What is Expanded Metal?
Expanded metal is a sheet of metal fabricated with a daily sample of diamond-formed openings. These openings reduce the burden and cost of the sheet and provide ventilation, making it a flexible resolution for a lot of applications. The commonest metals used for expanded metal sheet include steel, stainless steel, and aluminum, although it is also 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 slicing machine. The knives move back and forth in a uniform sample, slicing the sheet in alternating cuts, while the sheet moves through the machine.
As the knives minimize, they simultaneously push down on the newly reduce sections, stretching them apart into "ribbons." The ribbons remain hooked up on the uncut sections, which change 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 could be modified to create openings of various dimensions for a wide range of applications.
Types of Expanded Metal
Expanded metal sheet comes in completely different profiles, including:
Standard Expanded Sheet: A completed product as it comes off the press after being minimize and expanded. Typically referred to as raised expanded metal, as a result of alternating ridges shaped by overlapping metal strips.
Flattened Expanded Sheet: A regular expanded sheet that's then cold rolled, leaving a flat, smooth surface. Flattened expanded sheet is about 5% lighter than normal expanded sheet.
Expanded Metal Grating: A heavy duty expanded sheet manufactured from carbon steel sheet or plate. Expanded metal grating has no joints or welds, as each sheet is a single piece of sturdy steel. Ideally suited for catwalk and platform applications.
A Versatile Product
Expanded sheet metal is a flexible and economical product that's durable, straightforward to work with, and provides low wind resistance. It gives one-piece building that won’t unravel under normal circumstances, and can hold its shape for many years. The strands and bonds of the diamond-formed trusses add power and rigidity.
It's commonly utilized in a wide range of applications, comparable to:
Catwalks, platforms and stair treads
Stair and balcony railing mesh
And far more
