Tuff Rib Metal Panel
The Tuff Rib panel from Evolution Metals is a classic exposed fastener solution that balances price and performance. This 36" wide panel features a 3/4" rib profile and subtle corrugation, making it a versatile choice for residential roofs, interior walls, and agricultural siding.
With a 5° overbend and integrated anti-siphon groove, Tuff Rib delivers reliable weather resistance even under heavy rain and snow. Pair it with Dripstop lining to control condensation and protect insulation layers in barns, garages, or metal buildings.
