Perforated Metal Sheet is one of the most versatile and popular
metal products on the market today. Perforated metal not only helps
separate and screen solids, it diffuses light and air. If you are
manufacturing a product that needs to be lighter, considering using
perforated metal.
The perforated metal plate is a very special, highly utilized in
industry, construction, in the manufacture of various products
popular use such as garbage baskets, filters, etc. The wide variety
of sizes, as well as the different openings or holes offer the user
a wide range of options that will help to select the mesh precise
to their needs.
Materials: The most common material types are mild steel,
pre-galvanised mild steel, stainless steel, aluminium, brass and
some types of plastics.
Hole patterns: diamond, round, rectangular, scale, hexagonal and so
on.
Features of perforated metal compared with expanded metal: expanded
metal is similar to perforated metal, but it has been cut, rather
than punched, and stretched into a shaped framework. Materials out
of which expanded metal is made include sheets of steel, stainless
steel, aluminum, tin, copper and plastic. Flattened expanded metal
has been cold rolled to reduce thickness and increase surface
smoothness. Using expanded metal is an ecologically-minded
approach, as it is elaborated from discarded raw material. Expanded
metal is basically transparent, has high resistance and excellent
mechanical properties and is an excellent conductor. Expanded metal
can be made out of non-metal products such as plastic, which then
makes it an insulator.
Applications: Perforated metal is used in insulating the sound in
the municifal facilities, such as highway and railroad, the
material of the ceiling and wall to absor the sound, good shelves
in the market, decorative exhibiting and selling platform,
ventilate of grain depot. It is a valuable material for processes
of filtration, separation, equalization, compensation, among
others. The metal plates are used for separation of grains, food,
refrigeration, heating and air conditioning, grindings,
laboratories, etc.
