polymer drainage channel EN 1433 a.Flat surface and slope bottom b.Small structure,which can help smooth the draining c.Convenient to transport and easy to intall for these high-strength and light-weight products d.High resistance against heat,acid,alkali,freezing and thawing e.Flexible to be installed according to the length of the i f.Able to adjust the slope face according to the position of the drainage hole e.Self-cleaning function as the interior is u-shaped and slightly sloped With this new polymer concrete chnnel with incroporated slope,a considerable saving is achieved in terms of maintenance costs for the installations,marking hunman intervention almost unncessary.The same water that flows through the channel sweeps the elements that could have remained.
