Standing Seam

Standing seam roofs are similar to trough sections in that they have a wide pan and a vertical rib, and they are secret-fixed. They are usually wider, having a single tray of 300 mm to 500 mm wide, which gives a unique appearance.

Standing seam roofs are based on traditional manufacturing methods using folding and hand tools, rather than roll forming (see 15.4), but now they are also available roll-formed in most iterations. They are traditionally installed on sarking, but high tensile versions (that do not require continuous support) are available.
