A pressed grating is manufactured by joining two crossed crosswise by means of press-fit assemblyThe separating plate is fitted into the supporting plate to form a stable and uniform assembly.
A welded grid is based on the same plate-plate concept, but incorporates welding to form a single body. In this type, not all intersections are weldedare not welded, but welding is performed is welded diagonally and spacedspaced, which provides elasticity and helps to avoid breakage when the grid is working under load.
