Expanded Metal--Terminology


 

 


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.
