Expanded metal is a sheet of metal fabricated with a regular sample of diamond-formed openings. These openings reduce the weight and cost of the sheet and provide air flow, making it a versatile answer for a lot of applications. The commonest metals used for expanded metal sheet embrace metal, stainless steel, and aluminum, although it can be made from titanium and copper.
How is Expanded Metal Made?
expanded metalExpanded 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 sample, slicing the sheet in alternating cuts, while the sheet moves by way of the machine.
As the knives reduce, they simultaneously push down on the newly reduce sections, stretching them apart into «ribbons.» The ribbons remain attached at the uncut sections, which develop into the corners of open diamond shapes in an expanded mesh sheet. The dimensions, shape and positioning of the knives and the thickness of the metal sheet may be modified to create openings of various dimensions for a wide range of applications.
Types of Expanded Metal
Expanded metal sheet comes in different profiles, together with:
Standard Expanded Sheet: A completed product as it comes off the press after being minimize and expanded. Often referred to as raised expanded metal, due to the alternating ridges shaped by overlapping metal strips.
Flattened Expanded Sheet: A standard expanded sheet that is then cold rolled, leaving a flat, smooth surface. Flattened expanded sheet is about 5% lighter than commonplace expanded sheet.
Expanded Metal Grating: A heavy duty expanded sheet manufactured from carbon metal sheet or plate. Expanded metal grating has no joints or welds, as every sheet is a single piece of sturdy steel. Ideal for catwalk and platform applications.
A Versatile Product
Expanded sheet metal is a flexible and economical product that is durable, straightforward to work with, and provides low wind resistance. It gives one-piece development that won’t unravel under regular circumstances, and can hold its shape for many years. The strands and bonds of the diamond-formed trusses add energy and rigidity.
It is commonly used in a wide range of applications, corresponding to:
Machine guards
Catwalks, platforms and stair treads
Grating/flooring
Stair and balcony railing mesh
Window security
Vents
Conveyers
Shelves
And much more
