Deepflow Guttering | Hi-Cap Gutter Running Outlet

Deep flow guttering is the ideal solution for buildings with large or steep roofs where higher rainwater capacity is essential. Designed to handle a significantly higher flow rate than standard systems, deep flow gutters reduce the need for multiple downpipes, improving both performance and appearance.

First introduced in the 1970s, deep flow gutter systems quickly became the preferred choice for high-capacity rainwater management. Today, FloPlast deep flow guttering is widely specified by architects and contractors thanks to its proven performance, durability, and cost-effective design.
