Technical Data
Expanded metal is a sheet of metal that has been slit and drawn into an open mesh pattern in a single operation. The resulting expanded metal mesh is stronger and lighter than the original metal sheet. It can be found in most industries in all shapes and sizes.
Our entire stock range is viewable in either tabular form or as individual mesh data sheets with actual size mesh photographs to aid your selection.

Tuffex supply three types of mesh:
Raised expanded mild steel mesh
Flattened expanded mild steel mesh
Walkway expanded mild steel mesh
We also supply Edging Strips suitable for all our mesh.


Understanding mesh dimensions
When ordering mesh it is important to understand the different ways that dimensions are measured on raised and flattened mesh.
The diagrams below show you the differences:

How to specify your sheet size
Longway (LW) is the dimension of the sheet measured in line with the longway of the diamonds, and should always be the first dimension quoted.
Shortway (SW) is the dimension of the sheet measured across the shortway of the diamonds, and should always be the second dimension quoted.
The diagrams below show you the difference:

This sheet is 1220mm LW x 2440mm SW
This sheet is 2440mm LW x 1220mm SW

General Technical Data
Tuffex is manufactured to BS 405, 1987 from a single sheet of steel with either raised or flattened strands.
All sheet sizes are nominal and sheets are normally supplied oversize and not sheared to the exact size unless agreed otherwise at the order placement stage.
The sheets are lightly oiled as part of the manufacturing process and to protect them from corrosion.

Following the industry convention, on raised meshes the Longway (LW) and Shortway (SW) dimensions are measured from the centre of each knuckle (joint), whereas on flattened meshes the dimensions are given for the aperture.

By convention, sheet sizes are stated with the Longway of the diamond running along the first dimension.
For example, 2440 x 1220mm indicates that the Longway runs down the 2440mm dimension
Whereas, 1220 x 2440mm indicates that the Longway runs down the 1220mm dimension.
