Angled Seam

The angled seam is the same as a standing seam but has only been folded over by  90°, not 180°. It is considered only suitable for walls and pitched roofs, but not for low slope roof cladding in exposed areas.

The angled seam has the advantage of a more dominant and a straighter line, which is obtained by a roll forming machine rather than hand working, and it is used when the aesthetic expectations are high. The angled seam is restricted in snow areas to a roof pitch of more than 25°.
