Expanded metal offers an excellent combination of strength, resistance, cementation, oxidation and thermal shock useful for various applications in the thermal processing sector. Fratelli Mariani are among the most prepared producers of expanded metal (expandedmethalmesh) and offer a wide range of types suitable for each use.
This material is produced through a cold sheet metal deformation process, through which regular openings and lights of different shapes and sizes are obtained which allow the passage of air, liquids and light.
Expanded metal is a functional material that can be easily customized according to the various technical and aesthetic requirements. Several expanded metal dimensions are available: in rolls or sheets. Both can be used according to standard or specific measures. The width and shape of the mesh, in fact, depend on the use and specific needs. It is also a robust and solid material that does not fear wear.
Micromesh – Micro expanded metal mesh
The expanded metal mesh is suitable to be used both for filters and for other applications. It can be considered a particular expanded metal whose peculiarity is the small size of the mesh. It is a type of special expanded metals, made of thin sheets of metal. The expanded metal mesh, with its thinner dimensions than the classic metal mesh, is used as a replacement material for the filter sheets. It is suitable for use in different fields due to the small size of the mesh, which makes it a particular type of metal.
Usually the micromesh are produced in iron, stainless steel, aluminium, peralluman, brass, copper or plastic material.
Rhomboidal Mesh
The rhomboidal mesh is the most commonly used expanded metal model. Its diamond shape allows a good passage of air and light and gives it a good aesthetic appearance.
Round mesh
The micro expanded metal with round mesh is a valid alternative to perforated sheet metal with the advantage that it has no production waste.
Squaremesh
The sqare mesh expanded metal is a type of mesh where the long and the short way diagonal are the same.
Hexagonalmesh
Hexagonal expanded metal has hexagonal openings instead of the usual diamond ones. The hexagonal shape gives the metal extra strength while allowing the passage of air, light, heat, sound and liquid. Hexagonal openings are preferred over diamond openings when the metal is heavily expanded.
Heavymesh
The reinforced expanded metal is particularly suitable for applications where robustness is required.
Characteristics and use of expanded metal
These are decidedly versatile elements, which thanks to their universality can easily be used in various sectors: from industry to agriculture, from construction to furnishing.
The fundamental element is the hole, whose shape varies according to the specific cases and the types of use required. All the holes, regardless of their shape, have the same size throughout the sheet. Each perforated metal is therefore the result of a precise production technique.
The resistance that characterizes these products allows a relevant use in construction and carpentry. In industry, stretched nets comply with current accident prevention and anti-slip regulations. Partition walls can be built to protect the perimeter of some areas, walkways and structures suitable for protecting machinery in operation: the most suitable grid will be chosen for each use.
Moreover, they are perfect for obtaining a practical and effective shielding, as well as for being used in industrial environments when working with very powerful acids. They can be used, for example, in contact with industrial acids, thanks to their high degree of resistance to corrosion.
