What we need to Know about Perforated Aluminium

Found in the clay mineral bauxite, aluminium is a relatively new discovery in human history. It was produced for the first time in 1824 thanks to the invention of electricity which allowed scientists to break down bauxite’s chemical compounds.

Today, aluminium is so commonly used that if it suddenly disappeared, planes, trains, cars, mobile phones, computers and architecture would be greatly diminished or vanish altogether.

Perforated aluminium – sheeting punched with a repeated pattern of holes – also plays many pivotal roles in making our lives safer, more functional and quieter. Its wide variety of applications spans audio and agricultural equipment, interior and exterior design, fencing, filtration and noise control. 

If you’ve seen perforated cladding on walls in your local club, chances are it’s not just there as a decoration but to soften the sound of the room by absorbing the noise. Just as sound can be ‘sucked in’ to a perforated aluminium panel, light can be diffused out of it, in all directions and intensities. It’s also a clever way to create instant privacy to an area.

Perforated Aluminium in Comparison with Other Metals

We believe if there was a ‘poster-boy’ of the perforated non-ferrous metals family, aluminium would be it. 

Lightweight yet very strong, easily machined and non-sparking, perforated aluminium is perfect for both functional and aesthetic applications. Add to this the cost savings on shipping and handling thanks to its strength-to-weight ratio and it’s no wonder it’s so commonly used.

In terms of longevity, aluminium perforated sheet metal is among the most durable and longest lasting of metals. It will stand the test of time, for both indoor and outdoor uses thanks to its high resistance to corrosion. 

Shapes of Perforations

Staggered or in straight rows, hole sizes can vary from round to square, slotted, hexagonal and more. We have a huge variety of patterns to choose from, so please ask!

The effect of perforation shapes for privacy/visibility

The reasons for erecting a perforated aluminium screen can vary from masking an unsightly area, creating a more seamless transition between non-matching buildings to the need for privacy without losing visibility. 

The larger the holes and the more perforations per square foot, the airier and more open it will be with increased visibility.

When privacy is the main consideration, we provide patterns with very small perforations. An example of one privacy design is thousands of tiny downward facing holes punched into a fine flat sheet of aluminium. The result is you can see out without being seen.

The effect of perforation shapes on sounds/acoustics

Manufacturers solve the problem of noisy appliances with perforated aluminium. The super strong aluminium acts like it is ‘transparent’, allowing sound waves to pass through so the sound doesn’t bounce but is absorbed.

With thanks to the scientists of yesteryear, Acorn Metal Solutions are proud to have taken up the baton in the 21st Century, engineering and manufacturing premium perforated aluminium. We understand the need for precision, strength and high quality finishing. That’s where our state-of-the-art machinery comes into its own, delivering cost-effective aluminium perforation quickly and efficiently.
