A slotted grating is a type of grating for drainage channels offered by HAURATON. The term describes the shape of the inlet openings. Slotted gratings consist of ductile graphite iron, galvanised steel or stainless steel. The grating has transverse slots that allow the water to run into the channel from where it is discharged. Slotted gratings are used in many applications. They are available for different types of channels and in different nominal widths.
