Perforated metal specification
1. Plate selection
When select the plate, make sure that take both application requirement and product cost into consideration.
If you’d like to reduce the thickness of plate, you’d better use the alloy materials with slightly higher price.
At the same time the hardness and strength of plate directly determines the sizes and arrangement of holes.
We can supply the plate materials as follows: Stainless Steel plate, High or Low carbon Steel Plate,
Galvanized Plate, Zinc Plate, Aluminum Plate, Aluminum Alloy Plate, Mg-Al Plate and Nickel Plate ,etc.
In general it is advisable to use a hole size larger than the material thickness. That is, to meet the minimum
aperture principle. The closer the hole size and material thickness,
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.
If you have the special need,we wil try best to meet your need with the most reasonable price and the most
3. Hole spacing
Hole center is the distance from the center of one hole to the center of the nearest hole
in the next adjoining row.
Hole spacing is a way to indicate hole center, another way is opening area.
Both the significance of two methods is the same. You only need to determine either of both.
4 .Plate specification
The thin plate is easier to perforate and the price is relatively low. According to the principle of minimum
the suitable thickness is more conductive to increasing the compressive strength. In general,
the plate has the tolerance,
we can manufacture a wide rang of thick sheet verifying from 0.1mm to 2.5 mm thickness Sheet width
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. The coil width 1000mm is also available.
We also can process the special product for your requirement if you tell us the exact specification.
5. Opening area
Clearly, 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.
Therefore, the flatness request of products wlill be sent after you take careful consideration in it.
Margins are the blank area along the edges of the sheet. In general, the long sides of plate need the margins,
and the short sides not. 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.
There are tolerances on thickness, pitch, openings, flatness, and shearing for perforated products.
It is the same as other production process, The higher the request about tolerance,
the price of the products will be higher relatively.
You should specify a specific tolerance, so we can give you a precise product.
If not, we will according to standard tolerance.
