Perforated aluminum sheets are aluminum sheets made by mechanical pressure processing, which feature evenly spaced holes formed into the aluminum sheet. Perforated aluminum mesh is highly resistant to corrosion, is a relatively light metal compared to metals such as steel, nickel, brass, and copper, and is fairly ductile. Aluminum sheets with holes can have a variety of surface finishes and are highly reflective of heat and light. For most applications, perforated aluminum plate does not require a protective coating, but is often anodized to improve color and strength.

Punched aluminum sheets are very useful at low temperatures. At sub-zero temperatures, their strength increases while maintaining ductility. Aluminum sheet tends to lose some of its strength at temperatures above 400F.

What is Aluminum Perforated Metal?

Perforated aluminum sheet metal is a sheet of metal that has been punched or embossed with a pattern of holes or other shapes. The perforations come in a variety of shapes and sizes, depending on the functionality and aesthetics required. Aluminum perforated metal is often used in architectural applications, such as building exteriors, and industrial applications, such as ventilation systems, acoustic panels, and filtration. It is valued for its lightweight, corrosion-resistant properties, and ability to be formed into a variety of shapes and sizes.

Material properties

1. Material: Aluminum perforated metal sheet is usually made of pure aluminum or aluminum alloy.

2. Shape and color: Aluminum sheet with holes has a beautiful shape, elegant color, and good decorative effect.

3. Performance: It has good corrosion, weather, and wear resistance.

Mechanical Properties

a). 3003 is the most popular aluminum alloy and is often used as a general purpose alloy. Softer than 5052 grade aluminum, it has good formability, weldability, and strength, and is often used in filters, fuel tanks, and general sheet metal processing. 3003 is usually the default specification.

b). 5052 grade aluminum is more corrosion resistant than 3003 grade, suitable for use in saltwater environments. In the construction field, 5052 is by far the most widely used alloy because it is very suitable for anodizing! It is also harder, stronger, and more wear-resistant, and is often used in storage tanks, pressure vessels, and marine applications.

Of course, other alloys you can also purchase include 1100, 2024, 6061, 6063, and 7075.

Non-Heat-Treatable Alloys
1100–0 H14	Pure aluminum (content at least 0.99%) is highly resistant to attack by chemicals and by rural, industrial, and marine atmospheres. It is easily machined and ductile enough for deep drawing. It is generally used in applications where the basic qualities of aluminum are beneficial.
3003–0 H14	The most widely used general purpose alloy. Stronger than 1100, yet still easily formable. Very good chemical and weather resistance. Recommended for general use where extra strength is required.
5050–H34	Physical properties and corrosion resistance are very similar to 3003, but slightly lighter. Recommended for anodizing applications to best match extruded aluminum parts.
5052–0 H32 / H34	A versatile alloy is suitable for applications where higher strength is required. Easily formable with excellent corrosion resistance. Recommended for applications where high strength and formability are required.
5066–H32 / H34	Recommended for welding assemblies requiring both welding efficiency and high joint strength. Good corrosion resistance. Typical applications include pressure vessels, ship superstructures, and transportation equipment.

Which shape is the most popular?

The most common aluminum perforated metal sheet mesh shape is a round hole pattern. Because round holes provide a good balance between open area and strength, round-hole aluminum perforated screen can be used for filtration, ventilation, decorative purposes, etc. Other common hole shapes include square, rectangular, and slotted patterns. The choice of shape depends on the specific application and the desired aesthetic appearance.

Our best-selling option has a 3 mm round hole.

Features and benefits of perforated metal sheets

Perforated sheet, also named perforated metal sheets, is made through metal punching processes for high filterability with superior weight reduction. It has various advantages ranging from noised reduction to heat dissipation and other various benefits for different applications.

What is its production process?

Aluminium perforated is produced by a punching or perforation process. The process includes the following steps:

1. Raw material preparation

Aluminium sheets are prepared according to the required size and thickness.

2. Punching and forming

The required hole pattern is created in the aluminium sheet using a punching machine, and then the aluminium sheet is bent or sheared into the required shape.

