What is expanded metal? Expanded metal mesh sheet is fabricated with a regular pattern of diamond-shaped openings. These openings reduce the weight and cost of the sheet and provide ventilation, making it a versatile solution for many applications. The most common metals used for expanded metal sheet include steel, stainless steel, and aluminum, although it is also made from titanium and copper.

How are expanded metal sheets made? Expanded sheet is made from a single sheet of metal slit by a row of knives mounted on an industrial die-cutting machine. The blades move back and forth in a uniform pattern, slicing the sheet in alternating cuts while the sheet moves through the machine. As the knives cut, they simultaneously push down on the newly cut sections, stretching them apart into “strands.” The strands remain attached to the uncut sections, which become the corners of open diamond shapes in an expanded mesh sheet. The knives' size, shape, positioning, and thickness of the metal sheet can be changed to create openings of different dimensions for various applications.

How to measure the mesh of expanded metal? The record is made up as follows: Mesh width (LW) x mesh height (SW) x strand width (w) x material thickness (t).

Position of expanded metal eye against the sheet? The mesh width will always be parallel to the sheet width. The standard sheet widths are mostly 1000 / 1250 / 1500 mm. However, depending on the mesh size, they can also be max 1000mm, or even up to 2400mm wide.. True, at a width of 2400mm, there will be a limited height ( sw), because the production will already take place from a sheet, not a coil, which has an unlimited length.

Where can I buy expanded sheets? Expanded metal sheets can be ordered by calling or writing to the VRV Metals team. www.vrvmetals.lv

How to order expanded sheets correctly? Important to specify the following information: Material type - Black, galvanized, Aluminum, stainless steel. Etc. Material thickness ( mm ) Mesh width x length x strand width ( mm) Sheet size ( mm) Volume, number of sheets ( pcs) Example: AL 1050 , 3 mm 50x20x10 mm 1155x2200 mm 200 pcs

What is the difference between flattened and non-flattened mesh? After production, the mesh is unflattened.. The benefits of unflattened mesh - it is multi-layered with different transparency at different angles. In the unflattened form, the mesh is also much stiffer/more alive.. The greater the strand width ( w), the stiffer the mesh will be, less transparent. When flattened, the mesh remains in 2 dimensions, its total thickness is almost the same as the thickness of the material and all the strength already lies on the thickness of the material. Flattened mesh is more often used in filtration, screening equipment, and often as design elements.
