Western Rib®
Bare Steel

Architecture, as any compositional art, makes extensive use of symmetry and it’s no mystery why architects prefer using our bare steel Western Rib panels for their projects. The 7.2-inch on center spacing between ribs is aesthetically pleasing and offers symmetrical balance to architectural projects which require a design that compliments the subject of their work – making it an excellent choice for contemporary design applications.

Our 7.2” bare steel exposed fastener panels are ideal for commercial and industrial applications but also work exceptionally well on both parapet walls and facades. With wider coverage and fewer panels to install, the Western Rib trapezoidal design also provides superior load and span capacities, saving money in structural support. Add fiberglass panels to match the profile of the metal panels as decorative accents or to transition smoothly from steel to skylight.

Features

  • 22 Gauge Minimum
  • 1.5” Deep and 7.2” Pitch. The strongest Corten panel that we sell.
  • 36” Coverage means fewer panels to handle and install, saving time and money. There is no loss of material for the panel side lap.
  • Bare Western Rib panel has a unique look and naturally oxidizing finish that make it especially desirable for many architectural projects.
  • Matching trim and flat stock available for bare Western Rib.
  • Galvanized or stainless steel screws in a Koko Brown color are available to match bare steel finish.
  • Fiberglass skylight panels are available to match the profile of this panel.
