In the construction industry, aluminum has been favored for building windows and doors due to its lightweight yet durable nature. Better, aluminum can be processed with different techniques to achieve diverse appearances. These different types of aluminum finishes not only enhance the aesthetic appeal but also provide varying degrees of durability and functionality.
HOMI, as an experienced aluminum product manufacturer, will introduce 7 types of aluminum finishes commonly used in the industry, guiding you through their unique characteristics and considerations for choosing the right finish for your needs.
Types of Aluminum Finishes
1. Anodized Aluminum
Anodizing thickens the protective oxide layer on aluminum. This electrochemical process enables different coating thicknesses to protect the underlying aluminum from external elements. This way, it allows for better corrosion and wear resistance. Moreover, it helps increase the metal’s ability to accept dyes, offering more aesthetic possibilities.
2. Electrophoresis Aluminum
Electrophoresis aluminum refers to aluminum that has undergone an electrophoretic coating process. This process involves placing oxidized aluminum in a water-soluble emulsion and passing direct current electricity through it.
As a result, a protective layer of paint film is deposited on the surface of the aluminum oxide film. The electrophoresis aluminum surface typically has advantages, including high hardness, good adhesion, a uniform appearance, and great corrosion resistance.
3. Powder Coated Aluminum
Powder coating involves applying dry paint powder onto the aluminum surface. Then, after being cured under heat, the aluminum parts will have an even finish that features long-lasting colors resistant to UV rays. Powder coatings, though less hard and durable than anodized aluminum, do an exceptional job regarding appearance and corrosion resistance as long as the coating remains intact.
4. PVDF Coated Aluminum
PVDF (Polyvinylidene Fluoride) coatings are a resin-based coating system. The coating process often involves a primer layer, a color coat, and sometimes a clear topcoat for added protection. This treatment technique makes the aluminum part resistant to sunlight, corrosion, wear, and abrasion and provides it with high color stability. However, it should be noted that PVDF coating can only create matte finishes.
5. Sublimated Aluminum
Traditionally used in the textile industry, the sublimation process transfers patterns and images to the aluminum surface. Different from printing, the sublimation dyes penetrate the surface to have long-lasting effects. There can be many design options, like wood (a popular choice), concrete, rust, and more, to achieve artistic effects.
6. Brushed Aluminum
Brushed aluminum is an aluminum surface finish that looks luxurious while requiring affordable manufacturing costs. It creates a distinctive textured appearance by brushing the aluminum surface with abrasive tools. This unique finish helps disguise scratches and fingerprints while offering many benefits like high corrosion resistance, low maintenance, and sleek aesthetic appeal.
7. Painted Aluminum
Painted aluminum uses organic coatings that boast endless color possibilities. Plus, the paint forms a protective barrier against environmental factors like moisture, UV rays, and corrosive substances. Though it may chip or flake (after a long time), painted aluminum surfaces are popular due to their greater design flexibility.
Considerations When Choosing Aluminum Surface Finishes
With different types of aluminum finishes available, you can make your final choice by considering the following factors:
1. Indoor or Outdoor Use
The first consideration is whether the aluminum will be used indoors or outdoors. Different aluminum finish types have varying degrees of resistance to environmental factors like UV rays and moisture.
For instance, anodized aluminum features high corrosion and wear resistance, making it suitable for outdoor applications, while painted aluminum might be more appropriate for indoor use where exposure to the elements is minimal.
2. Aesthetic Match
The appearance of the aluminum finish should complement the building’s design and style. Sublimated aluminum with wood-like finishes can provide a natural and elegant look, while brushed aluminum offers a sleek and modern appearance. The choice of finish should enhance the visual appeal and align with the desired aesthetic goals.
3. Cost Implications
The budget limit also impacts decision-making. Different finishes have varying prices based on the materials and processes involved. For example, powder-coated aluminum is often more cost-effective compared to PVDF-coated aluminum, which is known for its superior durability but comes at a higher price.
4. Durability and Maintenance
Finally, durability and maintenance requirements are crucial. Some finishes, like electrophoresis aluminum, offer excellent long-term durability with minimal maintenance, making them ideal for applications where low upkeep is a priority. At the same time, painted aluminum may require more frequent repainting or touch-ups over time.
By assessing the above 4 critical factors carefully, you can make a sound decision that aligns with the project’s long-term goals and resources.
