Double Standing Seam

• Fine seam lines give a slim appearance
• Harmonises with both traditional and modern architecture
• Feasible with conical surfaces as well as concave and convex rounded surfaces
• Feasible at a roof pitch from as low as 3°
• Simple, efficient installation
• Rain proof long-seam connection
• Use of pre-shaped courses
• Courses can be in lengths of up to 16.0 m

Double Standing Seam

With respect to the material zinc, the dual standing seam counts as a development of the original wooden seam / simple standing seam. Since literature of 1899,  it has been the clear preference over other systems, for rooves with a slope of under 25° (minimum slope 3° or 5%). The name "dual standing seam" is characteristic of one of the of the classic long connection types  - courses installed alongside one another, outside of the water level. At a minimum seam height of 23 mm, the dual standing seam is rain proof without any additional treatment. The 25 mm high, dual standing seam produced with with pre-shaped courses has gained international acceptance. The profile is tilted and closed manually or by machine, using shaping machines. It is even possible to produce special shapes such as convex and concave curves or conical course without difficulty. The multitude of possible detail variations in the dual standing seam offers a subtle emphasis of shape and looks equally appropriate with both traditional architecture and modern designs.
