Coperall 21 are highly versatile metal sheets with a symmetrical profile, designed for use in pitched, curved or vaulted roofing applications as well as for wall cladding.
On curved roofs with a radius = > 20m. Coperall 21 sheets will self-center.
Overlaps of just 1 and 1/2 profiles will ensure fast and cost effective installation works and will provide an excellent waterflow.
Coperall 21 profiled metal sheets are designed for roofing and cladding applications, mainly for industrial destinations of use.
