The angle standing seam covering is a simplified version of the double standing seam. The angled standing seam roof consists of shares (metal sheets) with lateral upstands, which are interlocked with the adjacent upstand. In contrast to the double standing seam, the last fold is no longer completely folded over, but only into a horizontal position, which creates a wider view of the fold. Due to the lower tightness, this version is only suitable for roofs with a roof pitch of 25° or more (or only from 35° in snowy areas). The wide rebate creates strongly structured, striking roof surfaces.
