Перфорированного металла

Perforated Metal Material:Mild Steel, Stainless steel, Galvanized, Aluminum, Brass, Copper. Specification:We can manufacture a wide rang of thick sheet verifying from 0.1mm to 10mm. Length is the overall measurement of the long side of the sheet. Width is the overall measurement of the -short side of the sheet. The standard sheet size is width 0.9 meter, 1.0 meter, 1.25 meter and 1.5 meter. The coil width of 1.22 meter is also available. We also can process the special product for your requirement by your exact specification. The hole shape: Round, square, long round, triangle, scale, diamond, oval, hexangular, slot etc. Aperture: In general it is advisable to use a hole size larger than the material thickness. The closer the hole size and material thickness come to a 1 to 1 ratio, the more difficult and expensive the process is. Dependent on the material type, smaller hole size to material ratios can be achieved. Pitch: Hole center is the distance from the center of one hole to the center of the nearest hole in the next adjoining row. Open area: Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent, Keep in mind that punching holes in a material add stresses that can result in distortion of the product. The higher the open area, the more material distortion takes place, especially when the perforated pattern is bordered by margins on all four sides. But these distortions can be removed by our special in house leveling process. Special specifications can be produced by the customer's requirements.
