The design of Mariposa Hall at Los Angeles Trade Technical College features a series of undulating ribbons jutting out beyond the existing floor structure to identify entranceways, provide canopies and sunshades. Tinco Sheet Metal installed 34,000 square feet of RHEINZINK America Inc.’s 18 gauge/1.2-mm PrePATINA blue-grey Interlocking Reveal Panels fabricated by MetalTech-USA for the building envelope.

Michael Bulander, project designer at architecture firm Harley Ellis Devereaux, says his company reviewed various metals for the ribbons but zinc quickly became the preferred alternative for its organic character and slight variations in the finish as it develops a matte patina over time. “There’s basically no backside to the building,” he says. “So that led to the idea of these ribbons that would encompass the whole building.”

Mariposa Hall was stripped down to its structural grid for the renovation project. New infrastructure systems were installed throughout the facility and it was upgraded to current code compliance. Usable space was increased from 81,807 square feet to approximately 100,000 square feet.
