What is Expanded Metal?
Expanded metal is a sheet of metal fabricated with a daily pattern of diamond-formed openings. These openings reduce the load and price of the sheet and provide air flow, making it a versatile answer for a lot of applications. The commonest metals used for expanded metal sheet embrace metal, 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 slicing machine. The knives move back and forth in a uniform pattern, slicing the sheet in alternating cuts, while the sheet moves by means of the machine.
Because the knives minimize, they concurrently push down on the newly cut sections, stretching them apart into "ribbons." The ribbons stay attached on the uncut sections, which turn out to be 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 quite a lot of applications.
Types of Expanded Metal
Expanded metal sheet comes in different profiles, including:
Commonplace 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 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 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 every sheet is a single piece of sturdy steel. Excellent 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 gives one-piece construction that won’t unravel under regular circumstances, and will hold its shape for a lot of years. The strands and bonds of the diamond-shaped trusses add energy and inflexibleity.
It is commonly utilized in a wide range of applications, equivalent to:
Catwalks, platforms and stair treads
Stair and balcony railing mesh
