Square & Rectangular Cast Iron Downpipes

Square and rectangular cast iron downpipes are generally less common than their round counterparts. However, they pair beautifully with the sharply featured, decorative moulded ogee profile gutters. Together these make them a great choice for projects that require a distinctive architectural style. Their unique shape can enhance the overall aesthetic of a building, adding a distinctive character while still providing effective drainage. As such, they are often selected for use in traditional and period-style properties, and where attention to detail these is key.
