All about the Angle Seam
Description
Traditional Standing Seam (Angle Seam) follows the proven detailing and dimensions utilised in Europe for many years. With secret fixing to the panels and often the flashings, giving very clean lines. Angle seam roofs can show potential undulations (canning) in the wide flat pan which are not only to be expected, but are an architectural feature of fully supported cladding. Zinc and Prefa products are less reflective and can show less canning. Angle Seam typically has a pan width of 250 to 515mm, but custom sizes can be supplied within this range.
