What is the aluminum extrusion woodgrain process?
Aluminum wood grain finish is a surface treatment that gives aluminum alloy profiles the look of wood. This process creates a wood-like appearance while maintaining the advantages of metal. Below is a clear explanation of how the wood grain aluminum surface treatment works.
Wood Grain Aluminum Extrusion Process
Principle of Treatment
The aluminum woodgrain finish uses high-temperature heat to transfer a wood grain texture onto aluminum profiles. This process follows the application of powder coating or electrophoretic painting. By applying heat and pressure, the wood grain pattern from transfer paper or film penetrates the coated aluminum profiles.

Common Colors
Wood grain aluminum is available in several colors, including:
- Ash
- Yellow sandalwood
- Golden oak
- Silver silk white wood
- Teak
- Antique wood color
These colors mimic natural wood, providing an appealing finish while maintaining the durability of aluminum.
Advantages of the Wood Grain Process
- Anti-Aging and Fading – The woodgrain finish resists aging and fading. It keeps a bright wood grain effect for a long time, maintaining an attractive appearance.
- Strong Corrosion and Weather Resistance – This finish offers strong corrosion resistance. It performs well in harsh climates and coastal areas, withstanding unfavorable weather conditions.
- Good Three-Dimensional Effect – Woodgrain aluminum features a clear and natural woodgrain texture. Its three-dimensional effect is impressive, making it a great alternative to traditional wood.
These advantages make the aluminum extrusion woodgrain process an excellent choice for those who want durability and aesthetic appeal.
Wood Grain Processing Flow
The wood grain aluminum treatment process includes several key steps:
- Substrate Spraying or Electrophoresis – First, apply powder coating or electrophoretic painting to the aluminum profiles. This step creates a solid foundation for the wood grain transfer.
- Film Application – Next, place transfer paper or film with a wood grain pattern onto the aluminum profiles after spraying or electrophoresis.
- Baking – Bake the aluminum profile in an oven at 190-200°C. The heat causes the ink on the transfer paper to sublimate and transfer onto the aluminum coating.
- De-Filming – After baking, carefully remove the transfer paper or film from the aluminum profile.
- Packing – Finally, pack the wood grain aluminum for transportation and storage.
This process transforms standard aluminum profiles into attractive wood grain finishes, combining the beauty of wood with the strength of aluminum.
