Bond Side Shearing:
This cut is made along the length of the sheet on the center line of the bond
over the specified length. In most cases it is not practical to attempt to
Bond Side Shear either regular or flattened expanded metal, because of camber.
End Shearing:
The process of cutting a piece of expanded metal parallel to the short way of
the diamond.
End Random Shearing:
The process of shearing a piece of expanded metal to a specified length (LWD).
This cut normally leaves open diamonds at both ends but accomplishes close tolerance
(plus or minus 1⁄8”) when both ends are sheared.
End Bond Shearing:
The process of shearing a piece of expanded metal to a specified length (LWD).
A plus or minus 1⁄8” tolerance applies when both ends are sheared.
One end is cut on the Bond parallel to the SWD, the other end usually has open
diamonds. NOTE: When End Bond Shearing is requested for both ends, the sheet
is sheared at the center line of the bond over the specified width. A tolerance
minus 0 plus 1⁄2 diamond applies. It is possible to End Bond Shear, but
extraordinary care must be exercised to maintain the squareness of the sheet.
Random Side Shearing:
Side shearing is a cut made parallel to the LWD dimension of the sheet which
usually leaves open diamonds. Standard tolerance SWD is plus or minus 1⁄8” when
both sides are sheared.
Side Shearing:
The process
of cutting a piece of expanded
metal parallel to the long dimension of the diamond.
Squareness:
When all four sides of a sheet of expanded metal
are sheared, the maximum tolerance will be plus or minus 1⁄16” per
foot of width.
