Standing Seam II/Standing Seam 360

In American standing seam roof systems, the roof floats on a system of sliding clips that prevent damage from thermal expansion and contraction. Standing seam designs also eliminate 80% of the through fasteners found in other systems for greater weathertightness. American Standing Seam ll and Standing Seam 360 panels provide 24" width coverage with 3" high ribs. Standing Seam 360 panels are joined by an electric seaming machine, developing a full 360-degree rolled seam to ensure weathertightness - a seam type preferred by many architects and specifiers.
