Bearing Bars
Load bearing parallel bars between two grating supports.
Cross Bars
Connecting bars welded and/or pressed into and across bearing bars
at 90°.
Banding
Banding is on all sides, normally the same height as bearing bars
(in direction of bearing bar = banding along side, cross to bearing
bar = cross banding).
Mesh
The distance between bearing bars and cross bars measured as clear
space.
Length
The external distance of a metal grating in the direction of bearing
bars. Always expressed as length even if less than the width.
Pitch
The distance between bearing bars and cross bars measured centre-to-centre.
Width
The external distance of a metal grating in the direction of the
cross bars. Always expressed as width even if greater than the length.
Span
The distance measured from centre to centre of support. Clear span
or effective span is the clear distance between two supports.
| Cutouts
Straight or curved cutouts in metal grating are sometimes necessary.
After cutting out, gratings should always be re-banded.,
Small Cutouts
Straight or curved cutouts with a length of less than 0.5mm.
Kick Flat
A band protruding above the grating. Should always be a minimum
of 100mm higher than the grating top.
Support
The designed length of the supports must be a minimum of 30mm.
When erected, the support length must be a minimum of 25mm. However,
deviations are allowed in cases of constructive precautions that
prevent a shifting of metal gratings in load direction.
Serration
Notching the bearing bars creates improved serration on forge welded
gratings.
Perforated Metal Planks
Produced by forming and perforating sheets. Different patterns,
widths and heights are possible depending on the application.
