What is expanded metal mesh ?

Expanded metal is an extraordinarily versatile material - one
with thousands of uses. It comes in four basic types, and it
has four primary areas of application.

Basic types are raised (or standard), ?attened, Gridwalk,
and architectural (or decorative) meshes. The major areas
of use are for enclosure, protection, support and decoration.

Expanded metal products are produced from solid sheets
or plates of carbon, galvanized and stainless steel, as well
as aluminium and a variety of alloys of copper, nickel, silver,
titanium and other metals.

In an expanding process, the sheet or plate is
simultaneously slit and stretched longitudinally - expanding
the slits into diamond-shaped holes of uniform size, shape
and regularity.

No metal is lost in the expanding process. Moreover, the
final product is stronger per kilogram and lighter per metre
than the original sheet or plate. The strands and knuckle of
the diamond-shaped trusses form an angle to the original
plane of the sheet, adding strength and rigidity.

Because it is made from a solid sheet of metal, it can
never unravel. The slender metal strands forming the open
diamonds permit light, heat, air, liquid and sound to pass
through - yet present a virtually impenetrable barrier to
intruders. Even if cut at one or more points, the remaining
strand intersections continue to hold.

Expanded ?

A range of materials are expanded on site from platinum to a fine guaze for jewellery to 6mm plates of steel for offshore walkways. Plastics, Aluminium, copper, brass, stainless steel, in fact any ductile metal can all be expanded in a range of material thickness and to a broad choice of patterns to suit specific applications.
