  • Powder Coated: This finish is applied as a dry powder and then cured under heat to form a hard coating. Powder coating provides excellent durability and color options.
  • Brushed: This finish creates a textured surface that is both visually appealing and hides scratches and fingerprints.
  • Polished: This finish creates a mirror-like surface that reflects light and provides a high-end look.

Color Options

Extruded aluminum panels can be finished in a wide range of colors, making them an excellent choice for achieving specific design aesthetics. The color options include:

  • Standard Colors: These are the most commonly used colors and are readily available. They include white, black, gray, and bronze.
  • Custom Colors: These colors are available upon request and can be matched to any color sample provided by the client.
  • Metallic Colors: These colors contain metallic flakes that create a unique and eye-catching appearance.
  • Wood Grain Finishes: These finishes mimic the look of wood and are perfect for achieving a natural appearance.

Overall, extruded aluminum panels provide a versatile and customizable solution for achieving unique design aesthetics. With a variety of surface finishes and color options available, architects and designers can create stunning and functional facades that meet their clients’ specific needs.

Manufacturing Process

Extrusion Techniques

Extruded aluminum panels are made using a process called extrusion. This process involves heating a cylindrical billet of aluminum to a temperature of around 500°C and forcing it through a die using a hydraulic press. The die determines the shape and size of the extruded panel. Extrusion is a cost-effective method of producing aluminum panels, as it allows for the creation of complex shapes and designs with minimal waste.

There are two main types of extrusion techniques used in the production of aluminum panels: hot extrusion and cold extrusion. Hot extrusion involves heating the aluminum billet to a high temperature before extruding it, while cold extrusion involves extruding the aluminum at room temperature. Hot extrusion is typically used for larger panels, while cold extrusion is used for smaller, more intricate designs.

Cutting and Assembly

Once the aluminum panel has been extruded, it is cut to size using a saw or other cutting tool. The panel is then assembled using various techniques, depending on the design and intended use of the panel. For example, panels used in construction may be assembled using screws or bolts, while panels used in electronics may be assembled using adhesives or other bonding agents.

In addition to cutting and assembly, the aluminum panel may also undergo various finishing processes, such as painting or anodizing. These processes can help to improve the appearance and durability of the panel, as well as provide additional protection against corrosion and other forms of damage.

Overall, the manufacturing process for extruded aluminum panels is a complex and precise operation that requires skilled technicians and specialized equipment. However, with the right techniques and processes in place, it is possible to produce high-quality panels that meet the needs of a wide range of industries and applications.


Extruded aluminum panels have a wide range of applications in various industries. Here are some of the most common applications:

  • Electronics: Extruded aluminum panels are used in the electronics industry for various applications, such as enclosures, heat sinks, and frames. They offer excellent thermal management, electromagnetic shielding, and corrosion resistance.

Overall, extruded aluminum panels offer a wide range of applications across different industries due to their unique properties and versatility.

Installation and Mounting

Fixing Methods

Extruded aluminum panels are lightweight and easy to install, making them an ideal choice for a variety of applications. There are several fixing methods that can be used to mount these panels, including:

  • Screw fixing: This method involves drilling holes in the panel and then screwing it onto the substrate using self-tapping screws. This method is suitable for both vertical and horizontal installations.
  • Adhesive fixing: Adhesive fixing involves using a high-strength adhesive to bond the panel to the substrate. This method is ideal for curved surfaces or where screw fixing is not possible.
  • Clip fixing: Clip fixing involves using a special clip system to hold the panel in place. This method is ideal for areas where the panel needs to be easily removable.

When fixing extruded aluminum panels, it is important to ensure that the substrate is clean, dry and free from any contaminants that may affect the adhesion of the panel. It is also important to follow the manufacturer’s instructions for the specific fixing method being used.

Safety Considerations

When installing and mounting extruded aluminum panels, it is important to take proper safety precautions. This includes wearing appropriate personal protective equipment, such as gloves and safety glasses, and using the correct tools for the job.

It is also important to ensure that the panels are installed in accordance with local building codes and regulations. This may include using fire-resistant materials or ensuring that the panels are properly grounded.

In addition, care should be taken when handling and transporting the panels to avoid damage and injury. Panels should be stored in a dry, secure area and handled with care to prevent any dents or scratches that may affect the final appearance of the installation.

By following these simple guidelines, extruded aluminum panels can be safely and easily installed for a variety of applications.

Maintenance and Durability

Extruded aluminum panels are known for their durability and low maintenance requirements. The panels are resistant to corrosion, fading, and other environmental factors, making them an excellent choice for both indoor and outdoor applications.

To maintain the appearance of extruded aluminum panels, regular cleaning is recommended. A simple cleaning solution of mild soap and water can be used to remove dirt and grime. For tougher stains, a non-abrasive cleaner can be used. It is important to avoid using harsh chemicals or abrasive materials, as they can damage the finish of the panels.
