Most commercial gutter systems are 150mm (6”). Floplast’s XtraFlo system is larger – 170mm across the top by 108mm deep – giving it an astonishingly high capacity and flow rate.

 

Our 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 - and as such it can cope with the heaviest flow of rainfall from any type of domestic, commercial and industrial roofs, or office and apartment blocks.

 

XtraFlo Industrial Gutters are ideal for use on barn roofs – the deep oval profile and 170mm width is perfect for catching the large quantities of water collected by these types of structures. We speak to many farmers (and developers working on barn conversions) who are in the process of replacing old asbestos or metal gutters than are just not fit for purpose on buildings with roofs of this size. The “fit and forget” nature of PVC (all that is required is a wash down with soapy water once or twice a year) combined with the superior dimensions of our industrial guttering makes it the ideal gutter system to be fitted to barn roofs.  

 

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.

 

This 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.

 

There is a handy guide to choosing the right large gutter here, and we have also put together a short video on how to make a swan neck for Industrial Gutters.
