What's Expanded Metal?
Expanded metal is a sheet of metal fabricated with an everyday sample of diamond-formed openings. These openings reduce the weight and price of the sheet and provide air flow, making it a versatile solution for a lot of applications. The most typical metals used for expanded metal sheet embrace steel, stainless metal, and aluminum, although it can also 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 pattern, slicing the sheet in alternating cuts, while the sheet moves by way of the machine.
Because the knives reduce, they concurrently push down on the newly minimize sections, stretching them apart into "ribbons." The ribbons remain attached at the uncut sections, which turn into the corners of open diamond shapes in an expanded mesh sheet. The scale, form and positioning of the knives and the thickness of the metal sheet may be changed to create openings of different dimensions for a variety of applications.
Types of Expanded Metal
Expanded metal sheet comes in completely different profiles, including:
Standard Expanded Sheet: A finished product as it comes off the press after being cut and expanded. Often referred to as raised expanded metal, as a result of alternating ridges shaped by overlapping metal strips.
Flattened Expanded Sheet: An ordinary expanded sheet that is then cold rolled, leaving a flat, smooth surface. Flattened expanded sheet is about 5% lighter than standard 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. Ideally suited for catwalk and platform applications.
A Versatile Product
Expanded sheet metal is a flexible and economical product that is durable, easy to work with, and provides low wind resistance. It provides one-piece building that won’t unravel under normal circumstances, and will hold its form for many years. The strands and bonds of the diamond-shaped trusses add power and rigidity.
It is commonly used in a wide range of applications, reminiscent of:
Catwalks, platforms and stair treads
Stair and balcony railing mesh
And far more
