Materials that are perforated are very much versatile. Perforated metal offers very distinct opportunities to combine functionality, beauty and strength. This certain type of metal can have lightweight decorative elements and at the same time load bearing components.
You can use perforated metal in achieving your design objectives. Perforated sunscreens and sunshades are part of elaborate designs of internal designers in order to provide privacy for house occupants without even blocking the amazing view from your window. The perforated sunscreens and sunshades offer an enough amount of natural lighting to stream inside your room during daytime and at the same time it deflects the heat in order to reduce the pressure on the HVAC system. Other perforated materials like the perforated cladding, canopies and façade are commonly used to control the feel and climate inside the building or house and at the same time save energy.
The use of perforated metal and materials is limited in that it lacks reliable strength and the proper amount of stiffness to be effectively used in designs. Materials with round holes in the standard of 60 degrees triangular pattern accounts for approximately more than half of the production of the perforating industry. This pattern is commonly used and is very versatile in application. The most popular round-hole arrangement is the 60 degrees pattern since it has inherent strength and provides a wide range of open areas at the same time.
Metal workers conducted several tests comparing at least 26 non-perforated and perforated metal samples which range from .20 to .75. The study proved that materials that were perforated have unique strength and stiffness which depends largely on the direction of loading the materials. The round-hole pattern among perforated materials accounted for at least more than half of the production in the perforating industry that is why tests were performed on this type of perforation. Designers and different skilled workers can use the result of the test in order to provide information as to the thickness of perforated material that will provide the stiffness and the strength equal to materials that are not perforated.
Tests that were performed on different perforated metals that had thin gauge measured the amount of pressure loss at various angles and velocities. The sample products were placed inside perpendicular, uniform and non swirling air flow streams.
For acoustical, there are in essence two principal application of perforated metal. One is as a decorative material and another as part of a resonant absorber. When the perforated material is used as a decorative material, it has to be transparent so that the sound waves may easily pass through it without being reflected or diminished. The objective of a lot of acoustical applications is to reduce the sounds that occur in a very narrow range of frequency.
