Industrial Gutter

Our 170mm Industrial Guttering system is ideal for industrial, agricultural and commercial buildings. It is generally suitable for any building with a large roof area. The flow capacity of the system is much greater than most 150mm systems on the market. In addition to FloPlast's Xtraflo system, we also stock a 170mm (150mm Internal) Galvanised Steel system.


  • The vortex outlet design encourages the 'swirling effect' of the water for greater water flow down the pipe
  • Fittings come complete with wide rubber seals which allows for optimum performance in all conditions
  • Innovative and clean modern appearance
  • Semi-Elliptical profile
  • High flow capacity - 11.8 litres/second, outlet in centre, 1.350 fall (much greater than most 150mm rainwater systems)
  • Connects to 110mm pipe and fittings
  • System is covered by a BSI Kitemark - no. KM501316
  • Silicone lubricant must be used on all installations (SL400)


Most commercial guttering systems are 150mm (6”). Floplast’s XtraFlo system is a 170mm gutter across the top by 108mm deep. This gives it an extremely high capacity and flow rate.

Galeco's 135mm square gutter is perfect for steeply pitched roofs. It also features an insert on each fitting which adds additional pressure to compress the gutter onto the seal. This ensures that full contact is made all the way around the seal section.

High Capacity

FloPlast's Industrial gutters flow capacity varies between 4.3 litres per second (fixed level with the outlet at one end) and a huge 11.8 litres per second (fixed at 1:350 with a central outlet).

We appreciate that these stats can be baffling to all but scientists and architects, but what this essentially means is that the Industrial Gutter can hold approximately five times as much water as our standard half round guttering system and over twice as much as our standard Deep Flow Gutters.

It can handle the most intense amount of rain from any kind of roof, including domestic, commercial, and industrial. Additionally, it can manage rain from office and apartment complexes.

Galeco's square gutter system fills a gap in the market, up until now deep gutters have been either half round or semi-elliptical in design.

Galeco's 135mm system is applicable to modern and traditional building designs. It is suitable for both residential and commercial buildings.

Barn Gutters

Industrial Gutters are ideal for use on barn roofs. The profile of Xtraflo gutter is deep and oval, and its width is 170mm. This is ideal for collecting large amounts of water. We speak to many farmers (and developers working on barn conversions) who are in the process of replacing old asbestos or metal gutters that are just not fit for purpose on buildings with roofs of this size.

The “fit and forget” nature of PVC combined with the superior dimensions of our industrial guttering makes it the ideal gutter system to be fitted to barn roofs. All that is required is a wash-down with soapy water once or twice a year.

Fascia Brackets

Due to the heavy weight of water that a fully laden XtraFlo Gutter can carry, fascia brackets should be spaced at 600mm intervals. This means that you should allow approximately 7 brackets for every length of gutter that you purchase. Any stop ends should also be supported by a fascia bracket within 150mm of the fitting.


Our half-round Industrial Guttering system uses 110mm downpipes, which are compatible with all BS Approved Drainage Systems. Offsets (swan-necks) are achieved by the use of SP440 and SP435 top and bottom bends. The downpipes should be secured with clips at intervals of no more than 1.8m.


Like other profiles of plastic guttering, industrial is simple to install. Please visit our Industrial Gutters Guides & Tips section for videos, technical documentation and PDF guides.
