Commercial entrances require both beauty and strength, and aluminum storefront doors deliver exactly that. Designed to handle heavy daily traffic, KDSBuilding’s aluminum doors feature robust frames, weatherproof seals, and optional multi-point locking systems that ensure maximum safety. Unlike steel, aluminum will never rust, even in coastal or humid environments, making it an ideal choice for long-term projects. The smooth surface and custom finish options make these doors not only secure but also visually appealing. With excellent structural integrity and minimal maintenance requirements, aluminum storefront doors offer the best balance between security and modern design—perfect for commercial centers, showrooms, and business offices that want to make a strong first impression. series: 55 series thermal break aluminum opening style:  casement  Color: black Glass: 5mm+9A+5mm clear tempered glass Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23 Visible Transmittance :  0.41 Air tightness :  0.15 Nail Fin Design  :  NO Door Screen :  no Grille design : no
