Technical Information
Kyowa Filter Unit are large corrosion-resistant nets manufactured from highly durable synthetic mesh, which Ridgeway can supply ready filled for delivery to your site. For more information on this and to learn about the filling process click here.
The S Type is suitable for use in marine environments - it is manufactured using a nylon double mesh and has been designed to withstand the impact of strong current flow. It is available in 2-8 ton sizes.
Porous construction creates a natural habitat for small fish and other marine species. This characteristic also prevents the suction that can occur where solid units are employed in an area with strong currents. The construction of textile mesh filled with small rocks allows for a smaller load compared to the use of concrete or rip-rap materials.
