Specification
we can manufacture a wide rang of metal sheets with thickness verifying from 0.35mm to 3 mm and width maximum 1200mm. 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 1000mm*2000mm. and 1000mm*2500mm. The coil width 1000mm is also available. We also can process the special product for your requirement.
The hole shape
Round, square, long round, triangle, scale, diamond, oval, hexangular, slot etc.
Sheet Metal 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. The minimum diameter we can fabricate is 0.8mm to 4 mm thickness. If you require a die that isn't already in our die bank, our experienced tool and die makers can quickly make exactly what you need at a reasonable cost.

Pattern
we offer perforated sheets with more options and less cost. Equipped with computerized-programmable feed systems, we will expand your custom design options.
Our Perforated Sheet is available in the following patterns:
Round, square, oblong, triangle, slot, hex, oval, diamond and a broad variety of special shaped holes. We have tooling available for many different hole patterns and shapes. It is more economical to choose one of the available patterns, although special hole sizes and patterns can be accommodated at additional cost.
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.
Margins
Margins are the blank area along the edges of the sheet. If you want the product with special margins, you should provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole).Manufacturing considerations may affect margins. If the margins requested are not possible. We will replace it with the similar products as your consideration.
Tolerances
There are tolerances on thickness, pitch, openings, flatness, and shearing for perforated products. You should specify a specific tolerance, so we can give you a precise product. If not, we will accord standard tolerance.

Perforated metal sheet is used for oil filters, as fencing screen for expressway, railway and other construction facilities, used in workshops as well as other constructions as sound isolation sheet, decorative sheet for stairs, environmental tables and chairs, sifting in grains, feed and mines. Perforated metal screen sheet is also used in making of kitchenware such as fruit basket, food cover, etc.
