Choosing an aluminum, copper, or stainless steel door each has its own unique advantages and disadvantages,

depending on your budget, usage scenario, aesthetic preferences, and performance requirements.

Here's a detailed comparison:

1. Aluminum Doors

Advantages:
- Lightweight and Durable: Aluminum alloy has a low density and is lightweight, yet it's strong and resists deformation.
- Corrosion-Resistant: The surface oxide layer naturally resists rust, making it particularly suitable for humid areas (such as coastal areas and bathrooms).
- Beautiful and Versatile: A variety of colors and textures (such as wood grain and metallic) can be achieved through processes like anodizing and spray painting.
- Thermal Insulation: Paired with thermally insulated aluminum and insulating glass, it offers excellent insulation and energy savings.
- Easy to Process: Suitable for complex designs (such as sliding and folding doors).

2. Copper Doors

Advantages:
- High-End Luxury: Natural metallic texture exudes elegance and enhances the building's quality.
- Extreme Durability: Excellent corrosion resistance (patina forms a protective layer), with a lifespan of over 100 years.
- Security and Anti-theft: High hardness, strong resistance to damage, and excellent anti-theft properties.
- Antibacterial: Copper ions are naturally antibacterial, making them suitable for hospitals and food service establishments.

Disadvantages:
- Expensive: High raw material and process costs make it the most expensive of the three types.
- Maintenance Requirements: Regular cleaning and maintenance are required to prevent uneven surface oxidation (no maintenance is required if a uniform patina is desired).
- Heavy Weight: Installation requires reinforced door frames, resulting in high handling and construction costs.

Suitable Scenarios: Villa entrance doors, high-end clubs, historic building restoration, and places where security and style are paramount.

3. Stainless Steel Doors

Advantages:
- Extremely Strong: Impact-resistant, pry-resistant, and drill-resistant, offering optimal anti-theft performance (304/316 grades recommended).
- High Cost-Effective: Lower price than copper doors, more durable than aluminum doors, offering excellent overall value for money.
- Maintenance-Free: Acid and alkali resistant, rust-proof, and fade-resistant, with a long service life.
- Modern and Minimalist: The silver metallic finish is suitable for industrial and modern minimalist styles.

Critical Safety & Tips:

1. Tempered Glass is Fragile Under Pressure:Never force hinges, overtighten screws neaglass, or drill near edges.Stress points cancause instant shattering.

2.Weight: Large glass doors are extremelyheavy.Use help and proper support whenremoving/adjusting.

3.Lubrication: Only use silicone-based

lubricants (dry or spray). Oil attracts dirt;WD-40 damages plastics/rubber.

4.Professional Help Needed For:

*Replacing insulated(double-pane) glassunits.
"Replacing large ortempered glass panels
Major track/hinge replacements on heavydoors.
Any significant structural issue with theframe/wall.
·Cracked or severely damaged glass.

5.Prevention: Regular cleaning and lubricationprevent 80% of sliding door issues. Use a shower squeenee daily.
