Commercial/ Institutional are sectors of what sheet metal specialty?

• A. Architectural
• B. Residential
• C. Industrial
• D. Structural

Answer: (C)

Commercial/Institutional are sectors of architectural sheet metal. Architectural sheet metal covers metal building components—facades, trim, gutters, coping, decorative metalwork—used across different market types. When you categorize by market, you’ll see residential, commercial/institutional, and industrial as sectors served by this specialty. So those sectors belong to architectural sheet metal, rather than the structural specialty (which deals with the metal framing itself).