3. Surface treatment

The perforated metal aluminium sheet can be subjected to surface treatments such as anodizing, powder coating, or painting to enhance its aesthetics and corrosion resistance.

The punching process can be carried out using a variety of techniques, including mechanical punching, laser cutting, and water jet cutting.

Application Areas

Decorative perforated aluminum sheet complements any structure, adding a visually stunning element to both indoors and outdoors. It is a popular choice that is both practical and beautiful, and the uses of aluminum perforated are almost endless. Aluminum becomes stronger when the temperature drops below freezing.

It can even withstand prolonged contact with certain chemicals commonly found in outdoor environments, making it an excellent choice for architectural applications that require durability without sacrificing beauty or structural integrity.

1. Architectural decoration: Decoration of public buildings such as hotels, restaurants, theaters, and broadcasting studios, and medium- and high-end civil buildings to improve sound quality.

2. Noise reduction measures: In various workshops, factories, and air defense basements, aluminum hole sheets can be used as noise reduction measures to effectively reduce the spread of noise.

3. Shading and anti-glare: Sunshades control light while blocking direct sunlight, preventing glare, and making indoor illumination evenly distributed.

4. Filter screens: Stainless steel perforated sheets and perforated aluminum sheets have excellent filtering properties and are used in beehive screens, fish farming screens, grain dryer screens, hammer mill screens, Air diffusers for HVAC equipment, and window machine screens.

How do I calculate the spacing of perforated metal?

How strong is aluminum perforated metal?

There is no fixed number, the actual strength of Perforated aluminum mesh depends on a variety of factors, such as the thickness and pattern of the sheet, the size and shape of the holes, and the material of the aluminum alloy used.

Usually aluminum sheets are lighter than gi perforated sheet, MS perforated sheets, and stainless steel perforated sheets.

And has a good strength-to-weight ratio, making it suitable for a wide range of applications where both strength and weight are important factors.

How to increase the strength of aluminum perforated mesh?

The strength of aluminum perforated metal screen sheet can be further improved by choosing a thicker sheet or a smaller hole pattern, such as reducing the diameter of the individual holes. The design of the screen must take into account the specific application and any load or stress requirements that may exist.

In contrast, a stainless perforated sheet is stronger and may be suitable for your needs.

Can Perforated aluminum sheets be bent?

It is easy to imagine that it is actually a whole sheet of aluminum with some small holes added to the surface, so it is completely possible to bend it.

However, the degree of bending depends on the thickness of the sheet and the hole pattern. Thinner perforated metal sheets with larger holes are easier to bend than thicker sheets with smaller holes.

So the bending process of aluminum sheet metal with holes and perforated aluminum strip is similar to that of solid aluminum sheets. Bending can be done with the help of a bend brake. A bending brake is a tool used to bend the sheet to the desired angle.

Can I spray paint Perforated aluminum sheets?

Yes, Perforated aluminum sheets can be painted. Same painting steps as perforated galvanized sheets. The basic process is as follows:

Clean dirt, and grease → Dry → Choose a paint that is compatible with aluminum and its use → Apply with a spray gun, brush, or roller → Dry → Quality check → Moisture-proof storage → Regular maintenance → Timely repair.

Can Perforated aluminum sheets be welded?

Yes, but it requires certain welding technology.

Aluminum perforated panels are usually made of aluminum alloy, which has a low melting point and high thermal conductivity. So the heat generated during the welding process can easily deform or melt the sheet.

Here, welding technology that can control the heat input and prevent the sheet from deforming is required. A common welding technology for perforated aluminum panels is tungsten inert gas (TIG) welding. TIG welding uses a non-consumable tungsten electrode to generate an arc, melt the aluminum, and form a weld bead. The process can precisely control the heat input and can produce high-quality welds while minimizing deformation.

Perforated aluminium sheet price

The unit price is not fixed. The factors that affect the price are mainly the following three points:

1. Alloy composition

The higher the precious metal content in the aluminum perforated panel, the higher the price is usually.

2. Thickness

The thicker the aluminum plate, the higher the price.

3. Hole pattern

The more complex the holes, the more difficult it is to process, and the price will increase accordingly.
