Expanded metal can be found in many industrial fields. When we have an inquiry of expanded metal sheeting, it is quite necessary to learn the expanded metal specification items. The materials can be chosen as your need, the common used specification can be as reference.
Actual dimensions SWD and LWD. Measured from a point to a corresponding point on the design shown.
The process of cutting a piece of expanded metal parallel to the long dimension of
RANDOM SIDE SHEARING
Side shearing is a cut made parallel to the LWD dimension of the sheet which usually
leaves open diamonds.
BOND SIDE SHEARING
This cut is made along the length of the sheet on the center line of the bond over the specified width. In most cases it is not practical to attempt to Bond Side Shear either regular or flattened expanded metal because of the camber.
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 when both ends are sheared.
END BOND SHEARING
The process of shearing a piece of expanded metal to a specified length (LWD). One end is cut on the Bond parallel to the SWD—the other end usually has open diamonds.
SIDE BOND SHEARING
When ordering Expanded Metals, give complete style specifications to avoid possible
error. Include style, standard or flattened, type of metal, and sheet dimensions. SWD
dimensions always given before LWD.
