Secondary Framing Components

ATAS secondary framing members are used for attachment and structural support for our panel systems in roof, wall and soffit applications. Components include hat, U and sub-girt type members. In addition, secondary framing members may be used in retro-fit roofing applications to create newly applied slope to an existing flat roof. Common applications include the following:

  • Rainscreen systems
  • Equipment screens
  • Mansard type systems
  • Soffit support framing
  • Metal over metal retro fit (roof application only)
