How is expanded metal made?Expanded metal Sheet is produced from
metal sheet or roll through stamping and expanding, which forms a
wide array of diamond shaped openings with uniform sizes.Compared
with the traditional flat metal sheet, expanded metal mesh has more
notable advantages for its versatile applications.Owing to the
expanding process, the metal sheetcan be expanded up to 8 times its
original width, losing up to 75 % its weight per meter, and becomes
harder.So it is lighter, less expensive than a single metal
sheet..What is expanded metal?Expanded metal mesh types includes
raised expanded steel mesh (also called standard or regular
expanded metal) and flat expanded metal mesh.Raised expanded metal
mesh has diamond openings with slightly raised surface. Flattened
expanded metal mesh is manufactured by passing the standard
expanded sheet through a cold roll reducing mill, forming diamond
openings with flat surface.The form of the meshes is normally
rhombic but more shapes are available, such as hexagonal, oblong
and rounded. The size of the meshes varies from very small meshes 6
x 3 mm suitable for filters, to very large meshes 200 x 75 mm often
used for architectural applications.The materials most often
utilised for expanded metal are mild steel, aluminium and stainless
steel, but we also offer in other materials (brass, copper,
titanium, zinc, etc).The length and width of the sheet and the grid
parameters are always described according to the following

alternative to perforated metal.Opening style of expanded
metal:Advantage of expanded metal :The advantages of using
expanded metal are numerous and depend on the specific application.
Below we have listed a few of the reasons for selecting expanded
metal.Light and cost efficientIt is a great advantage that
expanded metal is not assembled nor welded, but always made in
one piece.No metal is lost in the expanding process, hence
expanded metal is a cost effective alternative to other
products.Because there are no strained joints or welds, expanded
metal is stronger and is ideal for forming, pressing and
cutting.Due to the expansion the weight per metre is less than that
of the original sheet.Due to the expansion a much bigger open area
is possible compared to other similar
products. Greater strengthThe three-dimensional shape of the
meshes is another advantage since the areas where the meshes
meet are strong and enable the material to stand a far heavier
point load than similar products or a flat sheet. Anti-skid
qualitiesSome patterns have a type of mesh with special qualities
that not only make the surface non-skid, but also give the expanded
metal water and wind repellent qualities. Ideal for secondary
operationsThe expanded Metal is ideal for secondary operations. To
save time and to help reduce your costs offers to handle the
secondary operations for you. It could be flattening, bending,
welding, hot dip galvanising, painting or anodising of the expanded
metal.Applications:The different types of meshes have different
degrees of strength since the open area and weight of each type can
vary substantially. Below we have listed examples of the many
situations where expanded Metal can be used with
advantage. The high strength and the anti-skid qualities
make expanded metal most
advantageous for:WalkwaysFootbridgesFootstepsRampsPlatformsand
similar applications.Expanded metal can also make an effective
barrier and is favourable for use in security/safety
applications to protect e.g. buildings, people or
machines. Expanded metal also achieves a sound reduction and
shielding effect, ideal for use in airports and bus
stops.Expanded metal is a very popular material for today's
architectural and industrial design and our many customers all over
the world use it for many other applications apart from those
mentioned above. Building / ArchitectureExamples of
applications in buildings where the use of expanded metal
will be a benefit:CladdingCeilingsFacadesSun
protectionFencingShieldingFor these applications the expanded
metal most commenly used has a rib width larger than
20 mm.Expanded metal can also be used for reinforcing concrete,
plastic, artificial materials or for acoustic panels.It also works
well as a decorative product where there is a requirement for a
coarse appearance.Agricultural and Industrial sectorsExamples of
