They are the most economical choice for most applications. We offer them in 26 and 29 gauge in no fewer than 10 standard colors.
Standing Seam Roof (SSR) Panels – are a mechanically seamed trapezoidal standing seam roof system that are suited for simple sloped roofs without hips, valleys, dormers, etc. These panels can be installed over solid deck or substructural members and minimum slope of ¼:12.

They are available in 24 and 26 gauge in a wide variety of colors as well and they are 24” wide instead of 36” like R-panels.
