N Roof Deck

N Deck Overview

Type N (Deep Wide Rib) is a 3″ deep roof deck well suited for applications where it is desirable to space the supporting members as far apart as possible. This is often the case in structures such as gymnasiums where it is usually more economical to minimize the number of long span structural members.

  • Standard N Deck
