The process of cutting a piece of expanded metal parallel to the long dimension of the diamond.
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 1/16″ when both sides are sheared.
Bond Side Shearing
This cut is made along the length of the sheet on the center line of the bond over the specific width. In most cases it is not practical to attempt to Bond Side Shear either standard or flattened expanded metal, because of camber.
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 the specific length (LWD). This cut normally leaves open diamonds at both ends but accomplishes close tolerance (plus or minus 1/16″) when both ends are sheared.
End Bond Shearing
The process of shearing a piece of expanded metal to the specific length (LWD). A plus or minus 1/16″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 at the center of the bond over the specific length. A tolerance minus 0 plus ½ diamond applies. It is possible to End Bond Shear, but extraordinary care must be exercised to maintain the squareness of the sheet.
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.
The following information should always be included when placing an expanded metal order.
- Specify the number of pieces wanted.
- Specify the nominal width of the diamond SWD.
- Specify the style of the sheet. Example – #18, #9, or if aluminum, .081, .051, or if grating, 4lb., 5lb., 3.14lb., etc.
- Specify whether standard or flattened.
- Specify the type of metal wanted -Example – Carbon steel, stainless steel, aluminum, etc.
- Specify the size of sheet wanted –Example – 4′ SWD x 8′ LWD
Here is an example that illustrates the information necessary to fill your order without delay:
Example: 20 pieces ½” #13 standard carbon steel expanded metal 4′ SWD x 8′ LWD
