Expanded Metal Diagram

SWD

The distance from a point on a bond to a corresponding point on the following bond measured across the SHORT WAY of DIAMOND.

LWD

The distance from a point on a bond to a corresponding point on the following bond measured across the LONG WAY of DIAMOND.

BOND

The intersection of two strands.

SWO

SHORT WAY of OPENING, the distance measured from the inside of the bond across to the inside of the bond SWD.

LWO

LONG WAY of OPENING, the distance measured from the inside of the bond across to the inside of the bond LWD.

STRAND WIDTH

Amount of material fed into the press to produce one strand.

STRAND THICKNESS

In standard, it is the gauge of the base metal. In flattened, it is the overall thickness of the finished sheet.

STANDARD

Also called regular, unflattened, or raised expanded metal. Expanded metal as it comes from the press. The strands and bonds are set at a uniform angle to the plane of the sheet.

FLATTENED

Standard expanded metal that has been passed through a cold roll mill. Bonds and strands are turned down to produce a smooth surface.

SHEARING

Cutting expanded m etal to size to produce various sizes and shapes.

MACHINE RUN TO SIZE

Expanded metal as it comes off the press with closed diamond edges.

RANDOM SHEARING

Expanded metal cut to size leaving open diamond edges.

BOND SHEARING

Expanded metal cut to size leaving closed diamond edges.

Short Way of Diamond

Optional diamond direction

Can reduce your cost up to 25%. Our dual production capability allows us to produce lengths in either the short way of the diamond or the long way of the diamond.
