Which CSI division number corresponds to information about structural steel?

• A. Division 01
• B. Division 05
• C. Division 10
• D. Division 15

Answer: (B)

The key idea is how CSI MasterFormat organizes information by material category. Structural steel is a metal component of the building’s skeleton, so its details—like specifications, fabrication, and connections—are placed in the Metals division. Division 05 Metals covers structural steel, metal fabrications, and other metal items. The other divisions focus on different areas: General Requirements ( Division 01 ) handles project management and administrative aspects; interior specialties and finishes ( Division 10 ) cover non-structural interior items; and Division 15 ( Mechanical ) deals with mechanical systems like HVAC and plumbing. So for structural steel, Division 05 Metals is the correct home.
