MAGNUS GROUP EXPANDED METAL

EXPANDED METAL DESCRIPTION

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.

The Magnus Group is a major stockist of all 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.

Expanded Metal can be manufactured in Mild Steel, Galvanised, 3cr12, Stainless Steel and Aluminium.

EXPANDED METAL TERMINOLOGY

S.W.M = Short way of Mesh:

This is the size measured across the short way of the diamond mesh from centre-to- centre of the joints.

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.

EXPANDED METAL TOLERANCES

SHORT WAY OF MESH:
Nominal
LONG WAY OF MESH:
(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.
