Engineered perforated corten panels combine a pre-aged weathered steel finish with a ventilated rainscreen façade system, offering a low-maintenance exterior cladding solution.
The perforation profiles can be aerodynamically optimized to enhance air circulation, reduce glare, and improve privacy-while still allowing natural daylight to pass through.
Pre-configured panel modules with hidden mounting hardware and anti-runoff detailing ensure fast installation and help prevent staining of adjacent surfaces.
Design & Visual Performance
Controlled Patina Development
Each corten panel is pre-weathered to a controlled color range, ensuring surface tone consistency and enabling faster patina stabilization on-site. This reduces initial weathering runoff and minimizes early maintenance.
Performance-Driven Perforation Options
Perforation ratios (typically 18%–35% open area) are selected based on airflow needs, daylight penetration, acoustic control, and wind load. Multi-layered or gradient perforation patterns create dynamic light effects without producing visual hotspots.
Structural Durability & Buildability
Modular panel assemblies with slotted mounting brackets accommodate thermal expansion. Factory-applied return folds and stiffeners help maintain flatness and reduce oil-canning. Optional drip-edge trays limit water streaking on walls below.

Corten Steel Design Guidelines
Welding
Use weathering-steel compatible welding wire to ensure weld seams age at the same rate as surrounding metal, forming an even patina.
Moisture Management
To avoid moisture accumulation:
Maintain drainage slopes
Prevent recesses where water might collect
Incorporate weep holes or open joint details
Coastal / High-Salt Environments
In marine climates, the patina may stabilize slower. Recommended:
Clear sealing coatings
Protective backing layers
Using stainless steel (e.g., 316) at critical joints
Runoff / Staining Control
Reduce staining by:
Using drip edges and runoff channels
Pre-weathering panels before installation
Protecting nearby absorbent materials (stone, plaster, concrete)
