Round and rectangular steel downpipes with brackets, bends, shoes and offsets.
Profile cross-section — schematic, not to scale
Overview
Downpipes in round and rectangular sections, with the bends, offsets, brackets and shoes needed to get around eaves overhangs and down to a drain or soakaway.
Wall brackets are specified against the substrate — masonry, timber or a ventilated cladding cavity, where the fixing has to reach past the insulation without bridging it.
Applications
- All rainwater installations
- Ventilated facade fixings
- Ground drainage connections

On-screen colours are approximations. Coated steel changes appearance with gloss level, surface texture, viewing angle and daylight. Always confirm a colour against a physical VANKKA sample before ordering.
