Standing seam profile
As standing seam are multitudes designated with a special form of upper chords. The metal profiles are assembled at the place of use, on the roof or on the facade . When used on the roof, this type of roof covering is referred to as a standing seam roof or standing seam covering . The panels are made from metal strips ( coils ) in sheet metal thicknesses of 0.50–1.0 mm in a roll former with upper and lower folds . The production can be done either on a profiling machine in a factory or in a mobile system directly at the place of use. The mobile systems have the advantage that lengths of up to 160 m can be created.
In cross-section, standing seam profiles are similar to those of cassette profiles. The shares can be made from zinc , aluminum , copper , steel , stainless steel and especially from organically coated steel strips. The designation for the upper chords is differentiated depending on the type of standing seam formation. Standing seam profiles made of aluminum usually have flanges that interlock in opposite directions and are closed by machine after installation. Standing seam elements made of steel, stainless steel, zinc or copper are delivered with flat top chords in different widths and shapes and after laying are mechanically or manually rebated. The final state then describes an angled standing seam or more often a double standing seam. In the case of coils made of stainless steel, the longitudinal joint overlaps are closed using the roll seam welding process. The coils have overall widths between 305 mm and 600 mm with web heights of 50 to 75 mm. Most frequently, standing seam elements are used as roofing for double-shell metal roof structures. Occasionally, however, they are also used as wall covering.
Architectural and technical aspects of the installation
Standing seam profiles offer great aesthetic appeal. The linear design of the groups creates a uniform image, which is reinforced by an interesting play of light and shadow. The high degree of design freedom and the restrained effect of the roofing enable a clear approach to the design language of the building. With a conical shape over the length of the component as well as a concave or convex rounded shape, they offer variable options for sophisticated design. A standing seam construction serves the trend to achieve / create clear and unambiguous solutions in architecture. Here, noble, elegant surfaces come into play. This type of laying of sheet metal roofs has a more than 200-year tradition in building culture and requires a high level of manual skill in order to solve even the most difficult connection details permanently and functionally.
