The rainwater downpipe set for your Biohort storage shed drains the rainwater from the roof. This will reduce washout of concrete slabs and above-average water accumulation during rainfall around the storage shed. The rainwater downpipe set for your storage shed contains two rainwater downpipes, each fitted with an outlet elbow to control the direction of the flow more efficiently. It is made from galvanised, polyamide enamel coated steel plate. The fixing material is supplied.
