Seam roofing system
—
Seaming allows for the joining of profiled slabs via superimposing and folding of their edges.
The slabs are fastened to the substructure by using concealed clips.
It is also possible to apply double seaming for sloping surfaces ≥ 5% or angular seaming for roof slopes ≥ 47% .
The standard seam height is 25 mm.
