Expanded Metal Raised Vs Flattened

Standard expanded metal mesh is expanded metal as it comes off the press.

Expanded metal raised vs flattened.

Raised expanded metal also referred to as standard expanded metal is the format of steel aluminum or stainless steel after it has been put through the expanding press. Ordered correctly a 4 x 8 piece of mesh would look like the reversed diamond orientation piece you see to the right. The strands of standard expanded metal are angled rather than fixed on a horizontal plane which makes the material less smooth than its flattened counterpart. There are standard expanded metal styles and numerous variations in strand width and opening sizes can be produced to create whatever architectural or industrial pattern is required.

Flattened expanded metal on the other hand may be more useful for certain parts handling applications or for making larger custom mesh baskets slightly lighter by thinning out the. I finally a note about flattened expanded metal. For fencing purposes expanded metal is ordered swd x lwd. The raised configuration adds rigidity and anti slip resistance to the mesh.

Flattened expanded metal flattened expanded metal is manufactured by passing the standard expanded metal through a cold roll reducing mill providing a flattened surface and. Standard expanded metal sheets are passed through a cold roll reducing mill parallel to the diamond pattern lwd to form flattened expanded metal. It is a finished product as it comes from the press. Expanded metal is manufactured in 2 ways flattened and raised.

The shearing and stretching of the expanding process creates strands and bonds that are set at a uniform angle to the plane on the sheet. By flattening the sheet the bonds and strands are turned down to produce a smooth and flat surface reducing the overall thickness and elongating the diamond pattern. This makes the expanded metal mesh thinner flatter and wider longer. Flattened expanded metal is what results when standard expanded metal is put through a cold rolling steel mill to flatten the expanded metal mesh out.

Also named standard expanded metal. Because it is sometimes difficult to predict how much expansion will occur in the mesh during the flattening process. Expanded metal sheet is made by first creating multiple slits in the sheet and then stretching the sheet. Expanded metal is also produced in a flattened form which is created by rolling standard or raised expanded metal.

These raised strands can be flattened later in the process if desired.
