The self-supporting curved roof system allows covering a school area with dimensions of up to 22 meters wide. The main advantages of a cover for a school playground are, mainly, protection against the elements; both in regions with high solar incidence and in those with high rainfall and frequent humidity. By being able to use this area independently of the weather, the continuity of the scheduled activities and the enjoyment of rest time outdoors is guaranteed. Another advantage is the protection of outdoor equipment and furniture, since being protected will prolong their useful life. In addition, the aesthetics of the arch add a visual contribution to the environment, generating a cozy and attractive space for families.
