WHAT IS EXPANDED METAL?
Expanded Metal is a rigid, non-raveling piece of metal that has been slit and expanded. In the expanding process, metal can be expanded ten times its original size, lose up to 80% of its weight, becoming stronger and more rigid. No material is lost in the manufacturing process.
Magnus Steel (PTY) Ltd is a major stockist of raised and flattened expanded metal. We are able to provide our customers with a variety of options which can be used for strength, utility, safety and durability.

L.W.M = Long way of Mesh:This is the size measured across the long way of the diamond mesh from centre-to-centre of the joints.
Strand Width:The size of the strand measured at right angles to its thickness.
Strand Thickness:The thickness of the sheet before the expanding process takes place.
L.W.M =(a) Not greater than 10mm: ± 1mm (b) Not less than 10mm and not greater than 50mm: ± 3mm (c) Greater than 50mm: ±5mm. Strand Width: ± 10 % Strand Thickness: Subject to Mittal’s tolerance, except for flattened types which shall be at least equal to the nominal original thickness of the material of manufacture within 20%, measured at the knuckle.
