What Is Expanded Metal?

Expanded metal is a sheet of metal fabricated with a daily sample of diamond-formed openings. These openings reduce the load and value of the sheet and provide air flow, making it a versatile resolution 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 chopping 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 minimize, they concurrently push down on the newly minimize sections, stretching them apart into "ribbons." The ribbons remain hooked up on the uncut sections, which grow to be the corners of open diamond shapes in an expanded mesh sheet. The size, shape and positioning of the knives and the thickness of the metal sheet will 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, together with:

Customary Expanded Sheet: A finished product as it comes off the press after being minimize and expanded. Often referred to as raised expanded metal, because of the alternating ridges formed by overlapping metal strips.

Flattened Expanded Sheet: A typical 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. Preferrred 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 construction that won’t unravel under regular circumstances, and will hold its form for a lot of years. The strands and bonds of the diamond-shaped trusses add energy and inflexibleity.

It's commonly used in a wide range of applications, similar to:

Machine guards

Catwalks, platforms and stair treads


Stair and balcony railing mesh

Window security
