Cast Iron Rectangular Pipe

About Cast Iron Rectangular Downpipe

Cast iron rectangular downpipe is a traditional angular profile drainage pipe found on grander Victorian and Edwardian properties, public buildings, and commercial premises. The rectangular profile gives a more formal, structured appearance than round downpipe and was commonly paired with Victorian ogee and moulded ogee cast iron guttering on larger properties. Supplied primed and ready for painting.

When to Use Rectangular Downpipe

Choose rectangular over round downpipe when replacing existing rectangular cast iron downpipes on a period property and you want to maintain the original appearance, when the property has rectangular pipe ears already built into the masonry, when the conservation officer specifies rectangular to match the original installation, or when the rectangular profile suits the architectural style of the building. Rectangular was common on larger Victorian townhouses, public buildings, churches, and commercial premises.
