The difference between aluminum doors and cast aluminum doors

2025-09-26

With the development of the aluminum art industry, aluminum art products are being applied to a wider range of fields. In recent years, aluminum art products have been applied to the security door market and are very popular among consumers. Some industry insiders predict that with the continuous development of aluminum doors, they are likely to replace copper doors and become the preferred choice for villas and courtyards.

Advantages of Aluminum Doors


Aluminum doors are widely used in commercial, industrial, and modern buildings.


Aluminum doors' toughness, strength, stability, and durability make them a durable product that easily attracts many homeowners. In addition to these advantages, they are corrosion-resistant, maintenance-free, easy to clean, and lightweight.


Aluminum doors are able to withstand extreme weather conditions. They are rust-free and require minimal maintenance. They also offer excellent soundproofing properties, meaning they provide sound insulation and help block outside noise from entering your home.

Advantages of Cast aluminum doors

Cast aluminum doors are becoming the preferred choice for many businesses due to their perfect balance of strength and weight. These doors are durable without the heaviness of other materials, offering the perfect combination of performance and ease of use.


Cast aluminum doors are sturdy and durable, able to withstand harsh weather conditions, frequent use, and impact. Compared to other materials like wood or steel, cast aluminum doors are less prone to denting, warping, or corroding. They require virtually no maintenance and will not rust, rot, or fade. Occasional cleaning with soap and water is generally all that's needed to maintain their appearance.

Aluminum is corrosion-resistant, with a natural oxide layer that protects against corrosion. This makes cast aluminum doors ideal for coastal areas exposed to high humidity and salt.

Cast aluminum doors can easily incorporate intricate designs and patterns, offering a wealth of customization options.

Cast aluminum doors are lighter than steel or wrought iron doors, making them easier to install and transport.

Aluminum's excellent thermal conductivity helps maintain a stable temperature inside a building. Some aluminum doors are also insulated, further enhancing energy efficiency.


The connection between aluminum doors and cast aluminum doors:



Characteristics/Aspects Aluminum Door Cast Aluminum Door
Material
Base Material Uses aluminum alloy profiles, with surface treatments such as powder coating, wood grain transfer, fluorocarbon spraying, etc. Primarily uses aluminum alloy casting, with surface treatments such as sandblasting followed by ceramic powder electrostatic spraying, etc.
Wall Thickness and Strength Relatively thin walls, designed based on the load-bearing requirements of the door frame, lightweight but with average strength and impact resistance Thicker walls, heavier texture, higher strength, and better impact resistance
Applicable Places
Aesthetic Design Diverse styles with clean and modern lines, suitable for modern residences, commercial buildings, etc. Rich textures, elegant shapes, commonly used in upscale villas, luxury homes, high-end hotels, and clubs
Installation Location Can be used for interior partition doors, balcony doors, and kitchen doors, and also for folding doors and sliding doors of storefronts Suitable for outdoor entryways, garden gates, courtyard gates, and can also be used as indoor artistic decorative doors
Performance Features
Sealing Good sealing, can be equipped with multiple sealing strips, strong protective performance, but it may be difficult to achieve high-standard sound insulation and heat preservation effects due to the limitations of aluminum profiles Excellent sealing, casting structures are more conducive to setting multiple seals, sound insulation, and heat preservation effects are more superior
Anti-Corrosion and Wear Resistance Aluminum surface has good water resistance, moisture resistance, and corrosion resistance after treatment, but wear resistance is general Sandblasting and ceramic powder spray treatment enhance surface hardness and corrosion resistance, wear resistance is better, especially suitable for outdoor environments
Stability Good structural stability, but may have slight deformation under extreme temperatures Due to material and process characteristics, it is less affected by temperature and humidity, excellent stability
Maintenance and Care
Ease of Maintenance Daily cleaning and maintenance is easy, but regular inspection of seal strips and connectors is required to prevent loosening Maintenance is relatively simple, but regular inspection of surfaces and structures is needed to ensure long-term stability
Cost
Price Lower production cost, affordable price, suitable for mass consumption Complex processes, high material costs, higher price, positioned for the high-end market
Other
Environmental Friendliness High recoverability of aluminum, in line with environmental protection concepts Higher energy consumption in the production process of cast aluminum, but the product has a long lifespan, overall environmental performance is also good
