What is Expanded Metal?
Expanded metal is a sheet of metal fabricated with an everyday pattern of diamond-shaped openings. These openings reduce the weight and value of the sheet and provide ventilation, making it a flexible solution for a lot of applications. The commonest metals used for expanded metal sheet embrace metal, 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 reducing machine. The knives move back and forth in a uniform sample, slicing the sheet in alternating cuts, while the sheet moves by the machine.
Because the knives cut, they simultaneously push down on the newly reduce sections, stretching them apart into "ribbons." The ribbons remain connected at 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 different dimensions for a variety of applications.
Types of Expanded Metal
Expanded metal sheet is available in completely different profiles, including:
Customary Expanded Sheet: A completed product as it comes off the press after being minimize 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 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. Ultimate for catwalk and platform applications.
A Versatile Product
Expanded sheet metal is a flexible and economical product that's durable, straightforward to work with, and provides low wind resistance. It affords one-piece development that won’t unravel under regular circumstances, and can hold its form for a lot of years. The strands and bonds of the diamond-shaped trusses add energy and inflexibleity.
It's commonly utilized in a wide range of applications, reminiscent of:
Catwalks, platforms and stair treads
Stair and balcony railing mesh
