Key features of an aluminum door include:

1. Durability: Aluminum is naturally resistant to rust and corrosion, making these doors ideal for locations with high humidity or coastal areas where saltwater can be a concern.

2. Lightweight: Despite their durability, aluminum doors are relatively lightweight compared to steel or wood doors, making them easier to handle during installation.

3. Energy Efficiency: Aluminum doors can be fitted with insulation materials or thermal breaks, improving energy efficiency by preventing heat transfer.

4. Variety of Designs: Aluminum doors come in a range of styles, from sleek and modern to traditional designs. They can be customized with glass inserts, frosted glass, or decorative panels.

5. Low Maintenance: Aluminum doors require minimal upkeep. They are not prone to warping, rotting, or swelling like wooden doors, and they retain their finish and appearance for a long time.

6. Security: With sturdy frames and the option for advanced locking mechanisms, aluminum doors offer good security.

7. Aesthetic Appeal: Available in a variety of finishes, such as anodized or powder-coated, aluminum doors can complement a wide range of architectural styles.

Overall, aluminum doors combine functionality with style, making them a popular choice for both interior and exterior applications.
