Aluminium box section extrusion is one of the most versatile and widely used aluminum profiles in modern industries. Featuring a hollow square or rectangular cross-section, it offers an excellent combination of strength, lightweight performance, corrosion resistance, and fabrication flexibility.
At YOUHENG, we manufacture custom aluminium box section extrusions in a wide range of sizes, wall thicknesses, alloys, and surface finishes to meet the requirements of construction, transportation, industrial equipment, furniture, and engineering applications worldwide.
What Is Aluminium Box Section Extrusion?
An aluminium box section extrusion is a hollow aluminum profile produced through the extrusion process. The profile typically has a square or rectangular shape and is designed to provide high structural strength while minimizing weight.
Common alloys include:
- 6061 Aluminum
- 6063 Aluminum
- 6082 Aluminum
- 6005 Aluminum
These alloys offer excellent mechanical properties and corrosion resistance, making them suitable for both indoor and outdoor applications.

How Are Aluminium Box Section Extrusions Made?
The manufacturing process begins with high-quality aluminum billets.
Step 1: Billet Heating
Aluminum billets are heated to the required extrusion temperature.
Step 2: Extrusion Process
The heated billet is forced through a specially designed die under high pressure, creating the desired box section profile.
Step 3: Cooling and Straightening
The profile is cooled and stretched to achieve dimensional accuracy.
Step 4: Cutting
The extruded profiles are cut into specified lengths.
Step 5: Surface Treatment
Various surface finishes are available, including:
- Mill Finish
- Anodizing
- Powder Coating
- Brushing
- Sandblasting
- Electrophoresis
Step 6: Packaging and Delivery
After quality inspection, the finished aluminium box section extrusions are carefully packaged for shipment.
How Strong Are Aluminium Box Section Extrusions?
One of the key advantages of aluminium box section extrusion is its excellent strength-to-weight ratio.
Factors Affecting Strength
Alloy Grade
Higher-strength alloys such as 6061-T6 and 6082-T6 offer greater load-bearing capacity.
Wall Thickness
Increasing wall thickness improves structural rigidity and strength.
Section Dimensions
Larger cross-sectional sizes generally provide higher bending and compression resistance.
Typical Benefits
- High structural strength
- Excellent rigidity
- Lightweight construction
- Corrosion resistance
- Long service life
These properties make aluminium box section extrusions an ideal choice for structural and engineering applications.
How Much Does Aluminium Box Section Extrusion Cost?
The cost of aluminium box section extrusion depends on several factors.
Material Alloy
Different alloys have different costs.
Profile Size
Larger dimensions and thicker walls require more material and increase the overall price.
Surface Finish
Additional finishes such as anodizing or powder coating add processing costs.
Quantity
Bulk orders typically reduce the unit price significantly.
Custom Machining
Operations such as drilling, milling, punching, and CNC machining will increase production costs.
For an accurate quotation, customers should provide:
- Profile dimensions
- Wall thickness
- Alloy grade
- Surface finish requirements
- Order quantity
