Because it would be
impractical to manufacture and transport a single unit of steel mesh big enough
to cover an entire slab panel, mesh reinforcement comes in smaller sheets
instead. The standard size of a sheet is 2.4 x 4.8m, however this can vary.
Where one sheet ends and
another begins in a floor slab, it is necessary to make them overlap to ensure the
minimum required reinforcement is maintained throughout. To make the areas of
overlap less awkward to work with, most sheets have flying ends along two of
A sheet is placed on spacers when installed to hold it in place as the
concrete is cast around it. Mesh sheets are tied to one another with wire to
stop the mesh kicking up and potentially causing restraint.
