The KIO grating is produced exclusively in 500×500 dimensions (clear span 400×400) and in class C250.
The shape of the grating is concave to allow for optimal collection of surface water.
Like all other KIOs, the grating is made of Kinext™ composite material, is customisable and includes a non-slip surface.
The slots with a width of 32 mm have been designed in such a way that the water outflow section is no less than 30% of the section set by the internal clear span, as specified in EN 124-1.
