Pressed Gratings type RR
The pressed gratings are manufactured of solid strip steel bearing bars and crossbars to form a sturdy
grid. Dimensioning is very precise thanks to the sophisticated, computerized production process in which
the strip steel is unwound, straightened, punched and cut off extremely accurately. The bearing bars are
automatically pressed into the crossbars and enclosed by an edge, which ensures stable joints.
