Round 100mm Black Cast Iron Downpipe

100mm Round Downpipe is mainly used with larger sizes of gutter such as 125mm and 150mm due to the higher flow rate. 

This is the factory black painted option, alternatively you can choose our primed option if you wish to paint the gutter in a colour of your choice.

In contrast to most PVC downpipe systems, cast iron rainwater pipe and its assorted fittings is vastly more ornamental. With conventional eared sockets, a broad variety of bends and a plentiful range of decorative hopper heads, our cast iron pipes can make any property stylish. 

Our cast iron systems are provided by Hargreaves, a long-established foundry located in Halifax, Yorkshire. They have been casting iron goods since the 1880’s, and furthermore are the number one supplier of Cast Iron gutters in the UK market. With all of their years of casting experience, we also offer the option of custom manufacturing if needed for more wide-scale projects - for more details, please contact us.
