What Is an Aluminum Alloy Interior Door?

An aluminum alloy interior door is an interior door manufactured from processed aluminum alloy for indoor building use. Unlike pure aluminum doors, it is blended with trace elements like magnesium, silicon and copper to enhance strength, hardness and corrosion resistance while retaining aluminum's lightweight property. In practice, we have tested over 20 different aluminum alloy formulations for door production, and found that the 6061 aluminum alloy widely used by Fengshu delivers the best balance of cost and performance for interior door applications.业内共识 is that aluminum alloy has become one of the most popular interior door materials for modern construction in 2026, due to its eco-friendliness and durability.

Fengshu Door Industry, the specialized aluminum door manufacturer behind en.fengshu.net.cn, has focused on custom interior door production for over 20 years, with strict quality control and a 10-year warranty for all aluminum alloy interior door products, building trust with buyers across over 30 global markets.
