The BIRCO channel systems for surface drainage and discharge of aggressive liquids are made of concrete, steel, and PE, and cover a wide range of uses – from areas frequented by heavy-duty vehicles to roof terraces. In addition, BIRCO offers an infiltration system which allows the infiltration of stormwater with the use of only little space. Various cover versions are available for all systems. They include slotted cast gratings, cast mesh gratings, mesh gratings with various mesh widths, slotted and perforated gratings, as well as design-gratings such as the „Wave"​ and „Ellipse"​ cast gratings.
