Where natural light is a priority, our Tempered Glass Interior Aluminum Door seamlessly merges corrosion resistance with expansive glass panels, creating airy, open-concept rooms without compromising structural integrity. Completing the collection, the Full Aluminum Panel Interior Door offers a minimalist, ultra-modern aesthetic with a fully flush surface that excels in damp areas like bathrooms and basements. Each door is precision-crafted from 6063-T5 aluminum alloy and undergoes a rigorous 12-step pretreatment and powder-coating process, ensuring decades of corrosion-free operation in coastal, humid, or chemically exposed indoor settings.

The Corrosion Resistant Interior Aluminum Door is built around a robust aluminum frame filled with a high-density polyurethane foam core, delivering exceptional thermal and acoustic insulation. Its surface is treated with a proprietary anodic oxidation layer followed by a marine-grade polyester powder coat, achieving a salt spray resistance rating of over 3,000 hours per ASTM B117 standards. This makes the door impervious to condensation, mold, and household chemicals. Key product specifications are outlined below.
