Staco - Model Type RR -Pressed Gratings
Pressed gratings are sturdy grids of bearing bars and crossbars made from steel strip. The sizes are extremely precise thanks to our sophisticated, computerised production process that also ensures the accurate coiling, straightening, punching and cutting of strip steel. The crossbars are automatically pressed into the bearing bars and enclosed by an edge, guaranteeing a rigid panel. As standard the V-edge is used, but it is also possible to choose a flat edge or T-profile edge.
