Material
11 Metric Tons
22 Gauge RHEINZINK® prePATINA Blue-Grey Titanium Zinc
The project utilized factory pre-weathered architectural zinc selected for:
- exceptional corrosion resistance
- natural weathering characteristics
- maintenance-free finish
- long service life
- sustainable, recyclable material
The naturally developing patina allows the building to age gracefully while requiring minimal maintenance over decades.

Architectural Metal Systems
The building combines two traditional architectural zinc systems:
Flat Lock Tiles
Used to articulate the feature walls surrounding the entrance while allowing installation over curved and irregular surfaces.
Double Lock Standing Seam Panels
Installed where larger continuous panel surfaces required exceptional weather resistance and long-term durability.
Together, these systems create a refined exterior that emphasizes light, shadow, and texture while maintaining the clean architectural language envisioned by the design team.
CSI Contribution
Working closely with Van Mulder Sheet Metal, CSI developed fabrication details that transformed the architect’s design into buildable, high-performance zinc assemblies.
Every panel, flashing, and transition was custom fabricated to maintain:
consistent joint spacing
precise alignment
concealed waterproofing
clean architectural lines
seamless integration with curtain wall and glass block systems
The result is a façade that continues to perform decades after installation while retaining the timeless appearance characteristic of natural zinc.
