Aluminum doors are commonly used in homes and businesses today. While they have both advantages and disadvantages, this doesn’t prevent them from becoming one of the most popular metal doors. Below is a detailed introduction to the advantages and disadvantages of aluminum doors.
Advantages of Aluminum Doors
High Hardness:
The door frame of an aluminum door uses aluminum profiles, which are aluminum alloys with added metallic elements such as Mg、Si、Cu, significantly increasing their hardness. Furthermore, the frame of an aluminum door typically features a thermal break design, and the internal multi-cavity design also significantly improves the door’s resistance to deformation.
Corrosion Resistance:
1.Natural Oxide Film: The surface of the aluminum profile easily reacts chemically with oxygen to form a thin, dense oxide film. This consumes a small portion of the surface material of the aluminum profile, but in return, it results in a more stable surface aluminum oxide. This aluminum oxide prevents the aluminum profile within the film from reacting with air and water, avoiding further consumption of aluminum material. This oxide film can last for a long time, maintaining basic corrosion resistance.
2.Surface Treatment: Anodizing significantly thickens the aluminum oxide film, making it hundreds of times thicker than natural oxide films, dramatically improving the corrosion resistance of aluminum door frames. Powder coating also enhances corrosion resistance; the high-temperature cured coating prevents aluminum from reacting with air and water in the environment.
Environmentally Friendly:
Aluminum door frames are made from extruded aluminum, and its recyclability is a major advantage. Other materials, such as wood and PVC, have very low recyclability and are often discarded due to aging. For the sake of global low-carbon goals, using environmentally friendly aluminum profiles is essential.
Lightweight and Safe:
Unlike other metals, aluminum profiles are very lightweight, thus saving labor and time costs during transportation and installation. Although aluminum door frames are relatively lightweight, they are also very resistant to pressure and impact, providing effective security even in commercial properties, protecting personal safety and property.
Aesthetically Pleasing:
Aluminum doors are often used in conjunction with glass. Surface treatments allow for a variety of selectable colors and textures on the frame surface. The transparency of the glass enhances interior brightness, creating a visually elegant and beautiful appearance.
Easy to Maintain and Clean：
The surface treatment of aluminum profiles makes the surface of aluminum door frames smooth, with dust-resistant and oil-repellent properties. Even in kitchens and bathrooms, cleaning and maintenance are easy.Usually, just wiping is sufficient to keep the surface clean.
Transparency：
Aluminum doors are generally designed with glass. The transparency of glass allows for good indoor lighting, ensuring sufficient light even when the door is closed during the day, reducing electricity costs. Aluminum-glass doors are especially suitable for balconies.
Fire Resistance：
Good aluminum-glass doors use aluminum profile frames and glass, both of which can withstand high temperatures. Even in the event of a fire, they can prevent the spread of fire, protecting people and property.
Disadvantages of Aluminum Doors
High Price:
Aluminum doors are generally more expensive than doors made of other materials. Good aluminum doors typically feature a thermal break design; the complex cavity structure and filling materials increase the complexity of the aluminum door frame production process, thus raising the price. Multi-layered glass also increases the price compared to other materials. Although the initial purchase price is high, the lower maintenance costs offset this high price.
Interior door frames are prone to condensation:
Aluminum door frames are susceptible to condensation under large temperature differences, increasing indoor humidity and promoting mold growth. Therefore, a thermally broken aluminum frame design is necessary to reduce this phenomenon.
Installation is more complex:
Aluminum doors typically require high installation precision, demanding experienced installers to prevent leaks, air leaks, loosening, deformation, and condensation on the inner glass.
Main types of aluminum doors
Compared to other door materials such as wood, metal, and plastic, aluminum profiles offer significant advantages in durability, aesthetics, environmental friendliness, functionality, and corrosion resistance. As of 2025, aluminum doors still hold a major market share. Below are some commonly used door types:
Aluminum folding doors: Including aluminum folding doors and aluminum double-folding doors, they occupy the least space and are one of the most popular door types.
Aluminum sliding doors: The sliding design is relatively effortless, and the price is lower than other aluminum doors.
Aluminum swing door：Offer good sealing and durability.
