arcoPlus1000® is a modular corrugated system consisting of 3 coextruded polycarbonate walls, in 8÷12mm thickness, perfectly overlapping lengthwise and enabling continuous coverage and skylights filled gutter. Considering the linear thermal expansion of polycarbonate, to avoid cracks at the through fixings the recommended maximum length is 5,000 mm. Application: Panels laterally overlapping insulated corrugated metal roofing panels. Minimum slope 5%. For roofing, recommended minimum slope 7%. For curved roofing, components are manufactured with a bend radius of R.3.300mm or R. 6.000 mm.
