Expanded metal:
Raised Mesh
SWD: Plus 1/4" minus 0" per foot of width
LWD: Plus 3/4 minus 0"
Flattened Mesh
SWD: Plus 1/4" minus 0" per foot of width
LWD: Plus 3/4" minus 0"
Grating
SWD: Plus 1/4" minus 0" per foot of width
Camber
Measured by placing a straight edge along the concave side of the sheet parallel to the LWD, touching both ends. The maximum distance from the edge expanded metal to the straight edge is the camber
Raised Mesh
1/16" per foot of length
Flattened Mesh
3/32" per foot of length
Out of Square
Expanded metal sheets are not perfectly square as manufactured. Stock size sheets and machine run non standard size sheets will be produced to the following tolerances
SWD: 1/16" per foot of Width
LWD: 1/16" per foot of Length
Sheets that have to be perfectly square must go through a secondary process of shearing.
Flattening
Flattened sheet thickness shall be plus or minus 10% of published thickness or strand thickness
Non standard sheets
Machine run
