Core Advantages of Aluminum Alloy Interior Doors

Superior Durability & Low Maintenance

Actual testing from Fengshu’s quality lab shows that high-quality aluminum alloy interior doors resist moisture, warping, scratching and mold 3 times longer than solid wood doors. This makes them ideal for bathrooms, kitchens and commercial office spaces.

Customizable Aesthetics & Eco-Friendliness

From our custom project cases, aluminum alloy can be finished to match any design style, from minimalist modern to industrial, with options for wood grain textures, matte or glossy surfaces. 100% of aluminum material is recyclable, making it a much more sustainable choice than non-recyclable PVC doors per 2026 green building research.
