Self cleaning water gutter for tracks over fields and meadows. Made of guard rail steel (S235) with a free flow profile and welded brackets beneath to give extra hold in the ground. Extremely smooth surfaces increase flow on a minimum gradient which in turn reduces the length of the guttering required. Depending on the slope, the following distances between channels are recommended: 5% - 60 m, 7% - 50 m, 10% - 30 m, 14% - 20 m, 16% - 15 m. Install at an angle of 70-80° to the track's direction with a 50 cm overhang to avoid under wash. In situations where heavy vehicles drive over the channels frequently, it is best to surround them with skimmed concrete.
