Panel Profile
What this panel actually looks like in cross-section — including how it's fastened.
One profile across three options — the Glossy, Textured, and White Liner panels are all the same Tuff Rib Ag rolled shape. They differ only in gauge and finish: 28-ga glossy, 26-ga textured, or 29-ga white liner. Screws seat in the flat valleys between the 3/4" ribs.

White Liner Panel
Get pricing →The White Liner Panel is the same Tuff Rib Ag profile in a thinner 29-gauge metal, available only in white, with a lesser exterior-grade paint and no warranty. It's designed for bright white interiors — ceilings and walls in warehouses, shops, and barns — priced for secondary applications.

Warranty Coverage

- ✓40-Year Weather XL Paint Warranty — Both the glossy and textured finishes use the Sherwin-Williams Weather XL paint system.
Frequently Asked Questions
What gauge is Tuff Rib Ag?
Tuff Rib Ag is available in two options: 28-gauge Grade 80 Galvalume with a glossy paint finish, or 26-gauge Grade 80 Galvalume with a textured paint finish. Both use the same Tuff Rib profile — the gauge and finish are the only difference.
How wide does a Tuff Rib Ag panel cover?
Each Tuff Rib Ag panel covers 36 inches (3 feet) of width. That means 1 linear foot of panel equals 3 square feet of coverage.
What purlin spacing does Tuff Rib Ag require?
For roofs, purlins must be no more than 24 inches on center (16" OC is also fine, as is direct application over plywood sheathing). For vertical sidewalls, purlins can be up to 36 inches on center.
Where does the screw go in a Tuff Rib Ag panel?
Screws seat in the flat plane right beside the rib — never through the rib itself. Fastening through the rib crushes the round top and creates a poor seal. The flat valley between ribs is approximately 7 inches wide with modern EPDM-washered screws rated for 40+ years.
Can Tuff Rib Ag be used on a residential roof?
Yes. Tuff Rib Ag is widely used on residential homes, garages, barns, sheds, and agricultural buildings across New England. It's the most common exposed-fastener profile in the region.
What warranty comes with Tuff Rib Ag?
Every Tuff Rib Ag panel carries two manufacturer warranties: a 40-year WeatherXL paint warranty (covering both the glossy and textured finishes) and a 25-year Red Dot Galvalume metal warranty.
