Offshore-gratings
Offshore-gratings (O-SP-SS)
As its name suggests, offshore grating was originally developed for use on offshore oil rigs.
Basically a press welded grating, it is strengthened by round bars welded beneath the twisted cross bars and in the same direction as the bearing bars. See the photo to the Left.
Mesh spacing:
30 x 19mm with a round bar welded beneath so that a test ball 15 mm in diameter cannot fall through.
Bearing bar measurement:
20 x 3mm up to 60 x 5mm
