Metal grating

press weldedweldedrugged

Product information
This press-welded grating is designed for offshore oil and gas platforms. It is manufactured so that a 15 mm diameter test ball cannot pass through the mesh. To ensure this, an intermediate round bar is welded centrally and parallel between the bearing bars to the underside of the twisted square cross bars by automatic resistance welding, providing increased stability for severe offshore conditions.
