Terminology, Press-welded Grating

Load bearing bar

Upright positioned flat bar gives the load bearing capacity to the grating.

Cross bar

Bars connect the load bars at right angles (connected by press welding).

Grating, serrated design

Load bearing bar with serrated top face for extra non-slip safety.

Mesh opening

Distance between load bearing bars and cross bars (centre to centre).

Grating length, span width or length of load bearing bar

Length of grating = length of load bearing bar including edging bar Span width = the distance between two support beams The grating can be laid over two or more support beams. On the drawing the load bar direction is marked . The first figure of the panel dimensions indicates the load bar measure, e.g. 815 x 1000 mm.

Grating width Length of cross bars

Width of grating = length of cross bars.

Grating height

Grating height = height of load bearing bars.

Matching cross bars

Panels can be laid out with matching cross bars. Supplied at an extra charge.

Edging bar

Flat bar welded to the ends of the load bearing bars connecting them together.

High edging bar (kick strip)

Edging bar higher than the load bearing bars, projecting above the top of the grating panel.

Low edging bar

Edging bar wider than the load bearing bars, projecting below the bottom of the grating panel.

Opening measure

The actual measurement of the opening for positioning of the grating panel.

Panel measure

The exact measure of the grating panel - must be 6 - 10 mm less than the opening measure. Applies to both the length of the load bearing bars and the length of the cross bars.
