Dimensions / Laying
Grating length = length of load bearing bar including edging. The span is the distance between two supports. The grating can be placed across two or more supports. When indicating the size the length of the load bearing bar is the first figure, e.g. 810 x 1000 mm.
Grating Dimensions
The grating dimension is the exact size of the grating panel. The aperture must always be 6 - 10 mm larger than the size of the grating (daylight measure). This applies to both the length and the width.
Width / Finishing Piece
The standard width of the grating is 1000 mm.To achieve the full laying measure a finishing piece is often required. Cut the finishing piece close to the next load bearing bar by which full edging around the grating is achieved. All cut faces have to be cold galvanized.
