About Euroslot Kdss

Wedge Wire Technology

The wedge wire surface is obtained by combining v-shaped wires and supports that are resistance welded. Juxtaposed wires, suitably spaced, determine the filtering surface.

Our production capabilities enable this metallic structure to be manufactured either in the form of a cylinder (Ø of 21mm to Ø 956mm by 6 metres long), or in the form of flat panels (2800 mm along the slots × 4500 mm).

Our industry expertise and our modern manufacturing facilities mean we can adapt Euroslot Kdss screens to meet your specific requirements.
