Open Mesh Steel Gratings consist of a number of Flat Bars (aka Main Bars or Load Bearing Bars) which are sat on their narrowest edges and are held together by a twisted wire which runs at right angles (aka Transverse Bars).

Construction |
The strength of the grating is determined by the Thickness of the Bearing Bars, The Depth of the Bearing Bars
and how far the Grating is required to 'Span'. It must always be observed that the Ends of the Bearing Bars must be supported at each side. The diagram below shows Two Universal Beams with the Bearing Bars running between the Two, and it is this that gives Open Mesh it`s strength. Turning the grating at right angles would result in the small twisted wires taking the load and this could prove to be fatal. It is always important to check but especially when gratings are
made in 1000 mm x 1000 mm Square Panels. Please see load tables in our brochures or call to discuss your requirements, we will be happy to help.
