What is Expanded Metal?
Expanded metal is a sheet of metal fabricated with an everyday pattern of diamond-formed openings. These openings reduce the load and value of the sheet and provide air flow, making it a flexible solution for a lot of applications. The commonest metals used for expanded metal sheet embrace 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 cutting machine. The knives move back and forth in a uniform sample, slicing the sheet in alternating cuts, while the sheet moves through the machine.
Because the knives reduce, they concurrently push down on the newly reduce sections, stretching them apart into "ribbons." The ribbons stay attached at the uncut sections, which grow to be 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 changed to create openings of different dimensions for quite a lot of applications.
Types of Expanded Metal
Expanded metal sheet comes in completely different profiles, including:
Customary Expanded Sheet: A completed product as it comes off the press after being cut and expanded. Typically referred to as raised expanded metal, as a result of alternating ridges formed 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 standard 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. Ultimate for catwalk and platform applications.
A Versatile Product
Expanded sheet metal is a flexible and economical product that's durable, easy to work with, and provides low wind resistance. It gives one-piece construction that won’t unravel under regular circumstances, and will 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, such as:
Catwalks, platforms and stair treads
Stair and balcony railing mesh
And much more
