Aluminum Door Styles
Un-insulated Aluminum Doors: The most basic type consists of a single aluminum frame and panels without thermal breaks or insulation inside. Uninsulated aluminum doors are lightweight and affordable, but perform worse in extreme weather.
Aluminum Clad Wood Doors: These consist of wood doors covered in durable, low-maintenance aluminum cladding. This combines the warmth and aesthetic of wood with enhanced weatherproofing.
Thermally Broken Aluminum Doors: Thermal breaks made of plastic, vinyl, or composite inserts interrupt heat flow across aluminum frame and panel members. This boosts energy efficiency.
Polyurethane Foam-Filled Aluminum Doors: Injecting cavity spaces with polyurethane foam as insulation inside aluminum door frames and panels improves thermal performance the most.
Aesthetic and Design Flexibility

Aluminum windows have series such as 50, 55, 70, 76, 118, and 130, which should be selected based on the size of the window opening and wind pressure. Aluminum sliding windows for home use should not be less than series 55.
Strength: The tensile strength of aluminum alloy doors should reach 157N/square millimeter, and the yield strength should reach 108N/square millimeter.
Evenness: The surface of the aluminum alloy should be smooth without any dents or bulges.
Glossiness: There should be no bubbles or ash residue on the surface of heavy-duty aluminum doors. These impurities appear as white and black spots on the aluminum alloy.
Oxidation: The surface of the aluminum alloy will be plated with a layer of oxide film, which should reach a thickness of 10 micrometers.
