These channels are used for collection and drainage of rain water and for the discharge of liquids for industrial use. The material used is HDPE (High Density Poly-Ethylene) which has excellent resistance to chemicals and organic agents and is self-cleansing. These channels are shock resistant, unbreakable and can guarantee high performance even in the presence of thermal shock (from – 40°C to – 100°C). They can be combined with a wide range of gratings in order to be used in pedestrian areas, driveways, roads and highways.
