What's Expanded Metal?

What's Expanded Metal?

Expanded metal is a sheet of metal fabricated with an everyday pattern of diamond-formed openings. These openings reduce the burden and value of the sheet and provide ventilation, making it a versatile solution for a lot of applications. The most typical metals used for expanded metal sheet embrace steel, stainless steel, and aluminum, though 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 sample, slicing the sheet in alternating cuts, while the sheet moves through the machine.


As the knives minimize, they concurrently push down on the newly minimize sections, stretching them apart into "ribbons." The ribbons remain attached on the uncut sections, which develop 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 could be changed to create openings of different dimensions for a variety of applications.

Types of Expanded Metal

Expanded metal sheet is available in completely different profiles, including:

Commonplace Expanded Sheet: A finished product as it comes off the press after being minimize and expanded. Usually referred to as raised expanded metal, as a result of alternating ridges fashioned by overlapping metal strips.

Flattened Expanded Sheet: A regular expanded sheet that is 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. Superb for catwalk and platform applications.

A Versatile Product
Expanded sheet metal is a flexible and economical product that's durable, simple to work with, and provides low wind resistance. It affords one-piece development that won’t unravel under normal circumstances, and can hold its form for many years. The strands and bonds of the diamond-formed trusses add energy and inflexibleity.

It is commonly used in a wide range of applications, such as:


Machine guards

Catwalks, platforms and stair treads

Grating/flooring

Stair and balcony railing mesh

Window security

Vents

Conveyers

Cabinets

And much more
