What is Expanded Metal?
Expanded metal is a sheet of metal fabricated with a regular pattern of diamond-formed openings. These openings reduce the load and price of the sheet and provide ventilation, making it a versatile answer for a lot of applications. The most common metals used for expanded metal sheet embody steel, stainless metal, and aluminum, though 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 cutting machine. The knives move back and forth in a uniform sample, slicing the sheet in alternating cuts, while the sheet moves by means of the machine.
As the knives minimize, they concurrently push down on the newly minimize 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 scale, shape and positioning of the knives and the thickness of the metal sheet might be changed to create openings of different dimensions for a wide range of applications.
Types of Expanded Metal
Expanded metal sheet is available in different profiles, including:
Customary Expanded Sheet: A finished product as it comes off the press after being cut and expanded. Often referred to as raised expanded metal, because of the alternating ridges shaped by overlapping metal strips.
Flattened Expanded Sheet: A normal expanded sheet that's 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 steel sheet or plate. Expanded metal grating has no joints or welds, as every sheet is a single piece of sturdy steel. Preferrred for catwalk and platform applications.
A Versatile Product
Expanded sheet metal is a versatile and economical product that's durable, simple to work with, and provides low wind resistance. It affords 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 used in a wide range of applications, resembling:
Catwalks, platforms and stair treads
Stair and balcony railing mesh
And much more
