Perforated Metal Patterns Views
There are countless numbers of perforating patterns possible with many types of hole, including round, square, hexagonal, rectangular, triangular and oblong. The most common patterns used in conventional perforated sheet metal are straight line and staggered patterns. In a straight line pattern, the hole arrangement can be determined by two parameters: Vertical and horizontal direction. To create a square pattern, both directions should have equal distances. If the distance in the vertical direction is not the same as in the horizontal direction, the perforated pattern will be called a rectangular pattern. Unfortunately, compared to a staggered pattern, this straight line pattern is not as strong as the staggered pattern due to the nature of the layout.
Besides all those uniform and conventional perforated metal patterns a new perforated pattern based on an image has also become available widely. This opens a new and exciting market opportunity for any perforated sheet metal project which can benefit both the supplier and the customer. Basically, the perforated pattern is generated by capturing the image's colour by using a specific calculation / algorithm, and then all information is translated in a sophisticated way to create a pleasant perforated pattern design which reflects the original image in some way.
As shown in Chart 1, the tests proved that there was virtually no diminishment of the fiberglass's sound absorption performance by the presence of any of the perforated metal patterns. Each of the perforated-protected tests followed very closely the performance of the bare fiberglass at all frequency levels.
For staggered pattern perforated metal punctures, the end patterns come in either finished or unfinished cuts. This perforated metal pattern depends on the time and specific tooling available. The unfurnished end pattern is standard on all perforated sheets however the finished end is available upon request.
