The Pool Cover Profiles are executed in PVC or PC (polycarbonate) which is remarkably light and solid. They require little maintenance and are weather- and waterproof. The slats ensure a more buoyant force. A small barb prevents the profiles from bending under the pressure of extra weight. The polycarbonate slats are exceptionally hail and impact resistant. This profile is tested according the norms of the Swiss official institute VKF, in which it obtained hail class 5. Therewith the load capacity of this profile is by far the highest in the market.
