FloPlast is a well-established manufacturer and supplier of Plastic Building and Plumbing systems to the UK construction sector. They specialise in Roofline products with an extensive range of Rainwater systems, including the Half Round gutter.

With a max flow rate of 1.05 litres/sec for a gutter system installed with a 1:350 fall ratio (0.82 l/s if installed level), the Half Round gutter system, connected to a 68mm Round downpipe by a Stopend Outlet at the end of the gutter run, is suitable for a maximum roof area of 50m2 (40m2 if installed level).

If using a Running Outlet connected to a 68mm Round downpipe at the centre of the gutter run, the max flow rate of the Half Round system increases to 2.34 litres/sec, if installed with a 1:350 fall ratio (1.62 l/s if installed level), making it suitable for a maximum roof area of 113m2 (77m2 if installed level).
