months of exposure. Solutions include integral gutters at the base of panels to channel runoff to storm drains or planter areas, as well as gravel or landscaped zones to absorb drips and keep surfaces clean.
