Types, Characteristics, and Material Requirements of Aluminum Doors

Aluminum doors are door frame components made by processing surface-treated aluminum alloy profiles through cutting, drilling, milling, tapping, production, assembly, and other processing techniques, and then assembling them together with connectors, sealing materials, opening and closing hardware fittings, and glass.

Types of aluminum external doors

  • Aluminum doors based on the opening method: sliding aluminum doors, swing aluminum doors, folding aluminum doors, and hanging aluminum doors.

  • Aluminum alloy doors based on width: 46 series, 50 series, 65 series, 70 series, and 90 series aluminum alloy doors.

Characteristics of China aluminum doors

Light and strong

Aluminum alloy materials are mostly hollow thin-walled composite sections that are easy to use and reduce weight. The cross-section has a high bending strength, and the door made from it is durable and less prone to deformation.

Good sealing performance

Aluminum alloy is easy to extrude, and the cross-sectional dimensions of the profiles are precise, with high processing accuracy. Various sealing materials with good water resistance, elasticity, and durability can be selected, such as rubber pressure strips and silicone sealant series. In terms of profiles, various sealing strips are fixed in grooves, which have been completed uniformly with the cross-section during the extrusion process, creating favorable conditions for installing sealing materials.

Beautiful appearance

After the aluminum alloy door surface is anodized, it can show colors such as antique bronze, golden yellow, and silver white, which can be freely selected and become shiny after oxidation. The window frame is large and can be fitted with a relatively large area of glass, allowing sufficient indoor light and enhancing the contrast between the interior and exterior surfaces, making the living space more layered.

Strong corrosion resistance

The aluminum alloy oxide film does not fade, peel, or require painting, is easy to maintain, and does not need repair.


Requirements for aluminum door materials

  • Thickness: Aluminum sliding doors provided by aluminum door factory are available in several series such as 75, 88, 103, and 120, with 88 series being commonly used in homes. 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.

Precautions when choosing custom aluminum storm doors

  • The decoration surface of the door should not have obvious damage and scratches, and the protective film on the surface should not be scratched.

  • The adjacent components on the door should not have obvious color difference, which affects the surface aesthetics of aluminum doors.

  • Aluminum chips, burrs, oil stains, and stains should not appear on the surface of the aluminum doors. The aluminum alloy is connected and combined with screws and nails, and too many exposed nail holes should not be present on the surface of the installed aluminum alloy.
