Expanded metal is a sheet of metal fabricated with a regular pattern of diamond-shaped openings. These openings reduce the weight and cost of the sheet and provide ventilation, making it a versatile solution for many applications. The most common metals used for expanded metal sheet include steel, stainless steel, and aluminum, although it is also made from titanium and copper.
Expanded sheet is made from a single sheet of metal that has been slit by a row of knives mounted on an industrial die cutting machine. The knives move back and forth in a uniform pattern, slicing the sheet in alternating cuts, while the sheet moves through the machine.
As the knives cut, they simultaneously push down on the newly cut sections, stretching them apart into “ribbons.” The ribbons remain attached at the uncut sections, which become the corners of open diamond shapes in an expanded mesh sheet. The size, shape and positioning of the knives and the thickness of the metal sheet can be changed to create openings of different dimensions for a variety of applications.
There are various types of expanded metals and here are the most common types:
The most flexible and effective price stability of the product is Standard expanded metal. It’s available in a range of gauges and open sizes. It’s frequently used to create a stiff, lifted, and slip-resistant base. The strands and bonds of normal extended metal are all set at the same angle. This adds power and rigidity while still allowing for optimum airflow.
Flattened expanded metal is made through flattening expanded metal through cold rolling it. Where a smooth surface is desired, it is chosen. The flattening mechanism usually extends the duration of the sheet by 5 percent.
Instead of the regular diamond openings, hexagonal extended metal has hexagonal openings. The metal’s hexagonal form adds strength while allowing air, light, fire, sound, and liquid to move through. When the metal is extensively extended, hexagonal openings are favored as diamond openings.
The diamond design is enhanced with architectural elements in an architectural extended alloy. As a result, the architecture achieves a balance of good looks, increased protection and privacy, and better ventilation. It may be used for both utilitarian and aesthetic purposes and a mix of the two.
Micro stretched metal is a light gauge metal with small holes. Regular, flattened, hexagonal, and square openings are all possible. Sensors also use this kind of expanded aluminum.
Specially designed expanded metal mesh for use in architectural and decorative applications.
These designs can be used to provide privacy and to control light and air while allowing visibility.
Sunscreens, room dividers and building facades are only a few of the possible design possibilities.
Available in carbon steel, aluminum and other alloys in a wide range of patterns and gauges. Most of these patterns are produced on a special order basis only.
There are various benefits of using expanded metals
● Fair Cost: A little number of metals also can be expanded into big pieces
● Efficient Process: Very less waste is obtained while processing the expanded metal
● Good conductor: Expanded metal is a good conductor of energy, magnetic flux, and heat since it is a single piece.
● Protective reinforcement: For additional strength, expanded metal meshes may be mixed with glass, concrete, and other materials.
● High tensile strength: Expanded metals can handle more weight and sustain more stress than woven metals or jointed welds.
● Light weight: Expanded metals are thinner than standard metal sheets.
● Allows for free movement of air and light: Metal that has been expanded allows for free movement of air and light.
● Acoustic characteristics: Specifically designed mesh may improve acoustics while also providing sound deadening material.
