Expanded metal mesh is
a uniform material that doesn’t stretch. It is very easy to deal with expanded
metal sheet as it is highly slip resistant and its production is very
economical.
Over the years, the
use of expanded metals has been increased widely almost in all fields for
example electric equipments, acoustics, firing, automobiles, vessels, machine
shielding, road guards, buildings, households, shelves, bird cages and stands.
The expanded metals
are commonly made from steel plate, stainless steel, nickel, aluminium, silver,
titanium etc. The common uses of
expanded metals are in EMI shielding, jewellery, mechanical apparatus, filters,
chemical systems and more.
Basically expanded
metal is a intermediate material permitting the passage of air and light, it is
more rigid as compare to plan sheet from which it is made. It is fabricated from
malleable metal sheet or coil in the diamond shaped holes. These holes are in
equal size throughout the sheet.
The decorative
expanded meshes are made in smaller diamond sizes or equal openings.
The architectural
meshes are made with special shaped openings that offer supreme appeal for
architects and designers.
The special fine mesh
is an accurate, mini type of traditional expanded metal that is developed from
the different types of metals. The fine mesh can be flattened or raised and is
delivered in coil and sheet forms.
In order to order the
expanded metal, you need to specify the following designations:
Strands- It describes
the metal sides.
Strand Thickness- It
describes the thickness of
the expanded metal that is used to fabricate the expanded sheet.
Strand Width-Magnitude
of metal sent to dies to develop single strand.
Strand thickness and
width- It can vary to develop various holes. The strand width should same or
surpass the metal thickness.
How expanded metal
is beneficial
These sheets offer
natural percentage of openings. This magnitude or percentage can be adjusted to
contain the architect or the specific needs of designer. By altering the
pattern sizes or strand width, it is feasible to control the open area % hence
controlling the passage of air and light flow according to your application
needs. Moreover, the light flow can be limited by the orientation or pattern
pitch.
The set of uniform
angles of the threads and bonds treating as facets reflect or improve the
lighting. The expanded sheet has become highly demanding among the architects
as it offers special characteristic.
The expanded metal is
fit for a special style or design. The extent of angles and various types of
slits, stretches and indentions may also depend on application requirements. The
expanded sheets for architectural, decorative or traditional purposes are slit
and stretched into a durable and non-ravelling sheet. The metal twist that is
noticed during its expanding results into offering greater durability and strength
as compare to the original sheet of the raw material. The metal can be used for
aesthetic appeal in fact also for the structural features obtained.
An expanded sheet can
withstand 90 degree bend with ¼ inch in the radius in any direction without
cracking.
