The cast iron grate is used in semi-slatted delivery pens. It is made of spherical cast iron with gaps of 10 mm, 13 mm and 16 mm. Ductile iron grids have a better "micro" roughness than plastic grids. The advantage is that the sow is better stabilized. There is a special type of grating with non-slip dents. The advantage is the optimal, solid surface.

Advantages:

• The slightly rough surface makes the grate non-slip
• T-shaped ribs ensure optimal slurry flow
• Large cleaning opening
• Hard, minimal surface
• Long service life - good for both the environment and economy
• Same bearing surface and height as for easily replaceable triangular slats
• Self-supporting = low installation costs
