Finding the right aluminum curtain wall manufacturers is the most important step for any modern construction project. An aluminum curtain wall system provides the “skin” of the building, protecting it from the weather while creating a beautiful, modern look.
As professional aluminum curtain wall manufacturers, we specialize in high-performance aluminum alloy curtain wall solutions. We provide everything from the aluminum curtain wall profile to complete unitized aluminum curtain wall systems for skyscrapers.
Why Aluminum is the Best Choice for Curtain Walls
Leading aluminum curtain wall manufacturers prefer using aluminum alloy because it is lightweight, strong, and does not rust.
- Durability: It lasts for decades even in harsh weather.
- Design Flexibility: Can be shaped into complex aluminum curtain wall sections.
- Recyclability: Aluminum is an eco-friendly material.
- Weight: It is much lighter than steel, reducing the load on the building structure.
Types of Aluminum Curtain Wall Systems
As experienced aluminum curtain wall manufacturers, we offer different system types to meet your specific project needs.
1. Stick-Built Curtain Wall System
It is very flexible and cost-effective for smaller buildings.
2. Unitized Aluminum Curtain Wall
In this system, large units are pre-assembled and glazed in our factory. These units are then shipped to the site and hung onto the building.
- Fast Installation: Reduces labor time on-site.
- High Quality: Better seals and joints because it is made in a controlled factory environment.

Technical Specifications for Aluminum Profiles
Quality aluminum curtain wall manufacturers must follow strict technical standards. We use premium alloys to ensure structural safety.
Alloy and Temper Specifications
| Material Component | Standard Grade | High-Strength Grade |
|---|---|---|
| Aluminum Alloy | 6063 | 6061 |
| Temper State | T5 | T6 |
| Tensile Strength | ≥160 MPa | ≥260 MPa |
| Elongation | ≥8% | ≥10% |
| Hardness | ≥8 Webster | ≥15 Webster |
Profile Dimensions (Digital Specs)
| Profile Type | Depth Range (mm) | Face Width (mm) | Thickness (mm) |
|---|---|---|---|
| Main Mullion | 120 mm−250 mm | 50 mm−65 mm | 2.5 mm−5.0 mm |
| Horizontal Transom | 50 mm−160 mm | 50 mm−65 mm | 2.0 mm−3.0 mm |
| Pressure Plate | 15 mm−25 mm | 50 mm | 1.5 mm−2.5 mm |
Aluminum Storefront vs. Curtain Wall
Many clients ask aluminum curtain wall manufacturers about the difference between a storefront and a curtain wall. While they look similar, their performance is very different.
| Feature | Aluminum Storefront | Aluminum Curtain Wall |
|---|---|---|
| Structural Support | Supported by floor/slab | Hangs from the building |
| Max Height | Usually ground floor (<12 feet) | Unlimited height |
| Water Drainage | Weep holes at bottom | Internal drainage per floor |
| Thermal Performance | Standard | High (Thermal breaks) |
Surface Finishing Options
To protect the aluminum curtain wall frame, we offer several high-quality surface treatments:
- Anodized Aluminum Curtain Wall: Provides a natural metallic look that is extremely hard and scratch-resistant.
- Powder Coating: Available in thousands of RAL colors. It provides a thick, protective layer.
- PVDF Coating: The best choice for coastal areas. It resists UV rays and salt spray for over 20 years.
- Wood Grain Finish: Gives the appearance of wood with the strength of aluminum.
Key Applications of Aluminum Curtain Walls
- Commercial Offices: Create professional, high-light work environments.
- Shopping Centers: Large aluminum glass curtain walls are used for storefronts and atriums.
- Hotels & Resorts: Floor-to-ceiling views for guest rooms and lobbies.
- Public Infrastructure: Airports, train stations, and hospitals.
- Residential Skyscrapers: High-end apartments using unitized aluminum curtain walls.
Choosing the Best Aluminum Curtain Wall Manufacturers
When selecting a partner, you should look for several key factors:
- Manufacturing Precision: The aluminum curtain wall section must be cut and punched with CNC accuracy.
- Design Support: We provide an aluminum curtain wall design guide manual and CAD drawings for your engineers.
- Testing & Certification: Our systems are tested for wind pressure, air infiltration, and water resistance.
- Global Logistics: We can ship aluminum curtain wall details and components to the US, Europe, and Southeast Asia.
Frequently Asked Questions (FAQ)
1. What is the standard thickness of an aluminum curtain wall profile?
For structural mullions, the thickness usually ranges from 2.5 mm to 5.0 mm depending on the height of the building and wind loads.
2. Is aluminum better than steel for curtain walls?
Yes, for most projects. Aluminum is 1/3 the weight of steel, making it easier to install. It also has much better natural resistance to corrosion.
3. Can you customize the aluminum curtain wall section?
Absolutely. As custom aluminum curtain wall manufacturers, we can create new extrusion dies to match your specific architectural design.
4. How do you ensure the system is waterproof?
We use a “pressure-equalized” design. This uses a system of gaskets and internal drainage channels to ensure that any water that enters is immediately channeled back to the outside.
