Using Perforated Sheet Metal For Ventilation

What is a perforated sheet?

Perforated metal is a sheet metal form that has been punched or stamped by using a machine to create holes in it. Perforated sheets are also known as perforated plates or perforated screens. These are commonly made by using aluminium, stainless steel, and cold-rolled steel. One can identify the perforated metal sheet by its opening size, width, the pattern of the holes on it, and the characteristics of the perforated sheet.

It is mainly used to control the different passages of air light and liquids through an enclosure. It even can control the passages of sound as well.

Why is enclosure ventilation a must?

So, why do you need ventilation in an enclosure? The enclosure that has electronics inside it will generally generate an amount of heat. If the heat stays within that enclosure, it can be risky. That’s why you need to use proper ventilation so that the heat can go out. For this cause, you can custom cutouts to the enclosure. If you do that, you can control the number of cutouts and the shapes and positions as well. But does it worth your time, investment, and effort? You’ll need to add hundreds of cutout holes for ventilation purposes, and even after that, it may not give you the satisfying result you are looking for.

Perforated sheet and ventilation 

It is better to use perforated sheet metal as it will not only save your energy and time but also require less investment. It has hundreds of tiny holes inbuilt. On the other hand, if you laser cut these tiny holes, it would be too much expensive.

Perforated sheet is a way cost-effective option compared to others. No matter whether the sheet is made of Aluminum or cold-rolled steel, it would be effective for ventilation. You can attach the sheet to an enclosure by using welding techniques or fasteners.


Thinking about customizing your performed sheet? You can easily do it by adding a finishing. If you are using aluminium performed material, you can use it without any finish or add a grained finish with it. You can also anodize it powder coat it by using a stock colour.

If you don’t love the idea of welding, it is better to use stainless steel fasteners as they will provide you with the material compatibility you need for perfect ventilation.

Talking about cold-rolled steel perforated material, you should not leave it without any finishing as it will rust with time. You can powder coat it. If you don’t love the idea of welding, you can use zinc-plated fasteners to mount your perforated sheet with the enclosure.
