Expanded Meses
General Characteristic
Figures 1 and 2 show the general geometry of Raised and Flattened mesh sheets. As mentioned before, the Raised sheets are the first step of manufacturing the product and through another process is converted to Flattened sheets.
Each type possesses a multitude of uses, some of which are shown in Table 3.
The specifications of expanded metals are shown in Table 2.
Each type possesses multiple usages, some of which are shown in Applications.
The specifications of expanded metals are shown in Table 2.
Definitions
Strand Width
The width of sides of mesh units or diamonds.
Strand Thickness
The thickness of sides of mesh units or diamonds.
This thickness is equal to the thickness of the raw material sheet.
Bond
The intersection of two strands is called the Bond. Its width is always double that of the strand width.
SWD
The axis – to – axis distance between two consecutive Bond which is measured across the longest side.
LWD
The axis – to – axis distance between two consecutive Bond which is measured across the longest side.
SWO
The inside-to-inside distance of two consecutive Bonds which is measured across the shortest side.
LWO
The inside-to-inside distance of two consecutive Bonds which is measured across the longest side.
Overall Thickness
The actual measurement of the thickness of the mesh measured at the Bond.
In Flattened mesh, the value of the overall thickness is equal to the strand thickness.
Open Area
The approximate percentage of the opening and extension of the mesh relative to the raw material sheet.
Gauge
A number which has been defined based on the thickness of standard metal sheets. Further details are shown in Table 1.
