  • Features & Benefits

    Features & Benefits | Western Rib Metal Roofing/Siding Panels

    • Economical – There is no loss of material for the lap. Western Rib will yield 36" coverage and that means fewer panels to handle and install, saving time and money.
    • Corrosion & Rust Resistance – Our metal roofing and siding panels and sheet steel products are coated with an aluminum-zinc alloy coating (AKA Galvalume®/Zincalume®). This creates extraordinary outdoor corrosion resistance.
    • Durable - Metal Roofing coated with an aluminum-zinc alloy coating (AKA Galvalume®/Zincalume®) will have an exceptionally long life expectancy.
    • Pest and Termite Resistant - Bugs, pests, and termites cannot penetrate through metal materials making a corrugated metal roofing system your best defense against unwanted creatures.
    • Fire Resistant - Metal roofs are noncombustible and have a Class A fire rating. Class C rating when applied over a combustible material such as wood shingles.
    • Wind Resistant - Metal roofing can withstand powerful wind gusts.
    • Lightweight - Lightens the load in installation and reduces the load bearing weight on support walls and beams.
    • Stylish - Available in various colors and can be ordered in a variety of premium specialty finishes.
    • Energy Efficient - Metal roofs with a "Cool" paint finish reflect solar radiant heat, which can help reduce cooling costs.
    • Eco-Friendly - Metal roofing is made from recycled content. Western Rib panels are also recyclable at the end of their life as a roof. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream - up to 20 billion pounds per year.

Western Rib - Zinc Patina®

7.2 Panel

Zinc Patina is a pre-painted metal that is designed to look like an old and weathered zinc roof. The dull gray colors mixed with the patterns of patina create a visually stunning roofing panel. It is a good alternative to real zinc at a fraction of the price and has a paint warranty. Zinc Patina looks excellent from BOTH up close and from a distance.

The three main advantages in using Zinc Patina® when compared to real zinc are:

  1. Cost savings of 35 % to 50 % when compared to real zinc.
  2. Zinc Patina arrives looking patina'd. You don NOT have to wait for it to patina.
  3. Standard Paint Warranty With Zinc Patina. Real zinc does NOT have a WARRANTY.

Zinc Patina can be used in exterior or interior applications. It is a perfect solution for an interior application as it arrives looking patina'd.

If you are interested in this color I would highly recommend requesting a sample of Western Rib in Zinc Patina. You really need to see this panel up close to appreciate the beauty and authenticity of this paint finish.


Architecture, as any compositional art, makes extensive use of symmetry and it’s no mystery why architects prefer using our Western Rib Exposed Fastening Roof 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” 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.

Metal Roof Design Ideas

Western Rib® is easy to install and can be used in a variety of applications including roofing and siding material for commercial, industrial, agricultural, and residential projects.

  • Exterior applications: Total roofing area, an accent to a roof in conjunction with other architectural elements of design, metal siding, decorative fencing, restaurants, movie sets and much more.
  • Interior applications: Focal point or backdrops such as backsplash in a bath or kitchen, textured ceiling, and a wall treatment.
