Specification of Iron Steel Mesh Expanded Mesh
Expanded Metal is sheet metal made with a regular pattern of diamond-shaped openings. These openings reduce the weight of the sheet and can act as ventilation, making it a versatile solution for many specific applications. The most common metals used for expanded metal include steel, stainless and aluminum, although some are made of titanium and copper.
Expanded Metal is formed from a single sheet of metal that has been cut by a row of blades mounted on industrial cutting machines. The blades move back and forth in a uniform pattern, slicing the sheets in alternating pieces, while the sheets move through the machine.
As the blades cut, they simultaneously press the newly cut portion and stretch it into a "ribbon". The tape remains attached to the uncut, which becomes the corners of the open diamond shape on the expanded mesh sheet. The size, shape and position of the blade as well as the thickness of the sheet metal can be changed to create openings of different dimensions for various applications.
