Comparing Different Types and Finishes of Door Aluminum Profiles

Aluminum has become a popular material for doors due to its durability, versatility, and aesthetic appeal. This article explores the different types and finishes of door aluminum profiles to help readers make informed decisions when selecting doors for their homes or businesses.

Extruded Aluminum Profiles

Extruded aluminum profiles are formed by pushing heated aluminum through a die to create a specific shape. They offer high strength and durability, making them suitable for heavy-duty applications. Extruded profiles can be used for framing, rails, and stiles of doors.

Rolled Aluminum Profiles

Rolled aluminum profiles are created by rolling sheet aluminum into a desired shape. They are thinner and more flexible than extruded profiles, making them ideal for applications where lightweight and flexibility are required. Rolled profiles are often used for door skins, panels, and trim.

Thermal Break Aluminum Profiles

Thermal break aluminum profiles incorporate a layer of insulating material, typically polyurethane, between two layers of aluminum. This construction reduces heat transfer, improving energy efficiency and reducing condensation. Thermal break profiles are best suited for exterior doors in regions with extreme temperatures.

Finishes for Aluminum Profiles

Aluminum profiles can be finished in various ways to enhance their appearance and durability. Some common finishes include:


Anodizing is an electrochemical process that creates a protective oxide layer on the surface of aluminum. It increases corrosion resistance, hardness, and color stability. Anodized profiles come in a range of colors, including clear, bronze, silver, and black.

Powder Coating

Powder coating involves applying a dry powder to the aluminum surface and then baking it to form a durable, weather-resistant coating. Powder-coated profiles offer a wide color palette and excellent resistance to scratches and chemicals.

Woodgrain Laminate

Woodgrain laminate is a vinyl film applied to the aluminum surface to mimic the look of natural wood. It provides the aesthetic appeal of wood without the maintenance and weight. Woodgrain laminates are available in various wood species and finishes.


The choice of door aluminum profile type and finish depends on the specific application and desired aesthetics. Extruded profiles provide strength and durability, while rolled profiles offer flexibility and lightweight. Thermal break profiles enhance energy efficiency. Anodizing, powder coating, and woodgrain laminates provide a range of finishes that enhance appearance and durability. By understanding the different options available, readers can make informed decisions when selecting door aluminum profiles for their projects.
