YOUHENG provides custom aluminum rounded corner extrusions reach to your exact requirements — from extrusion design and precise production to surface finishing and specialized machining (CNC) services.
What is rounded corner aluminum extrusion?
It is a type of aluminum profile designed with smooth, curved edges instead of sharp corners. It is produced through the aluminum extrusion process and is commonly used in architectural, decorative, and industrial applications.
Compared with standard sharp-edged profiles, rounded corner extrusions provide a cleaner appearance and improved safety by reducing sharp edges.
What is rounded corner aluminum extrusion used for?
Rounded corner aluminum extrusion is widely used in applications that require a smooth appearance, safer edges, and lightweight structural support.
1. Aluminum Awning Extrusions
- Patio awnings
- Window awnings
- Garden awnings
- Commercial storefront awnings
The smooth corners improve appearance and reduce sharp edges in outdoor structures.
2. Window and Door Frames
- Aluminum windows
- Sliding doors
- Curtain wall systems
Rounded corners help create a cleaner architectural style.
3. Furniture and Interior Decoration
- Cabinets
- Shelving systems
- Tables and furniture frames
- Decorative trims
They provide a modern appearance and improve safety in indoor environments.
4. Industrial Equipment
- Machine frames
- Automation equipment
- Protective covers
- Aluminum enclosures
The smooth edges help improve handling and reduce damage risks.
5. Display and Exhibition Systems
- Retail displays
- Exhibition booths
- Sign frames
- Advertising structures
Their lightweight structure makes installation easier.
6. Outdoor Architectural Projects
- Pergolas
- Sunshade systems
- Railings
- Decorative outdoor structures
Because aluminum has good weather resistance, it performs well in outdoor environments.
How are rounded corner aluminum extrusions made?
How to cut rounded corner aluminum extrusions?
1. Miter Saw Cutting
A miter saw with a carbide-tipped aluminum cutting blade is one of the most common methods.
It is suitable for:
- Straight cuts
- Angle cuts
- Small and medium production
Advantages
- Fast cutting
- Easy operation
Disadvantages
- burrs
2. CNC Saw Cutting
CNC cutting machines are widely used for industrial aluminum extrusion fabrication.
They provide:
- High cutting precision
- Automatic positioning
- Consistent quality
CNC cutting is ideal for:
- Mass production
- Tight tolerance requirements
- Custom aluminum extrusion projects
3. Band Saw Cutting
Band saws are commonly used for thicker or larger aluminum extrusion profiles.
This method is suitable for:
- Heavy-duty profiles
- Large structural sections
- Industrial applications
Additional deburring may be required after cutting.
4. Laser Cutting
Laser cutting is mainly used for detailed fabrication work, including:
- Holes
- Slots
- Complex shapes
It offers high precision and clean edges for customized aluminum extrusion processing.
5. Manual Cutting Tools
For small projects or on-site installation, portable tools can also be used:
- Circular saws
- Hacksaws
- Portable aluminum cutting machines
This method is flexible but less precise than CNC processing.
Common Applications
Cut rounded corner aluminum extrusions are widely used for:
- Aluminum awnings
- Window and door systems
- Furniture frames
- Industrial equipment
- Display structures
How straight are rounded corner aluminum extrusions?
Rounded corner aluminum extrusions are generally manufactured with good straightness, especially when produced using high-quality extrusion equipment and proper post-processing methods.
Most rounded corner aluminum extrusions made from 6063 aluminum alloy can achieve excellent straightness for architectural and industrial applications.
Standard Version Straightness tolerance: ≤1 mm per meter.
Precision Version High precision straightness tolerance available: ≤0.5 mm per meter.
How strong are rounded corner aluminum extrusions?
1. Strength of 6063 Aluminum Extrusions
6063 aluminum is the most common material for architectural extrusions.
Typical mechanical properties of 6063-T5/T6:
- Tensile strength: approximately 160–240 MPa
- Yield strength: approximately 110–200 MPa
6063 provides:
- Good corrosion resistance
- Smooth surface finish
- Good extrusion performance
- Moderate structural strength
It is widely used for:
- Awning frames
- Window and door systems
- Decorative structures
- Outdoor architectural profiles
2. Strength of 6061 Aluminum Extrusions
6061 aluminum offers higher strength than 6063.
Typical mechanical properties of 6061-T6:
- Tensile strength: approximately 290 MPa
- Yield strength: approximately 240 MPa
6061 is commonly used for:
- Structural frames
- Industrial equipment
- Heavy-duty applications
- CNC machined components
3. Common Applications Requiring Strength
Rounded corner aluminum extrusions are commonly used for:
- Aluminum awnings
- Pergolas
- Window frames
- Furniture systems
- Display structures
- Industrial enclosures
- Automation equipment
