Introduction of Expanded Metal Mesh

Expanded metal mesh is an intermediate raw material that allows light and air to flow freely through it and that has more rigidity than the sheet from which it was produced.

It is formed in an expanded metal mesh press and produced from any malleable metal sheet product. The plate, sheet, or coil is simultaneously slit and stretched into diamond-shaped openings. These openings are of uniform size and regularity.

Design Designations

Strands – The sides of the expanded metal meshdesign v

Strand Thickness – Thickness of the base material from which the sheet was produced.

Strand Width – Amount of metal fed under dies to produce one strand v

Strand Thickness and Width – Can be varied to create different openings. The width of the strand should equal or exceed the thickness of the base metal.

SWD – Nominal dimension, Short Way of Diamond v

LWD – Nominal dimension, Long Way of Diamond v

Design Size – Actual dimension SWD and LWD. Measured from a point to a corresponding point on the adjacent diamond. v

SWO – Short Way of Opening v

LWO – Long Way of Opening v

Bond – Where two strands intersect
