TERMINOLOGY

S.W.D.	Short Way Diamond
L.W.D	Long Way Diamond
Bond	Area where strands intersect
Strand Width	Surface area of metal strips forming diamond
Strand Thickness	Gauge of material being expanded
Flattening	Flattened short dimension diamond parallel to rolls
Cross Flattening*	Flattened long way diamond parallel to rolls
Deburring	Mesh passed through wire brushes to remove burns
Levelling	Mesh roller levelled to reduce curving

* Cross flattening results in distortion of the diamond in expanded mesh.
